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?

  • @Ramhound, i dont want to disable Taskbar Thumbnail Preview though. I want to keep the thumbnails, but i want to disable the fact that when you hover on the thumbnails, you can "peek" onto the desktop – Salem874 Jan 26 '17 at 20:36
  • "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." - This is the question you asked. The current answer you received does exactly that. Might not be the way you want it to be disabled, but how you want it, isn't an option. – Ramhound Jan 26 '17 at 22:05

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

Disable Peek

  • Thanks. This disabled peek entirely though? Is it not possible to only disable it when hovering over the taskbar thumbnail preview? I'm pretty sure i got this working previously? – Salem874 Jan 26 '17 at 20:40
  • @Salem874 - I doubt it. – Ramhound Jan 26 '17 at 22:05
  • I did not work for me. – Jeffz Dec 30 '17 at 21:37

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.

Edit: Updated for Win 10 from https://www.askvg.com/how-to-disable-aeropeek-in-windows-7/

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

  • Why is step 3 required? – Annan Mar 12 at 18:02
  • Just for completeness. I don't want the taskbar jumping up on the secondary display. – Terry1951 Mar 13 at 20:27
