Since Windows 7, there's an option to "Peek" at the desktop (overlayed by outlines of opened Windows) when you hover over a thumbnail produced by a Taskbar icon.
On a Windows 10 device, i need to disable this as it is often used in Extended Desktop mode for projecting/displaying content to the public on a second display. While in control using the primary monitor, when trying to switch windows it will often also peek the desktop on the secondary displays, which is not ideal.
Now, I've managed to disable this on a device in the past, but i now cannot find how.
Just to be clear, this is the only function of Aero Peek that i want to disable. I want to keep the taskbar thumbnails, and the option to desktop peek when hovering over the little button on the bottom right (far right of the taskbar).
Can anyone point me in the right direction?
