Question : Changing Registry Permissions with SubInACL.exe

Apparently the winexit.scr screen saver doesn't work for users.

http://support.microsoft.com/?kbid=156677

I need to go in and change the registry key permissions.

Manually, this is a no-goer, but I could run a special one-time only script to do it. Apparently, I need to use some software called SubInACL.exe

Can anyone please provide some simple instrutions as to how I might write this script?  

Thanks

Answer : Changing Registry Permissions with SubInACL.exe

Are you sure you're looking under "Windows NT", and not "Windows"?
Anyway, that would be these two commands (you can copy and paste them into a .bat or .cmd file):
subinacl /subkeyreg "HKEY_Local_Machine\Software\Microsoft\Windows NT\CurrentVersion\IniFileMappings\Control.ini" /grant=Everyone=S
subinacl /subkeyreg "HKEY_Local_Machine\Software\Microsoft\Windows NT\CurrentVersion\IniFileMappings\Control.ini" /grant=Everyone=C
S is "Set Value", C is "Create Subkey"

.bat are batch files that can run in DOS/Win9x as well; .cmd are batch files that will only be recognized by NT based OSs. You should use the .cmd extension when using commands that don't exist in DOS; NT will run them in .bat files as well, though, but it's better practice to use .cmd for NT specific batch files.
