Yes you can upgrade from me.
http://www.microsoft.com/windowsxp/pro/how...ding/matrix.aspBut it is not recommended doing to. The reason is because you are going from one OS architecture (a bad one at that) to another. Which can be painful for you applications. And some will need to be reinstalled any ways.
-It is best that you backup all your user data on to a CD/DVD or another computer.
-Download the SP for XP and put that on a CD/DVD or another computer.
http://www.microsoft.com/windowsxp/pro/dow...sp1/sp1lang.asp-Once you have every thing backed up, pop the XP Pro Upgrade CD in the drive, reboot and assuming your computer can boot from cd the XP installer will load.
-It will probably ask you if you want to upgrade or do a complete install. It is recommended to do a complete install cus then your have a "clean" computer and its not loaded down with old unused stuff any more.
-tell it to format your hard drive
BUT make sure you have all your data backed up first!!!!
-Once it is installed make sure your not connected to the internet incase of virus infections and install the SP and install any virus software and firewall software you have.
-Then you can connect to the internet and update your XP and virus software.
