I have recently upgraded from Windows 7 to W8, and also installed Windows Media Centre (free till 31 January), using the product key that Microsoft e-mailed me. WMC seems to work fine at the moment.

However, those awfully nice chaps at Microsoft have e-mailed me to say:

**This is a reminder that you must activate your free Windows 8 Media Center Pack product key by January 31, 2013: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX Follow these steps to add Windows 8 Media Center Pack to your PC running Windows 8 Pro: 1. Swipe in from the right edge of the screen, and then tap Search. (If you’re using a mouse, point to the upper-right corner of the screen, and then click Search). 2. Enter add features in the search box, and then tap or click Settings. 3. Tap or click Add features to Windows 8. 4. Then tap or click I already have a product key. 5. Enter the product key, and then click Next. 6. Read the license terms, select the check box to accept the license terms, and then click Add features. Your PC will restart automatically and Windows Media Center will be available for use.**

I have tried to follow the instructions, but I don't seem to be getting past stage 2. Does this mean that my copy of WMC is already fully activated, and the e-mail is Microsoft just spamming me, or do I need to do something.

In short, how do I know if my copy of WMC is activated?

Thanks in advance.
