WinXP Pro maturing in less than 30 days [anyone else having this problem] [winme]

Q: Anyone else with this problem? I installed WinXP Pro v2600 a while ago [upgraded from WinME] and it is too early end. I would expect this from the HOME version and not PRO.

WinXP Home OEM full version can be used to upgrade? [winme] [newegg]

Q: Folks, I just bought an OEM version of WinXP Home full version from Newegg for a friend in hopes of using it to upgrade his system. Can this be used to upgrade WinME without losing files and / or data, and how can I do? Every time I try to start nothing is shown about upgrading, but loading WinXP. Am I doing something wrong or should I try something that not possible? Any help would be greatly appreciated. Thanks people.;)
