kyrios windows has virtual desktop ?
Yeah, Windows 10 and probably Windows 11 do. I'm not sure about earlier versions. I no longer remember the steps I took, but I created 5 virtual workspaces on Windows 10, just in case I needed them. I never used more than two, for the Nook app and the Ring doorbell app, which were only available for Windows and Android, not Linux.
Since Ring discontinued their Windows support, I could get rid of the multiple workspaces now and just use the main Windows workspace to read my Nook books. It's probably more trouble than it's worth, though.
I'm fairly sure the same feature is build into Windows 11, but they're heavily promoting Azure now, so maybe not.
EDIT: Allthough I don't remember how to set them up in Windows, I do remember that you can cycle through the desktops with Ctrl+Windows and the Left and Right arrow keys. The workspaces don't show up anywhere, so the only way to know for sure which one you're on is to cycle all the way to the left or right and count them as you go. Nowhere near as convenient on Linux.
