Look for #WindowsMediaCenter and #WMC on twitter.
Pretty much almost started #WindowsMediaCenter (there was only 5 posts on twitter using that hashtag when I started using it), and #WMC is used for something else, There is an event of some type and they use that hashtag
Look at my sig and look over my tweets, you can clearly see I have been tweeting for Windows Media Center.
So you use WMC and it does what you need, how would upgrading the underlying OS to WIN10 be of benefit to you? I mean why should you upgrade if what you have works for you? Windows 10 as an OS would actually not benefit you much for the purpose you use WMC for..
Updated hardware support, faster load times, better networking subsystem, new apps that could be scripted to use in WMC as a full screen remote controlled app. There is a bunch of advantages to it.
On the other side of it, I need Windows 10 on my office/gaming machine to support DirectX 12 (7 and 8.1 wont get it) and my hardware is all up to spec to support it (i7 5820 ad GTX970). I use a shared Ceton tuner, so on my Office machine, I can watch live tv from the cablecard sitting in the main HTPC, a feature I use a lot.
Right now, unless Windows Media Center comes, once Windows 10 is final/RTM, I will have no choice but, to dual boot, Windows 7 for work and TV, Windows 10 ONLY for gaming.
Sure I would like to use Windows 10 for everything when it goes to RTM (like what they have done with it so far) but, with out Windows Media Center that is a major part of my media based life in my home, I wont be able to go to it.
I personally know a LOT of people who use WMC in a office type of thing to watch tv, news updates, etc, after discussing with a lot of these people, 90% of them have NO plans on going to Windows 10.
Good job Microsoft, a small app that a lot of people still use for TV that is one of the best programs you ever created, it will work on Windows 10 (I can confirm that) but, instead you just want to create fragmentation in Windows.
Nice job....
