I was partially mistaken.
I installed XP in a VMware VM, and did some fiddling(what you thought I'd partition?). Anyhow, yes you can follow those steps to 'remove' IE. But as has been previously said, it simply hides it, it was still eating up 30megs of space in it's folder. And it was still usable! Aparently the registry was left untouched by the 'uninstaller'.
Oh well. After that I deleted the virtual disk I had it one, and went back to doind my useless stuff.
Oh and when I had XP installed on a real partition(a few months back), I saw a couple of blue screens, exactly like the NT blue screen. And XP also reset all by itself sometimes. It reset once when hooked up my slve drive. The drive worked in everything else perfectly(WinME, and Mandrake), but XP reset, apparently XP didn't know how to install the drivers and crashed. The only way I solved the problem was to reinstall XP.
