Change Delay Time to Show Taskbar Thumbnails in Windows 10


Hello Eddo,

This setting affects the delay time to show both thumbnails and list.

It doesn't affect which one shows though. For that, see: Change Taskbar Thumbnail Threshold to Show List in Windows 10 Windows 10 Tutorials

Hello Joe, *Smile
