My customer purchased Windows 8 and only Windows 8 Pro has the capability to join to the domain.

Windows 7 had an upgrade key which you can purchase at any store and you can upgrade Windows 7 Home to Pro.

I couldn't find anywhere if it's possible to upgrade a machine with Windows 8 to Windows 8 Pro.

I would like to know if there is any place you can purchase a key to upgrade it.

The "official" answer is to buy the "Windows Pro Pack Upgrade", which includes Media Center.

This is available in many places, including Amazon, etc.

Unfortunately, this is currently retailing for $66.99, or about $20 more than the "Windows 8 Pro Upgrade" that is designed for upgrading XP/Vista/7, and which comes with the ability to obtain a 'Free' license key for the Media Center upgrade.

I would expect that this (Windows 8 Pro Upgrade) could be used to upgrade "Windows 8", but have not tested this.
