Finally bit the bullet yesterday and installed XP Pro. Decided not to go for the full clean install and didn't want to upgrade so chose the New Install option. Everything was fine until I started reinstalling software when I realised that the Program Files folder now contained a mixture of new and old files and that I would have to manually remove the old junk. My suggestion for a new tip is to rename the Program Files folder before starting the XP New Install process. I thought I had read up fairly extensively on the do's and don'ts with installing XP but I got caught out and I'm sure I'm not the only one!
