Good news Scruffy! I'm glad you got past your upgrade woes.
I find Windows 10 Pro to be stable, but my beef about it is when it updates, it will reboot your computer, no questions asked.
This occurs overnight and if I leave applications open before an update, too bad for me. I have tried several ways to override the automatic reboot to no avail.
Since I maintain software that I wrote 20 years ago and is still in use, the development environment is no longer supported by Windows 10. I had to purchase VMWare and create a virtual machine running Windows 7 so that I can continue to support the software.
