Hehe, the joys of Windows. Microsoft changed things in Windows 10, and put the RAW codecs in Windows itself, not separate installable codec packs anymore. For some weird reason they don't seem to update for newer cameras, people who do clean Windows 10 installs appear to get updated RAW support, but the normal Windows update routines don't?

 

Again, glad I have Macs.

 

But, you can try http://www.fastpictureviewer.com/codecs/ if updating Windows 10 does not help.
