Cumulative update KB4103721 caused problems on the computers of some users of Windows 10 April 2018 Update. It was released last Tuesday (8) to fix bugs found after installing the latest operating system update, such as the "blue screen" and Google Chrome freeze. After restarting the PC to complete the upgrade, a black screen is displayed to the user, making the computer unusable.
If you have not installed the update yet, the recommendation is to wait - see, at the end of the text, how to hide an update in Windows 10 to postpone it until Microsoft offers a solution to the bug. If you have already installed the update and are experiencing the problem, check out two ways to uninstall and restore your PC.
