I am asking this because I have loaded XP Home with different SP's onto systems using the COA on the case and as long as its the same XP HOME or XP PRO etc (i know they have different prod. ID's but so do the Services Pack's) it will take the COA. The SP's don't seem to matter with some series. The answer didn't really help but I will give points just because no one else answered. <br />
<br />
Thanks for the response!

Servie pack shouldnt matter at all, as it is the Product ID that governs how the keys are matched up. OEM discs cant take retail keys, and vice versa.....<br />

I need to reload a Compaq Presario SR2023. It has XP Media CTR 2005. But I do not have the Media Center 2005 edition, but I have HP XP PRO SP1a CD. I need to know if this maching will take this CD and let me use the COA that is on the Compaq? I don't want to even try to reload this if I can't use the HP XP Pro SP1a. I also have a HP XP Home SP2 CD that I can use if I need to. <br />
Thanks for your help.
