I changed the 'Security Level' in 'Software Restriction Policy' in the 'Local Security Settings' to 'Disallowed', and deleted all the rules under the 'Additional Rules' folder. The result is that nothing can be run, and all system commands are now disabled!
I cannot run anything, including all control panel applications. The error output if i tried to run any system application is as follows:
Windows cannot open this program because it has been prevented by a software restriction policy. For more information, open Event Viewer or contact your system administrator.
and I am running as an administrator.
Is there a way to restore the default settings back from safe mode or anything?
