Error messages when taking ownership or changing permissions in C:\
I created a Guest account in Windows 10 and I wanted to restrict its access to my other drives/partitions. I managed to do it for my other drives via security/permission settings, but I'm encountering a bunch of error messages such as "failed to enumerate objects" or "file in use" when I do it on my c:\ (system) drive.
I've tried taking ownership of c:\ and giving my Admin account full control but when I do it gives me the same error messages (example of files that give me this error message are hiberfil.sys, bootmgr, programdata folder, system32 folder, avast, etc.)
My OS becomes unstable after this such as I can't use the search bar, start button not working, etc. Luckily I've created images and restore points before attempting any of this so I was able to revert everything back to normal during my numerous failed attempts.
I've read an old post in the forum with the same issue here: I have broken W 10 by trying to take ownership of C:\ please help! - Windows 10 Forums
Can anybody point me in the right direction on how I can properly do this? Or is it even advisable to try to change permissions or take ownership of c:\?
