If you are tired of waiting for a dimmed screen and answering Yes in some unwanted dialogs, then you should disable UAC and enable “Always run as administrator”. Windows built-in inteface does not provide a way to do it. You have to execute the following registry change:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system]
"EnableLUA"=dword:00000000


Download and execute the registry change
