Start was "4" and "DelayedAutostart" was "1". I do not wish to reinstall Windows because I have so much stuff on this OS installation that it'd take far too long to put back on. I don't have enough space to make backups of everything either. It's not at all because I've never done it before, on the contrary, many times in the past. One should not be expected to reinstall Windows when they bump into a problem - that is ill advice. EDIT: Everything to do wiht Windows Defender and Security service in registry is disabled and I'm unable to enable or start them.

That's a wild speculation considering Avast is awful. But I've never used Avast on this system so this one is a no.

I've attempted to uninstall MBAM in an attempt at resolving the issue but when no third party AV is installed, I get the same error. I've ran SFC and those DISM restore commands in PS to no avail.

I've followed at least 10 legitimate guides, including Microsoft's guides. They don't resolve the issue, as I said.

Hello people. My OS continues (after a few months) to claim that the "Windows security centre service can't be started". I've Google'd the issue several times, following guides and tutorials to get it working again but to no avail. I'm hoping someone here knows how to resolve this issue without having to suggest reinstallation of Windows.
