In the early days I made it quite clear that I did not like Win 10 and that I'd stick with Win 8.1 because it is fast, stable and reliable. In fact, I'm still using 8.1 on my main rig and am happy with the choice to remain with it. However, I have Win 10 0n my HP 2-in1 and like it much better now that I've tweaked it to suit my likes and needs. In some cases I used 3rd-party apps to achieve the desired result, but often times I could adjust things in 'Settings' to apply my personal preferences.
In a nutshell, I like Win 10 better than when it was first released. With my own tweaks and some Windows updates, 10 is a more usable OS and subsequently is getting better all the time. Is it my favourite OS of all time? No, and it may never be, but I have learnt to co-exist with it and find a happy medium. It isn't all the way there yet, but I have high hopes that 10 will be made better, either through Windows Update and/or 3rd-party programmes. Heck, I may even install it on my main rigs some time further down the track.
