I've got this same problem. I haven't done anything besides install windows, and yeah, it's definately pre SP1, I probably bought the CD 5 years ago. Going to search Google, but thought I'd ask here. Does anybody know exactly what order of steps should be taken? Should I just go run all the windows updates and when I get SP2 on just merge the whole thing together, or should I just wipe the windows installation, reformat, and start over using a program to partition the whole 500 GB together, then install windows again?
