Windows 7 Pro 64 bit forever person here.
IMHO, MSFT has been amazed that Win 10 has not already overtaken Win 7.
Win 7 is very durable and is still used a bunch in business. I have a good friend who does IT chores for many businesses here in town. Almost all of them are running Win 7 and have no plans to upgrade. A few of his customers tried Win 10 but all have gone back to Win 7.
Some of his customers have business-critical custom code written under Win 7 that will not run under Win 10 without some very expensive rewrites. In some cases the quoted price of the rewrite is more than the original price. And the rewrite must be tested, documentation will need to be changed, etc. Not a cheap investment.
MSFT has put these folks between a rock and a hard place.
Yep. I have been working with Win10 at work (I'm a Sysadmin and support a lot of Win10 users), and I have not yet found any useful UI functions that Win10 has, that Win7 doesn't have, except of course for the things that Microsoft has declared shall only be released for Win10, like the latest version of MS-Office.
OTOH, I have found many useful UI functions that Win7 has, that Win10 does not have. And after 2-1/2 years, Microsoft has more than used up my patience, waiting for Win10 to catch up to where Win7 was half a decade ago.
That said, the underlying OS of Win10 is improved over Win7. It's snappy and very stable. But the Win10 UI just plain sucks IMO and it ruins the experience for me. Classic Shell is a great improvement; it makes Win10 usable.
I have to agree. W10 is fine for home users but in an enterprise setting it is problematic. My “regular” job oversees approx 1000 users. 90% of which are on W7 64 bit. 80% of the issues come from the 10% of W10 machines.
Same for my side gig. Six users. 3 are W10. All my IT support calls come from the W10 users.
