Windows 10 taskbar not showing stacked applications thumbnail

[link6155]

Hi,

 

Whenever I have multiple instance of the same app open, the thumnail doesn't show, instead it shows a list. This started happening after I upgraded my GPU (RX 470). How do I revert it back to the default behavior where it shows all thumbnails?

I think you right click on taskbar then go to properties, in there should be an option similar to the one I've attached in the image below

I'm on 7 so not 100% sure what the steps are for later windows, sorry. You're looking for a 'peek' setting. And check to see what your taskbar buttons is set to, just in case they're set to always combine.

Are you comfortable editing the registry?

 

Navigate to the following key

 

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced

 

What is the value set to for the ExtendedUIHoverTime key?

Does it show the thumbnail when you have only one instance open?
