The word around is that Windows Media Center won't make it to Windows 10.
What started as a special Windows XP edition then a feature of Windows 7 and finally an add-on for Windows 8 is disappearing.
I personally still use a Windows 7 Media Center in the lounge, with a small form factor BRIX and HDHomerun on the network to get Freeview HD there. There are alternatives obviously and the lack of updates of late makes it now so "special" but if you want something to play and record live TV, go through your music, photos, DVDs and videos then it's hard to get past it.
The alternatives seem to be fixated on bringing a "decent look" to torrent downloads mostly - and even so with online streaming going mainstream there's a chance those media players aren't going to be part of a HT experience for long - Amazon Fire TV, Roku, XBOX, PS4, Chromecast all offer better options in content.
Our Windows 7 box will continue running as long as we have a HDhomerun in the network.
