The OEM bit is the worrying bit for me though, as the CD key they provide is only a one off install isn't it? (i.e. OS installed at Dell - being the one time use only of that key) hence not allowing you to reuse the key which is stuck onto the OS disc. I take it this is the case with XP... (I kinda prefer XP to vista) as vista just recognises the hardware signature that is linked to the key when it is first installed.
or have I just got that completely all wrong?![]()
I've used OEMs all my PC life - it's not a "one shot" install. You can use it as many times as you like. The OEM licence is exactly the same as a full retail boxed licence - the only difference is the OEM licence is supposed to be supplied with hardware.
If what you were saying was true, you'd need to buy a new copy of windows every time you reformatted... madness!!!
