Windows Vista uses a feature called User Account Control or UAC to limit the privileges of regular user accounts. UAC ensures that all user accounts that are not part of the local administrators group run with no administrative privileges. This feature is enabled by default. However, in some situations you may want to disable it and there are multiple ways that you can accomplish this. One method is by using Group Policy.

To disable UAC using Group Policy:

1. Click Start and click Run.

2. Type gpedit.msc and click OK. This will open the Group Policy Editor.
3. Browse to Computer Configuration | Windows Settings | Security Settings | Local Policies | Security Options.
4. In the details pane, locate the User Access Control policies.
5. Right click each of the following policies and change the value as indicated below:
   • User Account Control: Detect application installations and prompt for elevation - Disabled

   • User Account Control: Behavior of the elevation prompt for standard users - No prompt
   • User Account Control: Run all administrators in Admin Approval Mode - Disabled

Close the Group Policy Editor window. You can enable UAC again by changing the policies above to their default values.
