When will Windows 8 release virtual desktops?

The absence of a Virtual Desktop that I usually use in Windows 10 is also one of my inconveniences in using Windows 8.1. Actually the desktop swipe system which can easily make us switch from desktop to application just by swiping our finger from left to right is very practical. Unfortunately this only applies if I'm using a desktop plus an app from the store. If I use non-store software, it will "count" as a desktop, so it's less easy for me to switch between apps while using this device.
