The only improvement I've seen with W10 is saving screen shots.
I can't stand the W10 tiles and the start menu tiles. I delete things and they reappear and new tiles appear for sites I have no interest using.
I have used the program to restore the old start menu but W10 keeps reverting to the new tile system.
One of the worst new W10 functions is the Search.
With XP when I did search it searched for what I was looking for on my computer. Now it searches the internet.
That's not what I'm looking for with the search function.
Do your search in Windows Explorer (the little file folder on the bottom of your screen). It’s not rocket science and it works just like the stupid dog in WinXP.
