Change Windows 7 Theme when Group Policy is applied

Just a quick entry to work around the old high contrast issue in Windows 7.

Users can normally apply it but can't revert it back when group policy is locking it down.

Open a command prompt as admin and run the following - the blue can be edited accordingly.  You may need the admin password but if you're an admin needing this for helpdesk reasons that shouldn't be an issue.

rundll32.exe %SystemRoot%\system32\shell32.dll,Control_RunDLL %SystemRoot%\system32\desk.cpl desk,@Themes /Action:OpenTheme /file:"C:\Windows\Resources\Themes\aero.theme"
