Although Windows 10 is a horrible product it is not something that I can get as worked up about as some others do. Best just to avoid it.
I tried it for a month on one of my machines (a Dell desktop previously running Windows 7 that has FTP and Hauppauge TV servers, plus normal office s/w) and found that it got in the way of my work. I can see the use of a new UI when it makes work easier but one that requires learning and then makes matter worse has no place in my life. I used Macrium to restore my Win7 environment. I make no apologies; I am a WIMP man!
Win7 is set to be supported until 2020 and all of my machines will be replaced by then so there is no need to move them to Win10. I have an old PC linked to my sound system for music and that runs Lubuntu and I have a Sandbox running other Linux flavours to see how they are getting on (Ubuntu, Ubuntu Mate. Linux Mint). They are not quite ready for the general public yet but they are getting there (any OS that in normal work requires you to open a terminal and type sudo apt-get update then sudo apt-get install ......... is a fail).
I have put Windows Update on "Notify but don't download" ie no automatic updates, banned a bunch of specific updates* that push Win10 and increase telemetry etc and have put a Microsoft block list in my Peerblocker. That is me sorted until 2020 unless I have to buy new h/w in the meantime and I shall deal with that when it happens. Fives years is a very long time in computing and who knows, Win10 may go the way of Vista by then. Microsoft is not invulnerable; look at Nokia.
