Nevermind!–Figured it out 😀
Went to cmd prompt, and used the runas command to launch regedit in the administrator environment and then deleted the DWORD value from there!
In case anyone else has this problem. Launch command prompt from the start menu. Go to your system32 folder (C:WindowsSystem32) and type “runas env user:administrator ‘regedit.exe'” , that way you have full permissions in the Registry Editor and can do what you need to!
