EASY way to DELETE nwwia, xerox, etc.This will give you added power over your Xtremely Pesky operating system. I did the following and have had NO problemsDo a find on 'sfcfiles'. You need to do the advanced search option, and check 'Search system folders', 'Search hidden files', and 'Search sub folders'. Results will be sfcfiles.dll, in one or more places. Change all their names (highlight the file and hit F2) to sfcfilesold.dll. XP may tell you that you are being very very BAD, so tell XP to go piss up a rope...lol........Restart, and voila, you can delete nwwia, xerox etc. source: http://www.annoyances.org/exec/forum/winxp/r1063931130
