Are you serious ?
I have a Dual Processor, Win 10 machine that is pretty fast ... Bot oh Boy .... I downloaded DR 12.5 Free ..... all 401mb of it ... it insisted on loaded up extra sql programs ....
When I started it ... I went and had coffee waiting for it to load up AFTER going through their registration ...
WOW - do people really use such as this ???
OP asked for "reasonable PC program for Windows 10 to somehow edit, add music, and save to be able to send the videos to family and friends without using YouTube and or Facebook" ..... not a Hollywood Film Studio !!
I appreciate that for free its a mighty set of tools ... but really ...
