I upgraded to Windows 10 several months ago and had no problems except one relatively minor glitch: I could no longer attach pictures to an email in Windows Live Mail. Apparently, it was a known, common problem and there were several work-arounds, one of which I use. It is cumbersome, and I would think by now there would be an upgrade for Windows Live Mail that solves this problem. Is there, or will there be eventually? I am on Windows Live Mail Version 2012 (Build 16.4.3528.0331). I installed it several years ago under Windows 8.1 and without doing anything it continued to work well in Windows 10.
