I was very surprised at having no problems with my XP install. I never did get a single error.
But the HORROR! The first time the OS came up, I knew what I had to do. Frst thing was to remove all of that ugly default GUI and return to classic mode. Then I removed all of the files associated with them. Thn I went to work on the supposedly unremovable apps, gone. Next it was off to the OS tweaks. I tweaked this sucker with everyone I could find and only succeeded in speeding it up a little. I got the install down from 970+ megs to 475, and still no speed up.
Final mission. The removal of XP.
