Windows 10 Taskbar Thumbnail Preview Not Working
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.
EDIT: I notice something else, if I open regedit or computer management and one of them is active, all other opened programs on the taskbar have long thumbnail preview. But if for example windows explorer is the active window on taskbar, thumbnail previews stay for a short time. In this guide, we'll walk you through the steps to edit the Registry to disable Taskbar thumbnail preview,.
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?

I believe I remember seeing that under the Performance Options.
Go to System --> Advanced System Settings --> Advanced tab -->Settings --> Visual Effects --> and uncheck Enable Peek
I had the same problem with a projected secondary display. The following procedure prevents the secondary display disappearing when hovering over the Show desktop button.
1) Right-click on the taskbar, select 'Taskbar Settings'.
2) In the Taskbar section the 5th switch down is labelled 'Use Peek to preview the desktop when you move your mouse to the Show desktop button at the end of the taskbar.'Switch this off.

3) In the Multiple Displays section, the first switch is labelled 'Show taskbar on all displays'. Switch this off.
Desktop peek now requires a click on the button, so is still available but not nearly so prone to accidental activation. Additionally, the secondary display is undisturbed even if the Desktop peek is activated/de-activated by a click.

Edit2: Further expanded to prevent taskbar showing on secondary display.
