I ran Spybot and after it found it's ton of problems I went ahead and "Fixed them". Some of course needed to wait till the next boot to finish the job. That next boot never came as whenever it tries to load windows it hangs up after most of the boot sequence with the cursor blinking in the corner.
An attempt to boot up in safe mode gets to windows just far enough to show the wall paper and an error message that Explorer caused an error in Explorer.exe yadda yadda a bunch of registry info yadda yadda something about EAX and some other stuff about a page fault.
I DID the "backup of registry" in the beginning of the Spybot session. Can I recover that from a dos command line? The command line only mode seems to be the only successful boot I can do.
