For some reason, my logon background image isnt showing up anymore, and when I try to change back to the way I had done it, regedit wont run, I've searched the forums for an answer, with no luck. And when I go to click grant admin full control, it brings up an open with menu, so I need a command script to grant admin to certain files again.
Windows 7 home premium 64 bit.
Please help, and thanks. And no, I dont have any viruses or malware, I take good care of my computer.
