:iagree: Classic Shell is wonderful!
For me, it completely transforms Windows 8/8.1 and I couldn't live without it. I use its Windows 7 style start menu, but it is nice to have the option of the older type. The Windows 8 start menu can make some sense on a tablet, but the Windows 10 one is neither one thing or another. As far as I can see its only purpose is to push content into the faces of users, whether they want it or not.
Feedback for Microsoft? Simple - stop now before it is too late.
Just about everything you have done with Windows 10 is wrong, wrong, wrong. :a
Even the basic aesthetics are hideous and look like they've come from an early smartphone.
Go back to Windows 8.1 and tweak the UI. Put all of the settings back where they should be. Vista & 7 were bad enough, but having to switch between two fundamentally different interfaces - desktop and tablet - looking for a simple on/off switch is unacceptable. And give us a choice of start menu. That could be released as Windows 8.5, with a free upgrade for all - but one with a serial number & proper statement of entitlement & usage rights.
Now that the hardware has significantly improved (and crucially is now based on Intel x86/x64 & compatibles) Windows undoubtedly has a place on tablets - but never at the expense of desktops. So Windows 9 should have an optional tablet mode, with a settings screen which duplicates the commonest settings pages and (if the user choses to use it) a development of the Windows 8 start screen.
This shouldn't be too difficult to do. A GUI should sit on top of the operating system, not have its tentacles embedded deep into the core code. If Microsoft has cut corners, done a bodge job and violated this long-established principle, then its dream of Windows on phones, tablets, televisions & fridges will never happen. A good, usable, universal UI for all devices is impossible.
As for the spyware... obviously that is unacceptable under any circumstances! If you really thought that was a good idea, then there truly is no hope and we should all jump ship to Linux immediately.
(Apple & OSX as an alternative? Don't make me laugh. Who do you think Microsoft was trying to copy?)
