Microsoft's controversial "Recall" feature (in a public preview of Windows 11) already has some known issues, Microsoft admitted Friday. For example:

- Recall can be enabled or disabled from "Turn Windows features on or off". We are caching the Recall binaries on disk while we test add/remove. In a future update we will completely remove the binaries.

- You must have Secure Boot enabled for Recall to save snapshots.

- Some users experience a delay before snapshots first appear in the timeline while using their device. If snapshots do not appear after 5 minutes, reboot your device. If saving snapshots is enabled, but you see snapshots are no longer being saved, reboot your device.

- Clicking links within Recall to submit feedback may experience a delay in loading the Feedback Hub application. Be patient and it will display.

CNBC adds that according to Microsoft Recall "won't work with some accessibility programs, and if you specify that Recall shouldn't save content from a given website, it might get captured anyway while using the built-in Edge browser..." But those aren't the only issues CNBC noticed: - While you might expect that your computer will be recording every last thing you look at once you've turned on Recall, it can go several minutes between making snapshots, leaving gaps in the timeline.

- Recall allows you to prevent screenshots from being made when you're accessing specific apps. But a few apps installed on my Surface Pro are not shown on that list.

- When you enter a search string to find words, results might be incomplete or incorrect. Recall clearly had two screen images that mention "Yankees," but when I typed that into the search box, only one of them came up as a text match. I typed in my last name, which appeared in eight images, but Recall produced just two text matches.

- Recall made a screenshot while I was scrolling through posts on social network BlueSky, and one contains a photo of a New York street scene. You can see a stoplight, a smokestack and street signs. I typed each of those into the search box, but Recall came up with no results...

- The search function is fast, but flipping through snapshots in Recall is not. It can take a couple of seconds to load screenshots as you swipe between them.

The GitHub Secure Open Source Fund launched this week with an initial commitment of $1.25 million, reports TechCrunch, using "capital from contributors including American Express, 1Password, Shopify, Stripe, and GitHub's own parent company Microsoft." GitHub briefly teased the new initiative at its annual GitHub Universe developer conference last month, but Tuesday it announced full details and formally opened the program for applicants, which will be reviewed "on a rolling basis" through the closing date of January 7, 2025, with programming and funding starting shortly after...

Tuesday's news builds on a number of previous GitHub initiatives designed to support project maintainers that work on key components of critical software, including GitHub Sponsors which landed in 2019 (and which is powering the new fund), but more directly the GitHub Accelerator program that launched its first cohort last year — the GitHub Secure Open Source Fund is essentially an extension of that.

"We're trying to acknowledge the fact that we're the home of open source, ultimately, and we have an obligation to help ensure that open source can continue to thrive and have the support that it needs," GitHub Chief Operating Officer Kyle Daigle told TechCrunch in an interview. Qualifying projects can be pretty much any project that has an open source license, but of course GitHub will be looking at those that need the funds most — so Kubernetes can hold fire with its application. "We're looking for the outsized impact, which tends to be big projects with few maintainers that we all rely on," Daigle said.

The sum of $1.25 million might sound like a reasonable amount, but it will be split across 125 projects, which means just $10,000 each — better than nothing, for sure, but a drop in the ocean on the grand scheme of things. However, Daigle is quick to stress that money is only part of the prize here — as with the initial accelerator program, maintainers embark on a three-week program, which includes mentorship, certification, education workshops, and ongoing access to GitHub tools.
From GitHub's announcement: Since introducing support for organizations through GitHub Sponsors, more than 5,800 organizations, including Microsoft and Stripe, have invested in maintainers and projects on GitHub, up nearly 40% YoY. Cumulatively, the platform has unlocked over $60 million in funding for maintainers to help them spend more time working on their projects.

