I've been using WMC since all the way back in 2004/5 when I first discovered it in Windows XP MCE. I used it for DVRing my satellite stream. I converted my whole family over to it (including the hardware, setup and config). Up until about two years ago, when most of them switched to overpriced cable co. provided DVRs and streaming things, as hardware started to die.
I personally still use a WMC HTPC on W7x64 for playing networked content. I have long since gotten rid of the tuner/capture cards.
With WMC gone, I might switch to Kodi. But I will still run w7 on that PC - the hardware is too old for 8.1 or 10.
MS is a master at hitting the market too early and then just screwing the pooch royally and exiting the market right when they should be doubling down with loads of experience in hand.
Media Center great example.
Zune - great software. hardware wasn't bad evidently. The song credits each month was a twist. Dump all of it and just start marching backwards yearly.
Live Mesh/Skydrive - build build build...haha, fooled you! Back we go!
Windows Home Server - gee, a central hub like device roping it altogether nowadays, tightly integrated with the cloud, multi user aware, plugin capability, usage of some local storage (and dead simple at that) wouldn't be popular AT ALL nowadays, would it?
Windows Mobile/WP - hmm, so the interface is pretty bad on WM6, eh? But people do appreciate the open/flexibility of it? Well, let's get some pretty innovative interface work out, but dump the features and openness in WP7. Okay, let's keep ignoring features in WP8, but start taking away some of the forward looking integration of WP7. Features? Well, we have some half hearted Android copies, but no, still a hot mess in 8.1 and btw the interface is going backwards. Welcome to WM10! Interface should be back to the desktop on a tiny screen feel, but no features because we are reinventing everything again. BTW, we aren't inventing gapless playback yet. Hahahahah.
While I stare at the wall drooling and wondering what I'm going to do with an ancient HTPC and a WHS v1 packed with DVD folder rips, our Roku, Fire Stick, and DVD player get used. Bah. :\
