I have 3 machines running Win 10 and have personally upgraded 3 others. Only 1 caused any bother, it crashed when the owner was saying No to an upgrade (spite?). It had Win 7 and was then upgraded to Win 10 as part of the recovery process. I partitioned the hard drive using Partition Master which then trashed the MBR - unfortunately I had omitted to take a backup, mea maxima culpa! When I did a clean install of Win 10 it ran perfectly so I think there was something inherently wrong with that PC or its OS installation. Overall I am pleased with it and am recommending people to upgrade.

Hey Paul - thanks for that input. Glad to see someone out there likes it.
And,
I have heard SOME good comments about it in the past here on the forum. So - I will most likely upgrade on at least one of my 2 machines.
