I'm running Windows 10 Pro, and I recently upgraded to build 1803, the Spring Creators Update.
Now there were no issues after updating, except that my Windows Defender is now unusable.
First off the service for it won't run:
And I cannot access the "Virus & Threat Protection" menu in Windows Defender's UI. I have to go to PC Settings --> Update & Security --> Windows Security --> Virus & Threat Protection.
Even if I access it from there, it just brings me to the UI and gives me this error:
Of course when I saw this error I immediately thought "Something in the group policy might've changed" but nope, I checked and the following policy settings are all set to Not Configured:
- Turn off Windows Defender Antivirus
- Allow antimalware service to startup with normal priority
- Enable headless UI mode
I also checked the registry for the "DisableAntiSpyware" value, but it was set to 0. So obviously Defender is not disabled, just unusable for some reason.
I don't know what to do anymore.
I already tried using Tweaking.com's Windows Repair (http://www.tweaking.com/) to reset all service/registry permissions but it didn't work. It just told me "skipping repair".
Help? What else can I do besides reverting? I can't even revert lol, tells me that I can't go back.
(and don't tell me to get another AV solution -- AV solutions nowadays are irrelevant as long as you have common sense. uBlock, Windows Defender and Malwarebytes Free for ocassional scanning is all I need.)
