Hi Russ:
I switched to Windows 10 because the free upgrade is until the end of July, then you have to pay for the upgrade. I was using 8.1 and I don't see much difference in 10. It has some new features and some quirks, but I didn't have many problems. I converted 2 pc's with no problems, but 1 is giving me fits trying to get the upgrade to work and I may have to take it back to factory settings and start all over with it. It was bought with factory supplied software and that may be part of the problem.
