Windows 10 users are reporting crashes such as the Blue Screen of Death (BSOD) after installing the April 14 update, also known as KB4549951.
Windows 10 update is breaking your PC
The details: As reported on BetaNews, some people are saying that the two-week-old update has caused issues with Bluetooth and Wi-Fi, along with reduced performance. Other users complained of settings being reset, files being sent to the Recycle Bin, and some noted that files were disappearing altogether.
If you're affected: The update applies to two specific Windows 10 installations: 1903-OS Build 18362.778 and 1909-OS Build 18363.778. If you have one of these builds (run winver in the search box or a Command Prompt window to see) and have not yet updated, you can disable automatic updates until Microsoft releases a fix. You can also uninstall the update, if necessary.
In short: This isn’t the first problem with a Windows 10 update, and it likely won’t be the last. Microsoft should release an updated fix for the problem at some point, even if that means we have to wait until the next scheduled update release in May.
