Stupid windows

I tried going to my user accounts in my control panel and a window pops up but its completely blank, not only that but when I tried to use the search function, nothing pops up at all for that. Would anyone happen to know a solution for this?

Looks like a DLL/registered control problem. I don't know of a proper solution, so consider these things which may help at your risk: Try system repair from the original CD, or install the latest service pack. As a last resort, uninstall the latest service pack and install it again.