But we know we're just scratching the surface when it comes to organizations and corporate support of open source. This summer, we partnered with the Linux Foundation and researchers from Laboratory for Innovation Science at Harvard (LISH) to learn more about the state of open source funding today. Diving in, we assessed organizations funding behaviors, potential misalignments, and opportunities to improve. In the report launched today, we found:


- Responding organizations annually invest $1.7 billion in open source, which can be extrapolated to estimate that approximately $7.7 billion is invested across the entire open source ecosystem annually.

- 86% of investment is in the form of contribution labor by employees and contractors working for the funding organization, with the remaining 14% being direct financial contributions.

- Organizations generally know how and where they contribute (65%) but lack specific clarity of their contributions (38%).

- Security efforts focus on bugs and maintenance; only a few (6%) said comprehensive security audits are a priority.


We all stand to benefit from unlocking more funding for open source. By tackling problems like open source security as an ecosystem, we believe we can help create more available funding and resources that are vital to the sustainability of open source. Not every open source project or maintainer has access to funding and training for security. That's why we created a fund that everyone potentially eligible can apply for...

This is the beginning of a journey into helping find ways to secure open source. On its own, it's not the answer, but we are confident it will help. We will be monitoring the impact of these investments and share what we learn as we go.

Microsoft-owned GitHub published a blog post asking "Does GitHub Copilot improve code quality? Here's what the data says."

Its first paragraph includes statistics from past studies — that GitHub Copilot has helped developers code up to 55% faster, leaving 88% of developers feeling more "in the flow" and 85% feeling more confident in their code.

But does it improve code quality? [W]e recruited 202 [Python] developers with at least five years of experience. Half were randomly assigned GitHub Copilot access and the other half were instructed not to use any AI tools... We then evaluated the code with unit tests and with an expert review conducted by developers.

Our findings overall show that code authored with GitHub Copilot has increased functionality and improved readability, is of better quality, and receives higher approval rates... Developers with GitHub Copilot access had a 56% greater likelihood of passing all 10 unit tests in the study, indicating that GitHub Copilot helps developers write more functional code by a wide margin. In blind reviews, code written with GitHub Copilot had significantly fewer code readability errors, allowing developers to write 13.6% more lines of code, on average, without encountering readability problems. Readability improved by 3.62%, reliability by 2.94%, maintainability by 2.47%, and conciseness by 4.16%. All numbers were statistically significant... Developers were 5% more likely to approve code written with GitHub Copilot, meaning that such code is ready to be merged sooner, speeding up the time to fix bugs or deploy new features.
"While GitHub's reports have been positive, a few others haven't," reports Visual Studio magazine: For example, a recent study from Uplevel Data Labs said, "Developers with Copilot access saw a significantly higher bug rate while their issue throughput remained consistent."

And earlier this year a "Coding on Copilot" whitepaper from GitClear said, "We find disconcerting trends for maintainability. Code churn — the percentage of lines that are reverted or updated less than two weeks after being authored — is projected to double in 2024 compared to its 2021, pre-AI baseline. We further find that the percentage of 'added code' and 'copy/pasted code' is increasing in proportion to 'updated,' 'deleted,' and 'moved 'code. In this regard, AI-generated code resembles an itinerant contributor, prone to violate the DRY-ness [don't repeat yourself] of the repos visited."

"You can use any Linux distribution inside of the Windows Subsystem for Linux" Microsoft recently reminded Windows users, "even if it is not available in the Microsoft Store, by importing it with a tar file."

But being an official distro "makes it easier for Windows Subsystem for Linux users to install and discover it with actions like wsl --list --online and wsl --install," Microsoft pointed out this week. And "We're excited to announce that Red Hat will soon be delivering a Red Hat Enterprise Linux WSL distro image in the coming months..."

