the key might be slightly different. And the fact that you are bassing that on the return of a VBS script is pretty sad. Do it by hand. If you need another tool, then download a tool called reg.exe from Microsoft. it's a query tool from NT4 days. You run something like reg.exe query HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System
and it will return the values in that key. Then you do an export to a .reg file and edit the dword value from 1 to 0.
it's very simple to do.
Don't give up after 1 try. You have to have more stubbornness than that.
if you need more help, I'll keep an eye out.
