If your computer is running Windows 10, you may have noticed that when you hover over an app’s taskbar, a thumbnail preview automatically appears on the screen. When you have a single window of an app open, you get a single thumbnail. When you happen to have multiple windows, you get a bunch of previews in a row. If such thumbnail previews definitely annoy you while using your computer, you can disable them with a simple Registry tweak. Now, take a look at how to disable Taskbar thumbnail preview in Windows 10.
Before getting started, we strongly recommend backing up your PC, as editing the registry is risky and can harm your installation.
Once you are done backing up your PC, just follow these steps:
Step 1: Launch the Run command with the keyboard shortcut Windows key + R.
Step 2: Type in regedit, and then hit OK to launch the registry.
Step 3: Once the Registry Editor window appears, you go to the following location:
Step 4: Choose the System key, and right-click on the right side, choose New, and then DWORD (32-bit) Value.
Step 5: Now, you will need to name the new DWORD ExtendedUIHoverTime and hit Enter.
Step 6: Double-click on the DWORD you just created, set its value to 30000, and hit OK.
Step 7: Close the Registry Editor and reboot your computer to commit changes.
Once done, the Taskbar previews will no longer appear when you hover over apps. If you change your mind, just repeat the same steps, but on step 6, set the value from 30000 to 0.
It’s worth noting that there’s no specific option to disable Taskbar thumbnail, the above-mentioned method is just a simple Registry tweak that allows you to delay the time to show the previews.
When you set the value to 30000, it means that you are delaying thumbnails to show on hover for 30 seconds.
