Enable / Disable UAC from the Vista Command Prompt
If you have used Windows Vista for more then a couple of minutes, you have probably discovered the UAC (User Access Control) by now. If you are here reading this article, chances are you want to disable the UAC before it drives you mad!
Note: Disabling the UAC will lead to a less secure system – be warned!
Disable UAC
C:\Windows\System32\cmd.exe /k %windir%\System32\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Pol icies\System /v EnableLUA /t REG_DWORD /d 0 /f
Enable UAC
C:\Windows\System32\cmd.exe /k %windir%\System32\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Pol icies\System /v EnableLUA /t REG_DWORD /d 1 /f
After you enable or disable UAC, you will have to reboot your computer for the changes to take effect.
Note: If you don’t want to use the command prompt, I wrote an article some time ago which explains how to Enable/Disable the UAC using the Control Panel. This article can be found here!
