I built my HTPC maybe 5 years ago. After testing what was available at the time I built it around WMC and some plugins which worked well enough for me. But since then much has changed. Streaming, integrated keyboards rather than remote controls, catch up TV for a start. So now there is less emphasis (OK none at all really) on an integrated HTPC environment because using the PC as a PC from an armchair is easy. Anyway moved to Win 10, VLC for movies, Spotify for music, NextPVR for recording fta, a browser for catch up TV and the occasional subscription for must see pay tv, all bases covered. Not looked back, not really missing WMC although it was a good thing at the time. And despite having a NAS for media storage, streaming services means its barely used for that purpose any more. Life goes on.
