How to change product key on Windows 8 Enterprise Edition
I have just installed Windows 8 in dual boot mode on my laptop. During Windows 8 Enterprise Edition installation I had no prompt to enter the product key.
Upon successful installation I was noted that I have to activate my Windows, but unlike Windows 7, I couldn't find an option to change the product key.
Therefore I asked my good friend from Microsoft and I got the following answer.

Run the following command in Run prompt:
The activation page will appear where you can type your new key. Activation should be automatic upon entering the new key.
Open CMD in elevated mode (run as administrator)
Type the following command:
slmgr.vbs -ipk PRODUCT KEY
Replace the PRODUCT KEY with your valid Windows 8 Enterprise key.
After successful message product key will be changed and Windows 8 will be automatically activated.
