Why did you think Windows 10 would be the 'last version of Windows'? ;)
I have a new machine on Windows 10... it needs plenty of taming, including installing 'StartIsBack'.
Microsoft has abandoned/betrayed its desktop heritage... look no further than the schizophrenic Control Panel vs Personalize/Settings UI. With Build 1703, even the classic taskbar clock is no more. The good old calculator is replaced by some 'Modern' monstrosity, I had to install the old Calc.exe from Sergey Tkachenko (downloaded from Winaero.com).
It was a bad decision to merge a desktop OS and a touch/mobile OS (otherwise Apple would have done it long ago). Instead of letting Windows 10 be a mea culpa for Windows 8, they doubled down on the idiocy, and used it as a platform for the then newly appointed Microsoft CEO SatNad to data mine everyone.
