I was, initially, reluctant to upgrade to Win10 (from Win7) too … mainly because I don’t like the standard Win10 user-interface; all those Tiles look far too distracting and annoying to me !
But, I made the switch some time ago - and soon found that I could adjust the UI to my liking (see here) - - and I’m now very happy with the Win10 environment.
There will be some users who need the ability to continue running 16bit apps - - so, that makes it difficult to move from Win7 … Otherwise, tho, I’d encourage you to make the switch-over.
