    If you are so bent on having the pro features and are willing to copy all the files off the CD, hack it, and then re-burn it (not to mention making sure not to screw up the bootable ability of the CD), why not just download Windows XP Pro? Both are illegal(take a look at the EULA), and downloading is easier and will still allow you to upgrade to SP2.

      It's not like it's easier on Adobe to make differerent, variously crippled versions of Photoshop. It's actually more work. They do it because it works for their shareholders: you sell a basic version with features disabled for $x, and make users pay for more features. Yeah, it's the same cost to them to print a CD either way, but the price of things is ALWAYS set by what people are willing to pay, not by what it costs you to make.

      At least in the non-free software world. Rather different economics there.
  • ...now if only MS released XP on CD-RW so I could make those changes without sacrificing the bootability of the CD. (e.g. the reason I have an XP CD on my desk almost constantly.)
    • You can still make it bootable. You need to use the -N option to mkisofs (or equivalent) since the loader can't find the kernel on a standards-compliant iso9660 filesystem, but other than that it's a pretty normal bootable cd.

    Hey, another slashdot dupe. I read the same article and almost identical comments 7 years ago when someone realized you could change NT 4 Workstation to NT 4 Server by changing a registry entry and rebooting...

    Tiered versions are extremely common in the commercial software industry. Customers don't want to pay for features they don't want, while other customers will pay extra for features they demand.

    When it is done correctly, it uses the same codebase. The fact that you're able to hack the versioning is completely meaningless.

      Remote Desktop is also much speedier. Even with the latest, greatest, fastest version of VNC, Remote Desktop is still much more responsive. On Windows XP, you can even use a certain file from an old Service Pack 2 beta and support multiple remote users on the same machine.

      and the eaiest way I've found to avoid getting "crap" is to not run as administrator. *poof*, no more problems. I'm surprised more people haven't figured that out yet.

        RDP has advantages over VNC but VNC has come a long way and has nice features like File Transfer, Chat, decent speed, a bunch of different viewer, multiplatform support, and also an encryption plugin. So point out what VNC is missing and I'll do the same for RDP.

    • Don't think it would come under false advertising as "home" and "pro" don't really imply anything as to regards to what it contains like V6 and V8 would.

      Besides, a lot of graphics card manufacturers do this anyway (fairly openly too I think?), as did Intel with the 386SX and 386DX chips I believe. If it was a false advertising issue it probably would have came up by now.

      The former only became illegal when the DMCA was passed. The DMCA makes a lot of previously legal and still necessary actions illegal, so the fact that it's illegal under the DMCA is by itself irrelevant to the morality of the act. So it comes down to the morality of boosting the performance of a factory-crippled product. You can buy products for doing that at any auto-parts store.

  • after all, Microsoft did that with NT Server and NT Workstation. Andrew Schulman had shown that with a few registry tweaks, NT Workstation could be turned into NT Server quite a long time ago. It even fooled server programs like MS SQL Server, Exchange, SNA Server, etc that they were running on NT Server. The only big difference were the support files found on NT Server that NT Workstation did not have.

    If someone looks at it hard enough, they can find registry tweaks to turn XP Starter Edition into a non-crippled version. It might resemble XP Home then. Then apply the XP Home tweaks to turn it into an XP Pro Lite type OS.

    When you think about it, Microsoft keeps the kernels the same, but makes changes to the registry and support files. Tweak the registry, and you may be able to overcome limitations.

    The IP connection limit is built into the TCP/IP stack of XP, but most P2P networks have a modified version that allows the user set their own number of connections, like say 100. I am sure that is against the EULA, but people run it anyway.

    The more crippled Microsoft makes an OS, the more people will discover or find or invent a way around the crippling. Take DRM for example, people have already found ways around it, the new DRM on an Intel chip just makes it more of a challenge for people to find a way around it. Most likely someone will find or invent a way to fool the DRM functions that files are legit, via software or something.

    Microsoft refuses to understand that it must meet the customers' needs, and that making a system more complex or trying to lock it down more, only upsets the customer. They will either seek underground methods to get around the limitations, find an alternative, use an older version of software/hardware, or just learn to suffer with it. In any case, it causes Microsoft bad PR, and a bad reputation.
