Answer 2

My Action Center won't open today after Windows installed:

1. September 8, 2020-KB4576478 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 Version 2004
2. September 8, 2020—KB4571756 (OS Build 19041.508)

Is anyone else having this issue or knows how to fix it? I've tried Chkdsk, Sfc, restarting Windows Explorer, and disabling and reenabling Action Center. I can't rename the Usrclass.dat file because it is in use.

OS Name: Microsoft Windows 10 Pro - 64 bit

Version 10.0.19041 Build 19041

Thanks in advance.

Answer 4

Yes I did attempt to roll back to the previous update. Ir was ths first thing I tried.

Running my repair drive did nothing for it. So I did a factory reset.

Hope in doing that you didn't lose too much of your data.  This is all getting past absurd!  Enjoy your "new" computer.

Answer 5

My Antivirus said that this update KB4574727  had a Trojan in it so it is in Quarantine. i have Bitdefender Total Security. I am going to unistall the update because i'm not sure what else to do. There was also another update KB4576484 and i will unistall that one as well just in case.

The file \Device\HarddiskVolume4\WINDOWS\SoftwareDistribution\Download\021b4073b65a625a58c006858ea0a97d\Windows10.0-KB4574727-x64.cab is infected with Trojan.Ciusky.Gen.13. The threat has been successfully blocked, your device is safe.

Likely a false positive. Have you reached out to BD support for any known issue?
