A Windows 10 update generated problems for users

Since installing the KB4535996 cumulative update for Windows 10, released by Microsoft at the end of February, Windows 10 1909 and 1903 users reported numerous glitches that appear to have been caused by the update itself.

These included include boot issues, crashes, performance problems, audio issues and broken developer tools. In fact, it reduced performance. The update is also causing SignTool.exe to crash with generic error messages. Microsoft hasn’t issued any warnings for Windows 10 owners. The official workaround is still not available. But on the Microsoft Answers website it has told at least one user to uninstall the update which already was optional.


If you haven't installed it yet, don’t do it ! If you installed the update you can still roll it back. Follow the steps: 1. Go to 'update & security; 2. Go to 'update history'; 3. Hit 'uninstall updates'; 4. Type 'Windows 10 update KB453599' into the search box; 5. Click 'uninstall' and then 'yes' to confirm. The PC will complete the reversal and reboot. After the patch has been removed, open the same page again and pause the update for seven days.
