Windows 10 optional KB4535996 new Bug: system crash, login interface blue screen

If you manually check for updates and install the optional February update patch, you may encounter system crashes and other problems, including errors that cause the video card to disappear. According to user reports, the Windows 10 KB4535996 patch crashes some computers and also causes performance problems.

The Windows 10 KB4535996 patch is an optional update that is installed only when users download it manually, but it has created a series of other problems. For example, users previously reported that the patch caused a drop in the FPS frame rate in some games, audio stutters with some sound adapters, and blue screen panic (BSOD).

According to the latest report, the KB4535996 patch can cause the system to crash and lock the device with a blue screen on the login page.

One user said, "you cannot enter any safe mode and uninstall this update. Force a restart, and GPO blocks this particular update. Microsoft says they haven't heard of any problems. However, when you search the Internet, this optional update alone will cause a lot of problems."

In the feedback Center, Windows 10 users reported a series of problems. For some patches, it can also cause high CPU usage and file explorer crashes, while other patches report shutdown and sleep problems.

Microsoft has not confirmed any reported problems in its forums and feedback centers. The Windows support documentation still says, "Microsoft is not aware of any problems with this update."
