I'm running Windows 7 64 bit. Following a recent restart, windows would load to a white desktop (or black in safemode) and a missing taskbar. The desktop, apart from being completely white, can't be interacted with (no drag and pull boxes). The taskbar is gone and the windows key won't bring up the start menu.
I can still access the task manager and have used that to navigate through my documents and to access my web browser (hence my being here now). Because I can still access and run everything through the task manager and command window, I haven't lost any utility, but I'd like my taskbar and desktop back.
