Windows 10: no preview on taskbar anymore windows 11

whenever I hover over an open icon on my taskbar it automatically opens the program instead of letting me see a preview of the program I don't have the ability to click on it it just automatically switches is there a way to turn this off or restore it to the default way

:)

 

Windows 10 taskbar app icon not showing preview (Taskbar Hover preview)

 

Windows 11 taskbar preview not working properly

The OP said it was Windows 11, not Windows 10.

It happens to me, as well, with Windows 11.

OS Build is: 22621.1105

Preview on taskbar works randomly (apparently).

Any solution?

Thanks,

Alberto

 

Failed to disable Peek Preview in Windows 11

Hi, everyone!

To implement some custom fetatures I need to disable peek preview for the window. So I call DwmSetWindowAttribute with DWMWA_DISALLOW_PEEK set to True to disallow peek preview. It works well in Win7 and Win10 but in my newest Win11 machine, it sill shows peek preview when the mouse hovers over the window's thumbnail in the taskbar.

And I use a demo from VS2019 to reproduce this bug and still it works well in Window 7 and Window 10, but not in Windows 11.

I also read the SDK document and I don't find changes relevant to this behavior. Do I misuse this interface? If you know the right way to disable it, let me know plz~~

Steps to reproduce the bug

1. Open Visual Studio 2019 and New C++ Desktop Project.
   
2. With a built-in demo, disable peek preview with DwmSetWindowAttribute
   

1. Add link dependency dwmapi.lib
   
2. Compile and Run
   
3. Window shows but it still shows peek preview.
   

Expected behavior

No peek preview in Windows 11 22000.829
