By default in Windows 10, hovering the mouse cursor over the button (icon) of an open window such as an app displays a reduced version (desktop preview) of that window. If you don’t need the desktop preview, you can hide it. If you can’t hide it in the settings, you can also deal with it by editing the registry. This page introduces how to hide/show the desktop preview displayed on the taskbar.
Taskbar desktop preview display settings
The desktop preview display settings are controlled by the switch button in “…Preview the desktop” in the taskbar settings.
2. Use the preview to preview the desktop when the mouse cursor is placed on the “Show desktop” button at the end of the taskbar, set the display with the switch button .
- Hide “off” preview
- Show “on” preview
Desktop preview in taskbar cannot be hidden by setting
Hide preview in registry edit
If you are not confident about the operation, please make a backup before editing and then operate the registry.
- Right-click the “Windows” mark to display a menu, and click “Run” to open “Run”.
- Type regedit in the text box and click OK.
- Click Yes when the User Account Control warning appears.
- It will not be displayed if the User Account Control setting is set to “Never notify”. (Reference: Disable UAC )
1. Open the registry key Click the ” >
” icon of the key name in the registry editor to expand it.
Expand in order with Explorer .
2. Add value to registry key. Add a value to the ” Advanced
” registry key in Explorer . Right-click the “Advanced” registry key and point the mouse cursor to “New” in the displayed menu. Click “DWORD (32-bit) Value (D)”.
At the bottom, a newly created value is created with the name “New Value #1”.
Rename the value to ” ExtendedUIHoverTime “.
* You can change the name from the menu by right-clicking “New value #1”.
Check if the name of the created value is correct. 3. Correction of value data
Right-click “ExtendedUIHoverTime” and click “Modify” in the displayed menu.
The edit screen for the value of ” ExtendedUIHoverTime ” is displayed. Change “Value data” to ” 9000 ” and click “OK”.
This value is entered in “hexadecimal” for the amount of time to hide the preview. You can also select “Decimal” and enter microseconds directly. Since I entered “9000” in hexadecimal, it means that it will be hidden for about 37 seconds after hovering the mouse over the button on the taskbar. So if you keep hovering your mouse over it, the preview will appear after 37 seconds.
4. Completing Registry Editing
This completes editing the registry to hide Desktop Preview. Since this is a registry operation, you will have to reboot for the edits to take effect.
Restart Windows 10 and the taskbar preview will disappear.
