Hello everyone,So I bought myself the MCITP self-paced training kit series and along with it came the trial CD, but when I try to activate the OS is asks me for a product key...? So where do I get it? Thanks.

This is a trial copy of the software - you don't need to activate it. It comes with the ability to run fine for a period of time (60 days) without any problem, and then you can extend the trial period forup to 240days by use of the slmgr command when it reaches the end initial trial period.
