I knew there had to be something out there to de-louse dell computers. Too bad I didn't find this a month ago.
My first Dell, I manually removed most of the crud. Must have left fragments, because I got a bunch of errors on every reboot. So I called Dell support with the specific errors. (I do IT Supprot for a living; figured they'd have some instructions specific to Dell pc's, save me time.)
Well, ol' Vinosh, or Guru, or whoever it was, asked me questions I'd just answered several times. Then he unveiled his big solution:
Reinstall Windows XP.
Well, I'd just finished migrating my files and installing all my apps, so I said thanks, hung up, and just figured it out.
Now with the second Dell, I used the Decrapifier. Took a repeat and a couple of tweaks, but it was really sweet.
