The latest update March 14, 2023—KB5023696 (OS Builds 19042.2728, 19044.2728, and 19045.2728) - Microsoft Support
completely ruined my software.
Here are the problems I ran into :
First, my Firefox browser just stopped being able to start. I would restart it, and it would freeze seconds after starting. Safe-mode didn't help, resetting didn't help.
My AV freezes mid-scan, and refuses to continue scanning.
A driver installation froze mid-installation, and refused to continue installing.
Every time I try to turn off my computer, it would refuse to shut down, until I force closed 2 "Windows Task Host" processes.
I had to reset my Windows installation, twice, to finally figure out it was the update that was creating the problem.
Please fix this as soon as possible. I have paused updates for 7 days.
