Built right into Windows 10:Is there software that can add a screen without adding a monitor. where I can flick between the 2 states using alt 1 or alt 2 ... 5 etc.?
I have tried this and it appears to work. But after adding a folder icon, it doesn't recognize the icon. and if you right click on the second, all the selections appear down about 500 pixesl.Do you want multiple desktops all on one monitor? Then just use Desktops.exe from SysinternalsSuite
that does exactly what you want to do. 4 desktips, Alt1 to Alt4 to switch between
