How do I enable or disable UAC from a batch file?

I go through phases on my Windows Vista machine where I am OK with using UAC and other times where I just want it to go away for a while. I compare it to staring at a computer screen for hours. It is nice to take a break and get a hot cup of coffee or grab a Tall mocha from Starbucks.

The command-line entries to enable and disable are the following:

• Enable UAC:
  

  C:\Windows\System32\cmd.exe /k %windir%\System32\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 1 /f

• Disable UAC:

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

I created the following two batch files available for download:

• Download Enable UAC
  
• Download Disable UAC

Follow these steps to enable or disable UAC. After downloading and extracting the two zip files, right-click on one of them and choose Run as Administrator. In this example I will enable UAC (Figure A).

When you enable UAC, a reboot (Figure B) is required.

Alternatively, you can accomplish the same task by typing User Accounts (Figure C) in the Instant Search field.

Next, select Turn User Account Control On or Off (Figure D) and then tick the checkbox to enable UAC.
