1. Open the Registry Editor by typing “regedit” into the Start menu search box and pressing Enter
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
3. Double-click on EnableLUA and set its value from 1 to 0
This will disable UAC entirely, so only do this if you’re sure you don’t need it. If you’re not sure, leave this setting alone.
