I have 5 or 6 virtual desktops in Windows 10, both on my home PC and my work desktop. At work, I'm able to have e.g. a separate instance of Sublime Text open on every virtual desktop, and on any given desktop when I hover over the taskbar icon, it will only show me the windows that are open on the current virtual desktop.
However, on my home laptop (which I keep updated, unlike the work PC which is strictly managed by IT), I see EVERY window from EVERY desktop when I hover the taskbar icon, no matter which desktop I'm on.
I'm fairly sure this is a Windows setting and not an app-specific setting because it happens for both Chrome and Sublime Text.
How can I change this behavior back to the way it used to be? Is there a particular Windows update that I need to roll back?
