How to Change User Account Control in a Registryby Mike Benson
The User Account Control feature included in modern versions of the Windows operating system is designed to allow users to take control of potentially hazardous changes to your computer. When an application needs to make a change to a file or registry entry, the User Account Control will notify you of the situation and request your permission in order to continue. Microsoft provides you with the ability to adjust the sensitivity level of this component. While the easiest way to change this behavior is through Windows Explorer, you are also able to make changes via the registry editor.
Press the "Windows" and "R" keys simultaneously to open a "Run" box.
Type "Regedit" in the "Run" box and click the "OK" button. This opens the Windows Registry Editor.
Navigate to "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System" in the left pane. This will load a list of system policy-related values in the right pane.
Right-click "EnableLUA" in the right pane and click "Modify." This opens a dialog box containing the properties for the selected value.
Change the number in the "Value Data" field from "1" to "0" to disable User Account Control.
