thanks man! it's very strange if you ask me.... it won't authenticate any CD-KEY on my laptop Not the one I bought from the store, neither the OEM CD I got from the manufacturer. BTW, I haven't gotten down to making an unattended install just yet... On Pro I tried slipstreaming the SP2 on the install and the OEM original cd will do the same thing! I can't install Windows and I got a VB exercise to hand in tonight! HEEEEELP! About the patch: can I slipstream it onto a CD? If not what do I do with it? Thanks in advance!