Thank you to the Red Hat team as their feedback has been invaluable as we built out this new architecture, and we're looking forwards to the release...! Ron Pacheco, senior director, Red Hat Enterprise Linux Ecosystem, Red Hat says:

"Developers have their preferred platforms for developing applications for multiple operating systems, and WSL is an important platform for many of them. Red Hat is committed to driving greater choice and flexibility for developers, which is why we're working closely with the Microsoft team to bring Red Hat Enterprise Linux, the largest commercially available open source Linux distribution, to all WSL users."
Read Pacheco's own blog post here.

But in addition Microsoft is also releasing "a new way to make WSL distros," they announced this week, "with a new architecture that backs how WSL distros are packaged and installed." Up until now, you could make a WSL distro by either creating an appx package and distributing it via the Microsoft Store, or by importing a .tar file with wsl -import. We wanted to improve this by making it possible to create a WSL distro without needing to write Windows code, and for users to more easily install their distros from a file or network share which is common in enterprise scenarios... With the tar based architecture, you can start with the same .tar file (which can be an exported Linux container!) and just edit it to add details to make it a WSL distro... These options will describe key distro attributes, like the name of the distro, its icon in Windows, and its out of box experience (OOBE) which is what happens when you run WSL for the first time. You'll notice that the oobe_command option points to a file which is a Linux executable, meaning you can set up your full experience just in Linux if you wish.

Longtime Slashdot reader theodp writes: Past corporate-sponsored Hour of Code tutorials for the nation's schoolchildren have blurred the lines between coding lessons and product infomercials. So too is the case again with this year's newly-announced Hour of Code 2024 flagship tutorials, which include Microsoft Minecraft, Amazon Music, and Transformers One movie-themed intros to coding. The press release announcing the tutorials from tech-backed nonprofit Code.org, which organizes the Hour of Code and counts Microsoft and Amazon as $30+ million donors, boasts of its "decade of partnership with [Microsoft] Minecraft this year, reaching more than 300 million sessions of Minecraft Hour of Code since 2015!"

Interestingly, The Transformers (Paramount Pictures, which released Transformers One in the U.S., is a $25,000+ Code.org donor) is cited as one of the OG's of children's Saturday morning cartoon advertising (aka 30-minute commercials) that prompted the Children's Television Act (CTA) of 1990, an act of Congress that ordered the FCC to put in place regulations to protect children from advertising. Throughout the 1980s, Action for Children's Television (ACT) criticized children's television programs that "blur(red) the distinction between program content and commercial speech."

"Steven Adair, of cybersecurity firm Veloxity, revealed at the Cyberwarcon security conference how Russian hackers were able to daisy-chain as many as three separate Wi-Fi networks in their efforts to attack victims," writes Longtime Slashdot reader smooth wombat. Wired reports: Adair says that Volexity first began investigating the breach of its DC customer's network in the first months of 2022, when the company saw signs of repeated intrusions into the customer's systems by hackers who had carefully covered their tracks. Volexity's analysts eventually traced the compromise to a hijacked user's account connecting to a Wi-Fi access point in a far end of the building, in a conference room with external-facing windows. Adair says he personally scoured the area looking for the source of that connection. "I went there to physically run down what it could be. We looked at smart TVs, looked for devices in closets. Is someone in the parking lot? Is it a printer?" he says. "We came up dry."

Only after the next intrusion, when Volexity managed to get more complete logs of the hackers' traffic, did its analysts solve the mystery: The company found that the hijacked machine which the hackers were using to dig around in its customer's systems was leaking the name of the domain on which it was hosted -- in fact, the name of another organization just across the road. "At that point, it was 100 percent clear where it was coming from," Adair says. "It's not a car in the street. It's the building next door." With the cooperation of that neighbor, Volexity investigated that second organization's network and found that a certain laptop was the source of the street-jumping Wi-Fi intrusion. The hackers had penetrated that device, which was plugged into a dock connected to the local network via Ethernet, and then switched on its Wi-Fi, allowing it to act as a radio-based relay into the target network. Volexity found that, to break into that target's Wi-Fi, the hackers had used credentials they'd somehow obtained online but had apparently been unable to exploit elsewhere, likely due to two-factor authentication.

