This one has me stumped. Something I did today caused what can I only assume to be programs that need to run as administrator to fail. Anything with that little shield next to it. Examples: Right clicking on My Computer > Manage wont open but typing manage then clicking on Computer Management from the search will open it. Remote Desktop pinned jump lists (and recent for that matter) will not open. Opening remote desktop and typing in the computer will work perfectly. Making a shortcut FROM the pinned jumplist on the desktop (right click, drag, make shortcut) works. This one is the most annoying as I am frequently remote desktoping into other computers. UAC is turned off and has been up until this error started. I have tired turning it back on, restarting, no go. It has now been turned back off. I have tried logging in as the administrator account, no go. No luck in safe mode either. When this happens, I can see what appears to be a program icon trying to load then it disappears. I'm out of ideas and am close to sticking the disc in and running a re-install but thought i'd try here first. Thoughts anyone?
