I know I'm in a minority here, but having used every windows since 3.1, IMO windows 7 was the absolute pinnacle of windows design, and from a ux perspective I think the best desktop os period (could still be improved, there's definitely individual features that are better in other OSes). I really wish they had stuck with the UX/design and mostly just improved performance/added useful stuff rather than throw it all out and start over.

You're not as big of a minority as you think. Windows 7 is still the most used desktop OS by quite some margin. MacOS hit its pinnacle at about the same time (Snow Leopard, Summer 2009).

I've seen problems with websites as IE versions are upgraded, but that happens with or without Windows 10.

I haven't seen any issues with apps though, so I have to dispute this claim. We just moved 5,000 employees from Windows 7 to 10, and it went far smoother than anyone really expected - everything just works. It's a wide range of apps too, everything from in-house WPF apps to CAD and engineering software.

Janky enterprise crap optimized for IE <whatever> is one big example. The other is old Office stuff like Access databases or workflows dependent on conversion of old file formats. (Last year Office 365 ProPlus purged legacy DBase import for a few months)

IE11 support will go away at some point. Many of those apps are now being updated to work on Chrome -- I know of a few large shops that aren't testing IE or Edge anymore for internal apps!

I do agree that they did a heroic effort on making the update process incredibly reliable. Most non-prehistoric applications transition seamlessly.

Note that I personally equate Windows 10 and the subscription "Office 365 ProPlus". The layers of complexity are astounding. I present to you what I call the "Office 365 ProPlus Build Decoder Ring" - https://support.office.com/en-us/article/Version-and-build-n...

Windows 10 itself has about 8-10 releases that an enterprise needs to think about. Transition from release to release has gotchas and additional Windows-Office gotchas. (For example, the way Office authenticates changes in certain builds) (See: https://www.microsoft.com/en-us/itpro/windows-10/release-inf...)

Haha. I'm living this right now, but we're getting there. We'll have a few thousand PCs on Win 10 soon and will finally deprecate IE8 for Chrome :p. I'm dead set against using iPads for anything serious although I keep losing that battle.

Agreed. They are undermining the areas where they had most strength. It seems rich desktop apps are being pushed aside in favor of the app store model. For new stuff we now usually choose web over WPF.
