How to adjust thumbnails Taskbar Win 10 application

Thumbnails on the Windows 10 Taskbar when hovering over the application icon will look like the following.

Step 1:

Press the Window + R key combination to open the Run window and enter the keyword regedit and click OK to access.

Step 2:

In the Registry Editor interface, access the HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerAdvanced directory path .

Step 3:

Right-click Advanced and select New Dword (32 bit) Value .

Then enter the new name for the value as ExtendedUIHoverTime .

Step 4:

Right-click on the newly created value and choose Modify , or you can double-click the newly created value.

A dialog box for changing the value data appears, users can enter 30000 in Value and then press OK to save. Finally, restart your computer for the changes to take effect.

In fact, Windows 10 has no way to turn off Preview Thumbnails thumbnails on the Taskbar, but only adjust the display time. The value of 30000 means that after 30 seconds the new thumbnail is displayed when you hover the application icon on the Taskbar. The higher the value of this value, the longer the time.

In case you want to return to the default setting, displaying the application thumbnail as soon as you hover over the icon just changes the value of the ExtendedUIHoverTime to 0 or deletes it all.
