In Windows 11 or Windows 10, when you have one or more windows open for an app, to see thumbnail previews of the open windows you can hover over or click/tap on the app’s icon on the taskbar. In this post, we will wlak you through the methods to make Taskbar show List instead of Thumbnail in Windows 11/10.
Make Taskbar show List instead of Thumbnail in Windows 11/10
Depending on your configuration for your screen resolution and DPI scaling level, the taskbar thumbnail threshold limit will vary. The following values are the default taskbar thumbnail threshold limits based on screen resolution with default DPI:
- 800×600 = 8 open windows
- 1024×768 = 10 open windows
- 1920×1080 = 16 open windows
The taskbar will only show thumbnail previews of so many open windows for an app before the threshold is reached, and will then afterwards automatically show a stacked list of the open windows.
Make Taskbar show List instead of Thumbnail in Windows via Registry Editor
If you want to make Taskbar icons show a vertical List instead of Thumbnails in Windows 11/10, you will have to tweak the Registry. Since this is a registry operation, it is recommended that you back up the registry or create a system restore point as necessary precautionary measures. Once done, you can proceed as follows:
- At the location, on the right pane, double-click the NumThumbnails entry to edit its properties.
If the key is not present, right-click on the blank space on the right pane and then select New > DWORD (32-bit) Value to create the registry key and then rename the key as NumThumbnails and hit Enter.
- Now, double-click on the new entry to edit its properties.
- Select the radio button for the Decimal value.
- In the Value data field type a number you want for the taskbar thumbnail threshold.
If you input 0 (zero) it will be the same as 1 to show in list mode after you open two instances.
To restore the default Taskbar Thumbnail Threshold, simply repeat the steps above and just delete the NumThumbnails registry key. Alternatively, you can automatically disable or delete the key – do the following:
- Press Windows key + R to invoke the Run dialog.
- In the Run dialog box, type notepad and hit Enter to open Notepad.
- Copy and paste the code below into the text editor.
- Now, click the File option from the menu and select Save As button.
- Choose a location (preferably desktop) where you want to save the file.
- Enter a name with .reg extension (eg; DeleteNumThumbnails.reg).
- Choose All Files from the Save as type drop-down list.
- Double-click the saved .reg file to merge it.
- If prompted, click on Run > Yes (UAC) > Yes > OK to approve the merge.
- You can now delete the .reg file if you like.
- Restart PC.
