I tried to run the upgrade from 7 to 8 just before the deadline last (?) July. It kept failing and I was never successful although I tried everything. I eventually set it up in a fresh install on a spare hard drive that I shelved eventually planning to switch over. But 7 just works so much better on my daily driver. I have 10 on several other machines and it’s fine, but I just prefer 7 on my main machine. When I replace my laptop, I will then go with 10 on it as well. But for now .. I’ll stick with 7.
Oops. Meant “7 to 10” in the post above.
I talked with two techies when I was installing some anti-virus software and on both occasions they said they personally used windows 7
