Maybe I am set in my ways, but if an OS, any OS, makes me have to approve each and every action I take than I will not use it. I circumvented this by using the hidden admin account in Vista and Win7 but the Win8 Preview took that away by making the admin account local only. If/when I find a way to set this up the way i want it I may give it another shot, but not until then.
Open up Run. Type in secpol.msc and let that Windows Open. Go under Local Policies>Security Options. User Account Control: Behavior of the elevation prompts>Set to Elevate without Prompting. Problem solved.
Same steps I have listed in the Admin Rights topic for Vista/Win7 as well.