Volexity eventually tracked the hackers on that second network to two possible points of intrusion. The hackers appeared to have compromised a VPN appliance owned by the other organization. But they had also broken into the organization's Wi-Fi from another network's devices in the same building, suggesting that the hackers may have daisy-chained as many as three networks via Wi-Fi to reach their final target. "Who knows how many devices or networks they compromised and were doing this on," says Adair. Volexity had presumed early on in its investigation that the hackers were Russian in origin due to their targeting of individual staffers at the customer organization focused on Ukraine. Then in April, fully two years after the original intrusion, Microsoft warned of a vulnerability in Windows' print spooler that had been used by Russia's APT28 hacker group -- Microsoft refers to the group as Forest Blizzard -- to gain administrative privileges on target machines. Remnants left behind on the very first computer Volexity had analyzed in the Wi-Fi-based breach of its customer exactly matched that technique. "It was an exact one-to-one match," Adair says.

Microsoft has released a public preview of its redesigned Windows Recall feature, five months after withdrawing the original version due to security concerns. The feature will initially be available only on Qualcomm Snapdragon X Elite and Plus Copilot+ PCs running Windows Insider Dev channel build 26120.2415.

Recall, which continuously captures and indexes screenshots and text for later search, now includes mandatory encryption, opt-in activation, and Windows Hello authentication. The feature requires Secure Boot, BitLocker encryption, and attempts to automatically mask sensitive data like passwords and credit card numbers. The feature is exclusive to Copilot+ PCs equipped with neural processing units for local AI processing.

According to Business Insider (paywalled), Microsoft's Copilot tool inadvertently let customers access sensitive information, such as CEO emails and HR documents. Now, Microsoft is working to fix the situation, deploying new tools and a guide to address the privacy concerns. The story was highlighted by Salesforce CEO Marc Benioff. From the report: These updates are designed "to identify and mitigate oversharing and ongoing governance concerns," the company said in a blueprint for Microsoft's 365 productivity software suite. [...] Copilot's magic -- its ability to create a 10-slide road-mapping presentation, or to summon a list of your company's most profitable products -- works by browsing and indexing all your company's internal information, like the web crawlers used by search engines. IT departments at some companies have set up lax permissions for who can access internal documents -- selecting "allow all" for the company's HR software, say, rather than going through the trouble of selecting specific users.

That didn't create much of a problem because there wasn't a tool that an average employee could use to identify and retrieve sensitive company documents -- until Copilot. As a result, some customers have deployed Copilot only to discover that it can let employees read an executive's inbox or access sensitive HR documents. "Now when Joe Blow logs into an account and kicks off Copilot, they can see everything," a Microsoft employee familiar with customer complaints said. "All of a sudden Joe Blow can see the CEO's emails."

Microsoft has expanded its campaign to migrate Windows 10 users to Windows 11, deploying full-screen ads urging users to purchase new computers ahead of Windows 10's end-of-support date. The ads, appearing on Windows 10 devices, remind the October 14, 2025 cut-off date for OS support.

An anonymous reader shares a report: Lawyers for The New York Times and Daily News, which are suing OpenAI for allegedly scraping their works to train its AI models without permission, say OpenAI engineers accidentally deleted data potentially relevant to the case. Earlier this fall, OpenAI agreed to provide two virtual machines so that counsel for The Times and Daily News could perform searches for their copyrighted content in its AI training sets.

In a letter, attorneys for the publishers say that they and experts they hired have spent over 150 hours since November 1 searching OpenAI's training data. But on November 14, OpenAI engineers erased all the publishers' search data stored on one of the virtual machines, according to the aforementioned letter, which was filed in the U.S. District Court for the Southern District of New York late Wednesday. OpenAI tried to recover the data -- and was mostly successful. However, because the folder structure and file names were "irretrievably" lost, the recovered data "cannot be used to determine where the news plaintiffs' copied articles were used to build [OpenAI's] models," per the letter. "News plaintiffs have been forced to recreate their work from scratch using significant person-hours and computer processing time," counsel for The Times and Daily News wrote.

