Windows 7's installation shouldn't cause such an issue, though it is not impossible. When that happens, try pressing Ctrl + Shift + Esc to view the Task Manager, switch to the Processes tab, and End Task on every instance of Explorer.exe listed. Give it a moment, then go File->New Task and type explorer.exe in. Not a solution, but it may restore Explorer so you can navigate more easily and will help determine if Explorer is corrupt or just glitching at boot.
I hope this is the right topic. I have a

So I just installed windows 7 on my computer on the partition above and when I boot into windows XP, right after I type my password, I just get my desktop background. It seems like it is a problem with explorer because the desktop or any other applications don't come up. Any ideas?
