Pine Man we are nearly the same as you, 1 Mac, 1 Windows desktop ( my wife's) 1 Laptop which I upgraded! to Windows 10 to check it out.
Very disappointed with 10, I am seriously thinking about getting a Mac Laptop and ditching Windows altogether, the Windows laptop is on the way out and I will have to decide how to replace it anyway.
10 completely screwed up my PC, I had to take it to a tech shop to get it back to 7.
I'm going to avoid 10 like the plague for at loeast 6 months.
The tech guys told me to wait until the bugs are sorted on 10.
It's always going to be difficult for Microsoft Windows operating systems to work for everyone. The main issue is that Windows don't make PCs. Lots of companies make them to different specifications with all sorts of different hardware, which Windows has to try and cater for. Apple make their own computers and then make the operating system to suit so they have a distinct advantage.
