I think Microsoft have lost the concept of an operating system which is what W10 is supposed to be. The operating system should be an efficient and easy to manage launch platform and file management system, not a glitzy marketing vehicle.

From my experience Microsoft have simply put "lipstick on a pig", there's not much difference between W8.x and 10, just as there really wasn't that much difference between Vista in it's final form and W7.
My own install of W10 was tolerable. After update on a new cloned HDD, the first use a couple of days later resulted in extremely slow startup, lockups, flaky performance and non responsive programs, my guess is because of background update stuff happening, with Lenovo's absence of an HDD led it was impossible to even guess what was happening.

After about half an hour everything settled down and performance was as expected.
One can't help but question the uncontrolled and continuous uodate strategy.

The new start menu is IMO crap, so I opted for the excellent open source Classic Shell start menu.

I may try a clean install, really nothing to lose, as I have my original W8 install safely tucked away on the original hard drive.

I guess in the final analysis they force our hand, future hardware and driver releases will mean that we have to adopt whatever flavour of operating system they serve up, try buying PC hardware that will run on XP.
