In general, there is a program displayed on another monitor, but I can still roll it up through the alt + tab, if this program is a game, it will stop until I return to it. By the way, this program can also block work with windows in the main monitor.
With win7, you can make this running program not interfere with the use of a computer, and the user does not interfere with the operation of this program? maybe win10 can help me? they also made virtual desktops
