On Windows 8 Pro, I'm trying to add Windows Media Center using the Add features to Windows 8 dialog, but when I enter my product key I get the message This key won't work. Check it and try again, or try a different key.

Add features to Windows 8 error

I ditched my cable boxes for Cable cards, so I can't watch TV without Windows Media Center.

How can I install it? Do I need to buy a key for it?

I am going to guess you won't be able Media Center until the GA release of Windows 8 in Oct. You also need to purchase the Media Center add-on, Windows 8 Pro DOES NOT INCLUDE IT, its just the only version eligible to purchase it. Besides....The price of said add-on has not been released, which means you cannot purchase it, and Windows 8 TechNet licenses might not even be eligble to purchase it. – Ramhound Aug 20 '12 at 13:40

Media Center is avaiable for free until Jan 2013, but you have to go to the microsoft website to get a a new key to install it, i.e. you can NOT use your Windows 8 installation key!!

Go to the following Microsoft page, enter your email address and they will email a key to add Media Center.

After patiently waiting for the official launch of Windows 8 for my key to work, I was disappointed to see it didn't.

Fortunately though, until January 31st, 2013, Microsoft is offering the Windows 8 Media Center Pack for free.

If you don't have Windows 8 Pro, or miss the offer deadline, you would have to buy a key by choosing I want to buy a key online. The same website has a deal for the Windows 8 Pro Pack which includes, the Windows 8 Media Center Pack.

The key is public and free


Also look in the FAQ at Microsoft under "Using Windows 8 Release Preview"

Not sure if this applies to RTM versions of W8.

EDIT: reports that this key does not work for RTM versions.

I'm hesitant to try this due to that caveat at the end: "I was told that I must reactivate Windows, and it asked for a new product key. I entered the product key noted above, which worked." – Louis Aug 17 '12 at 3:45
Its on the microsoft site also, this is for Release Preview, not sure what needs to be done if you are using – Moab Aug 17 '12 at 23:46
This key will not work for the RTM build currently available to MSDN/Technet subscribers. – Rowland Shaw Aug 20 '12 at 12:10
@RowlandShaw thanks for the info. – Moab Aug 20 '12 at 13:27
I hate to downvote an answer like this, but because the answer was directed towards the Release Preview version, this answer should simply be deleted. – Ramhound Aug 20 '12 at 13:38
