Sorry for the delay in responding...got a little busy.
Furball146 - I don't really recall the differences between XP Home and Pro, but since my daughter needs to use this laptop for remote access to her work computer, as well as personal e-mail and web surfing, I just thought that Pro might be a better fit for her. Since I already own a legal copy of XP Pro that I can legally install on her laptop, I figured why not. Don't really know what I actually gained for her.
mag - I found nLite XP and used it to create an XP Pro SP3 install. Worked great and the system shows it's running XP Pro with SP3. Had to do a little searching to find an instruction on how to do it, but other than that, no big deal.
One oddity though. When the upgrade finished the hard drive led flashed for a long time, and, while the HD was still flashing, I got the message that I had to activate the installation. Every time I tried, I got a message that I couldn't because some activation module couldn't be found. In fact, any time I tried to access the inernet, any site, I got the same message. Then I got busy and didn't get to look at it again till last night.
I booted it up and and got the same thing. I tried the activation again, but got the same results. Meanwhile the HD was still flashing like crazy, so I just let it sit and do it's thing. Eventually Windows Update came up and downloaded 107 updates - don't think I turned Automatic Updates on yet. After the updates installed, I was able to activate Windows and now everything works fine.
Thanks for the nLite tip. Won't forget that one.