An anonymous reader quotes a report from GeekWire: Microsoft and Atom Computing say they've reached a new milestone in their effort to build fault-tolerant quantum computers that can show an advantage over classical computers. Microsoft says it will start delivering the computers' quantum capabilities to customers by the end of 2025, with availability via the Azure cloud service as well as through on-premises hardware. "Together, we are co-designing and building what we believe will be the world's most powerful quantum machine," Jason Zander, executive vice president at Microsoft, said in a LinkedIn posting.

Like other players in the field, Microsoft's Azure Quantum team and Atom Computing aim to capitalize on the properties of quantum systems -- where quantum bits, also known as qubits, can process multiple values simultaneously. That's in contrast to classical systems, which typically process ones and zeros to solve algorithms. Microsoft has been working with Colorado-based Atom Computing on hardware that uses the nuclear spin properties of neutral ytterbium atoms to run quantum calculations. One of the big challenges is to create a system that can correct the errors that turn up during the calculations due to quantum noise. The solution typically involves knitting together "physical qubits" to produce an array of "logical qubits" that can correct themselves.

In a paper posted to the ArXiv preprint server, members of the research team say they were able to connect 256 noisy neutral-atom qubits using Microsoft's qubit-virtualization system in such a way as to produce a system with 24 logical qubits. "This represents the highest number of entangled logical qubits on record," study co-author Krysta Svore, vice president of advanced quantum development for Microsoft Azure Quantum, said today in a blog posting. "Entanglement of the qubits is evidenced by their error rates being significantly below the 50% threshold for entanglement." Twenty of the system's logical qubits were used to perform successful computations based on the Bernstein-Vazirani algorithm, which is used as a benchmark for quantum calculations. "The logical qubits were able to produce a more accurate solution than the corresponding computation based on physical qubits," Svore said. "The ability to compute while detecting and correcting errors is a critical component to scaling to achieve scientific quantum advantage."

An anonymous reader quotes a report from Ars Technica: Microsoft Flight Simulator 2024 is out today (Xbox/PC, Steam), and it packs in a whole lot of simulation. It's hard to imagine topping the 2020 version, which contained the entire world, at scale, 3D modeled and able to be flown over. It had real-time weather and rather detailed physics. You could theoretically fly a helicopter back to your high school football field and land on it, like 15-year reunion royalty.

What could come next? A lot, including a world simulation that Microsoft repeatedly describes as Earth's "full digital twin." There are few, if any, real "reviews" up yet, given the size of the game and seemingly late access for reviewers. As such, I offer up all the notable things packed into this latest release so that those with flight sticks, patience, and a desire to get way up yonder can decide whether to take off. These are the most "notable things" available in this latest release, as highlighted by Ars' Kevin Purdy:

- The file size is much smaller than the 2020 version, totaling "around 30GB"
- You can expect ~5GB an hour of streaming data (up-close data is streamed on demand; flying high-up in the skies uses pre-loaded data)
- AI learning has allowed for "4,000 times more" detail in textures and terrain meshes
- Aircraft and airports you customized or purchased are carried over from 2020 into 2024
- There's a new Career Mode, with 26 different paths
- Animals have more realistic behavior -- e.g. sheep head inside when it's raining, birds migrate, and elephants will be more aware of your flybys
- Flight Simulator 2020 will continue to get support

Microsoft has announced sweeping changes to Windows security architecture, including new recovery capabilities designed to prevent system-wide outages following July's CrowdStrike incident that disabled 8.5 million Windows devices.

