How to Stop UAC from Dimming Screen on Windows 7

The UAC or User Account Control is a security infrastructure that Microsoft has been using since the time when they released the Windows Vista version and carried on in the later operating systems too. Under this option, the authorization by the administrator is required to install a new program or run a new application in the computer which is a very good security feature. Other users who do not have administrative authorization cannot start the application and this also prevents various unwanted activities. This is mainly designed to prevent the attack of Trojan or malware from another program into the operating system.

The User Account Control dims the screen while asking permission for running a new program, and in the middle of the screen, a mini window appears to ask the permission of the administrator and it contains options to run or ignore the program. For some users, the dimming screen is annoying and for them, here is a suggestion to stop the dimming.

The process is different in Windows 7 and Windows Vista. The system of Windows 7 is comparatively easier and you can do it from the Control Panel. In the Control Panel, you will find the User Accounts tab and by opening it, you will get to a list to make changes in your user account. At the last part of the list, you will find the option User Account Control Settings. You can bring down the slider to the point that says “do not dim the desktop” and you are good to go.

If you are using the Business or Ultimate editions of Windows Vista, you need to type the word “security” within the search box of the Start Menu. This will open the “Local Security Policy” option along with some other options. Open the Local Security Policy window and find out the “Local Policy” option and then the “Security Options”. Once this done, look at the right side of the window and there you will be a list of different options. At the bottom of the list, you will find the option “User Account Control: Switch to the secure desktop when prompting for elevation.” You have to open it by double clicking and from the new window; you have to check the Disable option. This will complete the task. You can exit the window after that and you have stopped the problem!

If you are using the Home edition of Windows Vista, the job is little difficult as you have to change a registry value. Changing the registry is very sensitive and one mistake can cause serious problem to your computer. You need to be very careful and follow the instruction accordingly. You can open the registry by typing regedit in the Run of the Start Menu. This will open the registry window. You have to find this key:

[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystem]

You have to create a new 32-bit DWORD by opening the right hand pane and by clicking the right hand button of the mouse. The actual DWORD value is PromptOnSecureDesktop and you have to assign its value to 0. This will solve the dimming problem on your computer.
