Windows 10: Can't activate Windows Defender. Windows 10 Home

This problem is getting on my nerves, and I am also afraid that I might be infected with something on my PC.
So, I cannot turn on Real Time Protection, so basically I don't have any form of protection overall, I cannot perform any scan, and when I click ''Protection History, it crashes. It also says that ''This setting is managed by your administrator'', but I am the only user, and the admin of the computer.

When I've encountered this, I had Avast installed, but usually I could've used Defender in the same time, now it doesn't even show Avast and Malwarebytes in the ''Manage Providers'' tab. I did various scans with these 2 engines, and also CCleaner, which found many broken registry items and stuff like that, which were, deleted, and trojans - quarantined, but the problem is still there.

I've also tried to do the methods using the cmd prompt, nothing, I tried the Registry Editor method, deleted ''DisableAntiSpyWare'', nothing.


Previous problems that I've had yesterday may be linked to this: I couldn't put my PC in Sleep, I couldn't update Windows, I've solved those, I have no idea how, I don't even remember, I am losing my mind. Please help

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK
