Windows 10 blocks almost all of my programs

Without any apparent reason, Windows started blocking pretty much all of my programs. I could understand if it blocked programs like Cheat Engine (which it does), but Word, Excel, sometimes even Chrome!?

By the way, it doesn't matter if the program is running or not. Whenever Windows feels like it, it kills the process.

The worst thing is that I don't get any information from the pop-ups. No description except "Contact your system administrator for more information.".

Help? Thanks.

Hey DeBedenHasen,
If you running latest Win10 (1709), check if Controlled Folder Access is turn on. See this tutorial - Change Windows Defender Controlled Folder Access Settings - Windows 10 Security System Tutorials

Thanks for the link, gonna check it out. But just to tell you something, Windows Defender is completely off! I disabled it using gpedit.

EDIT: Now, after checking I saw that there was nothing I could do there except re-activate WD and enable Periodic Scanning​. What now?
