VirtualDesktopIndicator is a free app that allows you to see which virtual desktop is in use on your Windows 10 machine.

It will keep you informed of the current desktop right from the systray as well as the number of virtual desktops present and eliminating the need to bring up Task View to figure out where you are. It is designed to be a simple to deploy info-only utility. It will be useful for those that use a number of different desktops throughout the day and need to keep track of exactly which one you are currently in.

VirtualDesktopIndicator is simplicity at its best, no configuration just the info you want for a specific task - tracking your virtual desktops.
