I upgraded Parallels 3.0, to 4.0, then 5.0 for my Windows partition with XP Home. Have had the use of Windows on the iMac during the transition to Apple and its programming, and now am no longer in need the use of any Windows software and am looking at removing all traces and the side of shared files. I originally allocated 100GB of space for Windows and would like a safe way to remove everything. I have been slowly eliminating seldom used program software, but am concerned at correct procedures for taking it all off my iMac. Any help would be much appreciated.
