I had problem with denied access to a program.
Tried to edit users to allow access
Then I denied system access now I have no access to most of the programs even internet
Here is the path I took that caused the problem
Right click a program properties security highlighted "SYSTEM" Edit Deny  

At this point "Window security" pop up. I thought if it did not fix my problem I could go back in and select "Allow" to undo.
Well now I am denied access to almost everything
I can't even do a system restore
