I did for the first time tonight on an old XP system that I have a Craigslist ad for in the NY area. It said it would take a significant amount of time to do and it wasn’t kidding! With a 140 GB drive it said it will take 15 hours! So I am letting it do that now.
If I can’t find anyone who wants it, I guess I will keep it as a spare. It seems a waste to me to throw a computer away that is perfectly functional. Perhaps I could find a charity who could use an XP machine.
I have rescued old systems in past places I have worked and given them to friend and charities. I know computers can be slow, but they are still very useful tools.
