Any way to find out the type of Windows your CD key is?

[Skeeter]

Hi there

I recently purchased a second hand laptop (Dell). Having looked at it ive discovered the CD key that is installed on the machine does not match the CD key on the Windows sticker on the base? Firstly, is this normal for Dell installations? But if not, is there any way I can find out what the version of XP is that the installed key of for (Retail, OEM, Corporate, etc). It appears to be a fully legal version... (Passes WGA). I just want to know what key I should use should I reinstal Windows?

Cheers

Yeah I used MagicJellyBean t get my XP Key. What I need to know is:

Is the Key on the sticker on the laptop a Dell only Key, or is the one currently installed a Dell only key? Could either be used on a different machine?
