I changed permissions on all files on C: drive now I get black screen
Windows 10
In Windows Explorer, I right-clicked on C: and went to Properties and then selected the Security tab and edited the permissions to Allow Full control and it ran for a long, long time. When I re-booted the computer it works fine until after the Sign In screen then the screen goes black. I have a cursor and if I hit Ctrl-Atl-Delete I can select Task Manager but then the screen goes black again. I can boot into Safe Mode with Networking and I can get a Command Prompt in Safe Mode. I have looked at ICACLS but I'm not sure how to use it to re-set the permissions back to normal Windows 10 settings.
Anybody have any ideas?
