1709 is an upgrade, not an update, and it will change you configuration settings.
Last upgrade on my main workstation (1706) changed the configured order of MIDI devices in Splat and I had to reroute everything to the correct ports and instruments. Grrr..
I also had a similar problem where Windows Media player no longer recognized all .mp3's depending on bit rates.
To correct that, all I had to do was to go into "Default App" settings, click on "Groove Music" which it most likely defaulted back to during the upgrade and choose Win Media Player from the drop down menu to choose it as the default player for music. Also scroll down and do this for default video player and Windows Media Player plays every format, even Quick Time .mov, .mp4, and DVD's.
Hope this fixes your problems, as it fixed mine.
