Since alot coworkers asked me:
(windows 10)
Press win+tab, klick the "add desktop" thing in the bottom right corner, add as much Desktops as u like. Now change them very smooth with strg+win and <- or ->.

Move windows with the win+tab thing to other desks

I tried multi Desktop for years on linux and with 3rd party tools on windows. It never worked well, was unsexy and bugged or programms could not handle it.

The win10 stuff is the firsr really cool working multi Desktop thing. I still even use it with 2 or 3 monitor setups. I hate to minimize and maximize programms. Usually i got a Desktop to code one for doc, one for Test runs and one for administrative stuff (Outlook, reddit, 9gag).

Try it, you will hate it when you then need to work without it =}
