After about 2 hours I was able to upgrade Windows 8.1 to Windows 10. I thought every thing went OK as after the upgrade every thing worked.

HOWEVER, I would recommending not upgrading to Windows 10 at this time. After sever weeks of good performance, in the last few days I have had nothing but problems. Today as I was trying to prepare some documents for Church, the computer locked up solid and the only way I could get it back was to do a true kill by holding down the On button until it shut off. Again today, everything is extremely slow. You click and icon to open a program, and it takes forever to open.

As I said I would not upgrade at this time until Microsoft fixes Window 10.

I probably will suffer through the lock ups and poor performance until they get a fix. It took over two hours to install Windows 10, and will take time to reinstall Windows 8.1. That is several hours that I don't have to mess with a computer at this point in time.
