Yes. Boot your computer from the Pro CD (I assume you know how), and select the option to do a "repair install". Skip creating new accounts at the end of setup, and everything should work just as it did before.

You can ... but unless you need to connect and logon to a server ... you will gain very little benefit from the upgrade
Yup you can do that.

Enjoy!!!
Sure you can, buy the XP Pro retail or upgrade version, pop in the CD and you are off.

Question is more to do with why ? unless you need proper networking, theres really not much point.
u can upgrade.go to microsoft site and click on xp pro.
Yes - but why bother spending the extra money
You can, but the only real reason (I know of) to is to have Internet Information Server or proper integration with a Windows NT Domain. Unless you need ASP you can get other internet servers for less money.

So, you can - but (as other people have said) why bother....
Yes, but you must use an upgrade version to do this.
