Windows 10

Totally false.
I would recommend using the classic shell program from http://www.classicshell.net/
It lets you choose how your icons and menu's look and act.

If you set it for Windows 7 style it skips all that charms start page crap and gives you a normal desktop with icons and menu's like you are used to having when you turn your computer on.

Lots of our customers use it.

I also have a small entry for win8 that makes that stupid lock screen go away if you want it.
Just wait till you cant run programs on you computer, NO local data storage. No access to the source code. Get it?
