If it ain't fixed, don't broke it
^ Your post line (or what ever they call it) sums it up. ^
But not for Microsoft. Theirs is something like "If it ain't broke, break it anyway, and then charge people to sorta' fix it again." Windows 8 was a REALLY broken toy. So now we are supposed to be happy that they fixed some of what they broke. I am a system builder, been building computer systems for the past 11 years. For my personal use, I'm sticking with Win 7 (also still have a Windows XP system, to run some programs that don't work on Windows 7). Sure, they wanted to get rid of XP back when 7 came out, but I've never seen a company put out so much effort to kill one of their own products as Microsoft is doing now, with Win 7.
Office 365 is another matter, At least you do still have the option to get a Desktop version of Office, so that you don't have to pay a yearly subscription fee. (Also, just in case there are those who do not know, Office 2019 will not install on Windows 7. It requires Windows 10. But there ARE other options, especially if you do not need to exchange files with someone who is using the Microsoft Office products, but mainly only if the file is using macros. Check out OpenOffice, or LibreOffice. Both still have the old familiar Menu Bar like all programs used to have. I use LibreOffice myself.)
But even though professionally I strongly dislike 10, for the user who is just doing the normal home owner sort of things, the adjustment shouldn't be too difficult. My task is different, because all of my customers are non-internet users (Amish & very conservative Mennonite), and they also require restrictions to be put in place to prevent gaming, videos, music, and of course, all internet access. Every time I have to do a program installation that requires major updates, one that cannot be done off-line, I have to recheck the required security settings to be sure that Windows updates haven't wiped all of my custom settings. (That happened when I updated my Windows installation image last November, to meet installation requirements for the accounting program QuickBooks.)