The Windows Resiliency Initiative introduces Quick Machine Recovery, allowing IT administrators to remotely fix unbootable systems through an enhanced Windows Recovery Environment. Microsoft is also mandating stricter testing and deployment practices for security vendors under its Microsoft Virus Initiative, including gradual rollouts and monitoring procedures.

The company is also developing a framework to move antivirus processing outside the Windows kernel, with a preview planned for security partners in July 2025.

Microsoft is planning to launch a new purpose-built miniature PC for its Windows 365 cloud service next year. The Verge: Windows 365 Link is a $349 device that acts like a thin client PC to connect to the cloud and stream a version of Windows 11. The Link device is designed to be a compact, fanless, and easy-to-use cloud PC for your local monitors and peripherals. It's meant to be the ideal companion to Microsoft's Windows 365 service, which lets businesses transition employees over to virtual machines that exist in the cloud and can be streamed securely to multiple devices. Windows 365 Link cannot run local apps.

In a technical blog post, Microsoft veteran Raymond Chen has explained why Windows 95's installation process required users to pass through three different operating systems -- MS-DOS, Windows 3.1, and Windows 95. The design choice stemmed from the need to support upgrades from multiple starting points while maintaining a graphical user interface throughout the process.

Rather than creating separate installers for MS-DOS, Windows 3.1, and Windows 95 users, developers opted for a unified approach using three chained setup programs. The process began with installing a minimal version of Windows 3.1 when starting from MS-DOS, followed by a 16-bit Windows application that handled core installation tasks, and concluded with a 32-bit Windows 95 program for final configuration steps.

According to Bloomberg, the U.S. Justice Department wants Google to sell off its Chrome browser as part of its ongoing search monopoly case. The recommendations will be made official on Wednesday. 9to5Google reports: At the top of the list is having Google sell Chrome "because it represents a key access point through which many people use its search engine." There are many questions about how that works, including what the impact on the underlying Chromium codebase would be. Would Google still be allowed to develop the open-source project by which many other browsers, like Microsoft Edge use? "The government has the option to decide whether a Chrome sale is necessary at a later date if some of the other aspects of the remedy create a more competitive market," reports Bloomberg. Google, which plans to appeal, previously said that "splitting off Chrome or Android would break them."

Bloomberg reports that "antitrust officials pulled back from a more severe option that would have forced Google to sell off Android." However, the government wants Google to "uncouple its Android smartphone operating system from its other products, including search and its Google Play mobile app store, which are now sold as a bundle." Meanwhile, other recommendations include licensing Google Search data and results, as well as allowing websites that are indexed for Search to opt out of AI training.

This week Alphabet CEO Sundar Picahi assured investors that their long-term AI focus and investment (and a "commitment to innovation") "are paying off," reports the Associated Press. Alphabet's stock has already soared 20% this year, and it's "still thriving" as the company "navigates through a pivotal shift to AI and battles regulators..." Alphabet earned $26.3 billion, or $2.12 per share during the most recent quarter, a 34% increase from a year ago. Revenue rose 15% from the same time last year to $88.27 billion... The profits would have been even higher if Google wasn't pouring so much money into building up its AI arsenal in a technological arms race that includes other industry heavyweights Microsoft, Amazon, Apple, Facebook parent Meta Platforms and rising star OpenAI. The AI investments are the primary reason Google's capital expenditures in the past quarter soared 62% from the same time last year to $13.1 billion. The AI spending will likely stay at roughly the same level during the current October-December period, and the rise even higher next year, according to Anat Ashkenazi, Alphabet's chief financial officer.

