In case anyone is curious, I performed the upgrade on Friday and it went off without a hitch. I applied XP SP1 afterwards and everything looks great - none of my settings or files were affected at all. Thanks for the help!
I bought a new Dell Dimension that came pre-installed with XP Home. I own a legal CD-ROM of the full version of XP Professional and would like to upgrade. Can I use the full XP Professional CD-ROM to perform an upgrade of an existing XP Home install or will it automatically do a "clean"...
