Check or Turn Off Windows UAC (User Account Control)

Windows User Account Control or UAC is another Windows feature that may cause any non-Microsoft application to malfunction.

Deciding whether the security benefit is worth the trouble is your choice.

Here's my preferred way of verifying it:

1- Open Regedit on the machine
2- check the registry key HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\EnableLUA 
(REG_DWORD) if the key is missing or its value is 0, then it's disabled, any other value (like 1) then it's enabled


The way to do it from the UI is as follow:

From your "Start Menu"
Launch the "Control Panel"
Select "User Accounts"
Then "Change User Account Control Settings"

reboot your computer after any change!
