Wayne Williams, writing for BetaNews: Microsoft pushed out a mysterious driver to Windows users on Wednesday that caused big problems for some. The driver, listed as "Microsoft -- WPD -- 2/22/2016 12:00:00 AM -- 5.2.5326.4762," wasn't accompanied by any details, although we knew from the name that it related to Windows Portable Devices and affected users who had phones and tablets connected to the OS. Microsoft today admitted the problem with the driver, saying on the Answers Forum: "An incorrect device driver was released for Windows 10, on March 8, 2017, that affected a small group of users with connected phones or portable devices. After installation, these devices are not detected properly by Windows 10, but are affected in no other way. We removed the driver from Windows Update the same day, but if the driver had already installed, you may still be having this issue." As Williams adds, even though it was an optional update for Windows 7 and Windows 8.1 users, it was pushed to those on Windows 10.
