To check to see whether your computer has activated properly, there is a simple way to do this using a single command at the Run prompt. This screen tells you the operating system and the edition, it also tells you what type of license you have such as a Volume License or Multiple Activation key or a standard retail copy, gives part of the product key for your verification and the status of the activation.

Figure 1: Click START, type slmgr.vbs -dli and hit ENTER then wait
1) Click START, type slmgr.vbs -dli in the searchbox and hit ENTER
Important thing is to wait now, it can take aprox 10 to 20 seconds before you will see the result window. It looks like Vista isn't doing anything, just wait it'll have to check.
