I have a 200GB HD with XP home, with over half of that space being used. I'm backing up important files so that I can format the HD and install XP Pro 32bit.

1. Should I format the HD before I do this?

2. If I backup my iTunes library, will I be able to get it back when XP Pro is installed?

3. Should I just keep XP home?

I also have a 320GB HD that I plan on putting Vista Ultimate on. I think the only reason I want to format the 200 and install XP Pro is because the XP Pro was free and that 200GB has become cluttered and I think it needs formatted to help with performance. So let me know what you think.

Thanks.

Unless you're planning on joining a Windows Domain, there's no advantage to XP Pro.

Will formatting and reinstalling XP home increase performance?

Well, cleaner systems tend to run faster. Without proper maintenance, Windows has the habit of "slowing down" over time.

Just copy the contents of your I-tunes so when you format you acan copy and paste over the new folders.

The main reason for XP Pro I believe is for remote access. Other than that not sure why you would want to switch.
