I just recently installed Windows 8 on my home computer. During the installation process, I was not asked to provide a product key. This led to me not being able to activate Windows after the installation process.
To resolve this, follow these steps:
cmd
Command Prompt
and select Run as Administrator
slmgr -upk
Windows+C
to bring up the Charms windowSettings
and click Change PC Settings
Activate Windows
tab will now ask you for your product keyOddly enough, I had trouble finding this info so I thought I’d share.
