I am using Windows 10, and today (2021-01-28) I got a BSoD, the computer then rebooted automatically, and after reboot, sound, microphone and camera weren't working on the system;
Windows Defender disappeared, and I couldn't run
cmd as admin (my account is the only account and it's an administrator account).
The last update was indeed installed today as shown by the update history:
Security Intelligence Update for Microsoft Windows Defender Antivirus - Update KB2267602 (Version 1.329.3006.0)
Device manager showed that all device drivers were detected and up to date, I went to safe mode and ran:
It found and repaired corrupt files, I then went back into normal mode, managed to launch
cmd as admin with: Win+R>>type
sfc /scannow again, and it did not find any other problems.
Windows Audio service couldn't be started even if I tried to start it in
services.msc it gave me:
Error 0x80070005: Access is denied.
I have a restore point created 1 week ago. Is this the only option? How can I uninstall this last KB update?
I am sadly no expert, sorry If the question is vague, I could give more information.
Any help is appreciated. Even if it's just teaching how to get thte log of the BSoD.
