Disable UAC on server 2012

To really turn UAC off

Go to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system and set EnableLUA to 0.

Or run this to get current value (will be 0x1 if it's enabled)

REG QUERY HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system /v EnableLUA

To disable it (will prompt to overwrite)

REG ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system /v EnableLUA /t REG_DWORD /d 0
