installed this latest version 14385 via windows update and you can not change the default web browser to anything but edge, also the default for video i set to VLC which you cant change
You can't right-click video files to set the file association? Right-click and Open with > Choose Another App > Always Use This app
i think 10.0.14388.0.rs1_release.160709-1635 is the rtm build, because first win 10 was 10240, second 10586 and now 14.388, microsoft say windows is a service and now build numbers say nothing by windows 10 of rtm status, because win 10 is a service os, windows 10 is a 10 years construction zone xD
yeah on wpc are many versions from 14379 to 14388 and 14388 is rtm, 14385 have too many bugs-hyper-v bug and so, and this you cant correct in millions of code sites to the next build 14386
