The latest update for Windows 10, KB4556799, is reportedly causing a bunch of issues for many users of Microsoft’s operating system, including a Blue Screen of Death, flickering displays, strange fonts, rolling back to Windows 10S, and audio problems.
Do NOT Shut Down Your Computer! (Here's Why)
Reason to panic? It’s possible that this security update will bring similar problems to you, though one expert told Lifewire that the scope of the problem may be exaggerated.
Not macOS: You might be wondering why Windows continues to have these kinds of problems with updates. One of the things Microsoft has to deal with is a much wider range of hardware and software that is and isn’t compatible with updated code. Apple tends to avoid this problem by maintaining tight control over both its hardware and software, resulting in fewer catastrophic problems following updates (though it’s not entirely problem-free).
Options: If the flood of bad updates is getting you down, you can roll back to the previous Windows 10 version, or you can be more proactive and stop automatic updates altogether. It’s possible that your PC will be fine with the latest update (it doesn’t affect everyone), so there’s no need to worry if you’ve already applied it and everything is going well.
