Clicking on the Desktops symbol (two, overlapping gray squares) will open a display of all your open programs and desktops you've created. If you haven't done anything with a second desktop yet, your display will look something like the above.
You can also simply scroll over the Desktops symbol to see how many desktops currently exist.
Create a new Virtual Desktop by clicking on "New desktop." This will open a new, empty desktop, on which you can open any apps or programs you'd like to run. All the open programs on your original desktop will stay open, and you can navigate back to them by hovering over the Desktops icon and then selecting 'Desktop 1'.
Another way to create a new desktop is to use the keyboard shortcut Win + Ctrl + D.
You can also rename your desktops for an extra layer of organization by clicking on the text that reads 'Desktop 1' and typing in a new name. You can see above that I've renamed Desktop 1 'Howchoo.'
And just like that, you're more organized than ever before thanks to Virtual Desktops in Windows 11!
