Opening a PDF in a Windows virtual desktop should open an instance of Acrobat in the current virtual desktop
With the introduction of virtual desktops in Windows 10, some users such as myself have multiple projects going on simultaneously. The virtual desktop feature greatly aids compartmentalization in this aspect.
Let us say I am working in a virtual desktop called vd3 for instance, and I do not currently have an instance of Acrobat running on vd3. Now I open a PDF file and there is already an instance of Acrobat running on a different virtual desktop, say vd1. Now, instead of opening a new instance of Acrobat in vd3, Windows forces a switch to vd1 and opens my PDF in a new tab in the instance of Acrobat on vd1 instead of in a new instance on vd3. This impacts productivity.
If there is already an instance of Acrobat open in the current virtual desktop, then this works as expected: a new tab is opened in the instance of Acrobat in the current virtual desktop. However, one must first manually remove a tab from an existing instance and then move that new instance to a new virtual desktop and this can become a nuisance.
It would be a good quality of life upgrade if a new instance of Acrobat was automatically started in the current virtual desktop if there is not an instance of Acrobat already running.

Navigate to any PDF on your computer and right-click the document icon. Hover over the pop-up menu and click “Choose default program.” Click your version of Adobe Acrobat from the Recommended Programs list, then click the “OK” button to set your choice.
