I was getting along ok with win7 on an old PC and laptop.
But actually looking forward to the introduction of Windows 10,
as I'd been just about convinced by preview news, and early beta reviews that it was going to be a superior operating system.
A genuine advance on win7 and win8.

The offer of free upgrade to Windows 10 was the clincher.

So I purchased 2 identical budget price Win 8.1 PCs.
I got too good a bargain deal not to.

As soon as they were delivered, I unboxed the first of them.
Checked that there were no problems and it was operating correctly.

Then immediately carefully upgraded it to the free win 10 install.

That did not go smoothly without problems.
In fact it completely buggered a brand new PC.
My account of the trials and tribulations were posted here at mudcat.

So after many hours of futile troubleshooting, in the end I gave up and reluctantly decided to roll back to win 8.1.

That didn't work properly either, and left significant problems,
Which I had to live with from then on.

Obviously that negative experience turned the against Windows 10,
and I didn't let it anywhere near the other identical new PC.

Which is still my main day today work-horse machine.

The other still works reasonably ok,
And I'm guessing a number of years of regular system updates have helped resolve the early install and rollback faults...???

Based on my experience, not prejudice, I refuse to install Windows 10 again until it's an absolute last resort.

Then I'll buy a cheap $10 key for win 10 Pro...
