Nothing wrong with sticking with Windows 7 until time for a new computer.
echoed my own thoughts precisely.
Trouble is, I'm not in the state she is - I was on Win8 and I did
upgrade from Win8 Pro to Win8.1 Pro, then on to Win10 Pro, but now I rather wish I had downgraded to Win7 at the outset. The only thing that's stopping me is that MS Office 2016 (updated) doesn't have all its updated features enabled unless the OS is Win 10.
This is a cunning variant of the "lock-in" ploy, by Microsoft.
The path to Win10 and its upgrades has rather proven to be a mountain of pain/annoyances and a monumental time bandit, and it's not stopping.