But Ashkenazi also emphasized the Mountain View, California, company will act on cost-cutting opportunities in other areas to help boost profits. Alphabet already has trimmed its payroll from more than 190,000 worldwide employees early last year to about 181,000 workers now. In an example of how AI can perform tasks that once required human brainpower, Pichai said the technology is now writing more than 25% of the company's new computer coding.
After the results, investors sent Alphabet's stock price up 5% in extended trading, the article points out. "Both Alphabet's profit and revenue increased at a brisker pace than industry analysts anticipated, thanks primarily to a moneymaking machine powered by Google's ubiquitous search engine... [Google's digital search-engine ads earned $49.39 billion, 12% more than the same quarter of 2023.] And Google's cloud division is growing at an even more robust rate, thanks to demand for AI services. The cloud division generated $11.35 billion in revenue during the past quarter, a 35% increase from last year."

And meanwhile over at Microsoft, quarterly sales surged 16% to $65.6 billion, reports the Associated Press. But again, "the company sought to assure investors its huge spending on artificial intelligence is paying off." The company has spent billions of dollars to expand its global network of data centers and other physical infrastructure required to develop AI technology... As a result, AI-related products are now on track to contribute about $10 billion to the company's annual revenue, the "fastest business in our history to reach this milestone," CEO Satya Nadella said on a call with analysts Wednesday. [Though Microsoft "hasn't yet formally reported revenue specifically from AI products," the article notes later, with Microsoft instead saying it's infused AI and Copilot into all its business segments.]
Just in the last quarter, Microsoft spent $20 billion "mostly for its cloud computing and AI needs," the article points out.

But there's still making plenty of money... The software maker also reported an 11% increase in quarterly profit to $24.7 billion, or $3.30 per share, which beat Wall Street expectations for the July-September period... Leading in sales for the quarter was Microsoft's productivity business segment, which includes its Office suite of email and other workplace products, growing 12% to $28.3 billion. Microsoft's cloud-focused business segment grew 20% from the same time last year to $24.1 billion for the three months ending Sept. 30. Its personal computing business, led by its Windows division, grew 17% to $13.2 billion. A big part of that growth came from Microsoft's Xbox video game business, which was boosted by its purchase of game publishing giant Activision Blizzard a year ago.

The Federal Trade Commission is preparing to launch an investigation into anti-competitive practices at Microsoft's cloud computing business, Financial Times reported Thursday, as the US regulator continues to pursue Big Tech in the final weeks of Joe Biden's presidency. From the report: The FTC is examining allegations that Microsoft is abusing its market power in productivity software by imposing punitive licensing terms to prevent customers from moving their data from its Azure cloud service to competitors' platforms, according to people with direct knowledge of the matter.

Tactics being examined include substantially increasing subscription fees for those that leave, charging steep exit fees and allegedly making its Office 365 products incompatible with rival clouds, they added.

An anonymous reader shares a report: After dragging its feet for years, Microsoft has finally released the first official Windows 11 ISOs for PCs with an Arm64 processor. This means users can now clean install Windows 11 using official offline media on an Arm64-based PC, including the latest Snapdragon X Copilot+ PCs.

The ISOs contain version 24H2 can be downloaded from the official Microsoft website, and are around 5GB in size depending on the language you select. According to the company, the ISOs are primarily designed for running Windows 11 in a virtual machine on Arm64 PCs. However, it also mentions that you can use them to clean install Windows 11 directly onto Arm64 hardware too.Unfortunately, depending on the Arm64 PC you have, you may need to do some additional work to get the ISO bootable.

Scientists have developed a method to reuse components from decommissioned data center servers, potentially reducing the carbon footprint of cloud computing infrastructure.

The research team from Microsoft, Carnegie Mellon University and the University of Washington demonstrated that older RAM modules and solid-state drives can be safely repurposed in new server builds without compromising performance, according to papers presented at recent computer architecture conferences.

When combined with energy-efficient processors, the prototype servers achieved an 8% reduction in total carbon emissions during Azure cloud service testing. Researchers estimate the approach could cut global carbon emissions by up to 0.2% if widely adopted. The cloud computing industry currently accounts for 3% of global energy consumption and could represent 20% of emissions by 2030, according to computing experts. Most data centers, including Microsoft's Azure, typically replace servers every 3-5 years.
