Ever since I upgraded to windows 10, when turning on my PC, windows defender has been popping up saying that it has been turned off and not monitoring my computer. I'm aware that this happens when there is a conflicting antivirus on the PC but I haven't installed one. I've tried going into the services and starting it manually, but it just says "Windows could not start the Windows Defender Service on Local Computer. Error 577."

I even tried going into the registry and changing the "DisableAntiVirus and DisableAntiSpyware" values to 0, which works for about 30 seconds after a pc restart, but then it flips back to 1 and stops it again. Since then I've run numerous antivirus and anti malware/adware programs and they all have come up negative, so it isn't a virus either.

I have officially run out of ideas. I would just forget about defender and move on to a different program, but the popup will still display every time I turn on my PC. Any help would be greatly appreciated!!
