Disabling UAC

There are to easy ways to disable the secure but annoying UAC (User Account Control) in Windows 2008 (R2 or not) or Windows Vista.

The simpler one is to use reg.exe at the command prompt. Just run the following command at the DOS prompt on one line:

%windir%\System32\cmd.exe /k %windir%\System32\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0 /f

You need to reboot the computer for changes to apply
This should also work on Windows 7 even if I have not tested it yet.

The second way is to disable UAC from MSCONFIG, which is a standard Microsoft utility to troubleshoot the Windows startup process.
  • Press Windows + R keyboard shortcut to bring up the Run command dialog box
  • Type msconfig and press OK button
  • Click on the Tools tab
  • Find and highlight the Disable UAC or Enable UAC tool
  • Click on the Launch button.
In this case also you must reboot the computer for changes to apply.

Note that you can re-enable UAC by selecting Enable UAC and then pressing the Launch button.

If you fell less confident in modifying your system parameters, then refer to TweakUAC which is a freeware software tool that you can use to quickly turn UAC on or off, or to make it operate in the quiet mode.


  1. Wow, that's a lot easier than I thought it would be! I was picturing something out of Indiana Jones and the Temple of Doom!

    Thanks for writing this (and thanks for linking to Standalone Sysadmin!)
