Not true in Win 7. I have had the same problem. and haven't solved it yet myself. I have 2 hard drives. One is my old XP drive and the new is Win 7. I have everything ready to go on Win 7 except my mail. I keep most of my mail, about 2 gigs worth. My friends and family and business correspondence. I have Office 2007 Enterprise and use Outlook. I cannot copy, move, or do anything to the old mail to get it recognized by Win 7 without being the admin. I have a password, I have been in safe mode, I have taken ownership of the files, the folder, the everything to do everything with it, and still cannot move the file. I have even tried the file transfer thingy with Windows and can't do it. I hate to copy 40 gigs of stuff just for my mail. All of this and I can get a virus that infects everthing from someone without any password, rights, ownership, nothing! Gates is a genius.
Just think what it would be like if MS owned GM! But a copy of Linux puppy should enable you to move them. Boot from CD
