XP Pro to XP Home Thanks again for all your help about putting a replacement hard drive and OS in the second hand Dell my friend has given me. It seems each solution leads to a new problem! I had hoped to just copy an image of my current XP Home, which is on a PATA drive, to the new SATA hard drive for the Dell. For some reason I had assumed he had XP Home like I do, but he had Profesional. So now, other than the really really time-consuming way, I have four choices that I can think of to get all my data and programs and settings to the new computer, all probably bad, but you tell me! 1) Clone my XP Home to the a SATA drive for the new-to-me Dell computer, and hope that the Dell Product Key on that computer will work for Home even though the computer originally had Pro. End up with Home. If this would work, it would be just fine. 2) Use the Dell XP Pro Reinstallation CD to put barebones Pro in the Dell, a) then use my own retail XPHome CD to *down*grade from Pro to Home. Then copy every file in my current XPHome to the Dell. End up with Pro. If it's possible to downgrade, this would be just fine. OR b) then copy every file from my current XPHome that won't interfere*** with Pro to the Dell. Copy every file I can that is related to me and what I've been doing. On the Dell, reinstall much of the software**, almost all of which I have the setup files for. End up with Pro. Or c) then copy every file from my current XPHome including those which would cause XPPro to become XPHome; copy almost every file. Reinstall whatever needs to be reinstalled. End up with Home. For option b) ***Is it possible that someone has made up instructions how to do this? Or has made a list of what files *would* interefere with Pro? I figure they would all be in the Windows folder, but otoh, I can't make things work if I don't copy a lot of the files in that folder. If this would really work, I'd end up with Pro, which would be nice, but it seems unlikely to work. Or maybe someone has made a list of files that *would* interfere with Pro. Either way. Plus I can make reasonable choices myself, and add more later, or delete/rename ones I shouldn't have have copied. **Except Agent (for news) and Eudora (for mail) and anything else that doesn't need installation. IIUC all the programs I have now should be in the "Program Files" folder, but maybe some are elsewhere, like in the Windows folder???. -- end footnotes for 2b -- Thanks for any helpful suggestions.
