Multiple desktops leave a very light footprint on your PC and consume minimal resources for its functioning. So, if you're using a low-end system with at least 4GB RAM, do not hesitate in trying it.
In fact, you can enable support for multiple desktops in older versions too, but, in Windows 10, it's dead simple-to-use. So, without any delay, let's dive into the privacy-focused world of virtual desktops.
Here's how to get started!
For using multiple desktops, one needs access to the Task View button on the taskbar. If it's not already visible, you can activate it—easily.

To do so, right-click on the task and click the Show Task View button option. Clicking this option will activate the Task View button on the task as shown below.

Clicking this button will tile all the existing opened windows (applications) in a grid in the form of thumbnails. You can easily switch to one of these windows by clicking on it.
Here, you'll also find a New desktop on the top left side. That's what we're interested in.

Clicking this button will create a new desktop. Simply, click on the desktop you want to switch to. An example is shown below.

You may note that by default the desktops are named as Desktop <Number> which looks a bit amateurish. Fortunately, you can get rid of this problem quite easily.

Simply, double-click on the desktop name and it'll convert into an editable text field. Type in the required desktop name and hit the enter key. That's it!

If you want to delete a desktop, hover on its name and you'll get the delete button on the right. Click it and it's gone forever. Make sure to save your work on that desktop before deleting it.
So, you can see, using multiple desktops on Windows 10 is so easy. All you need is to activate the task view button. Initially, you may find it, a bit weird, but once you get hang of it, there's no going back.
