Still working with W7 Enterprise at work, with no plan to replace it.
There are tons businesses and individuals who are in "When You Pry It From My Cold Dead Fingers" mode about Win7.
I admit, I'm largely (though not entirely) in that camp too.
Windows 7 Professional user here...works great on a Dell.
Microsoft 7 was a good program. After some possible hacking problems, Microsoft put in W8 and totally screwed it up, leaving out links, possible security software, etc.
Damned. I miss WordPerfect 5 and 7. Never had any problems with them.
My husband got a Win10 laptop for our business when they first came out to ease him into using the new operating system. He still has trouble every time he takes the thing out. All this time and he has not adjusted yet. If it’s not the software, the hardware is incompatible where he goes to speak.
He is not the most tech savvy person in the world and as soon as something goes wrong he panics.. His desktop is Win7 and he has trouble enough with that one. Why can’t they make it easier on non-technical people?
Win10 has been just fine for me so far. It only took me a couple days to get with the program. I got it with a new machine. I would never update an old one with that system.
