How to Disable Taskbar Preview Thumbnails in Windows 11

Just like Windows 10, Windows 11 also has taskbar preview thumbnails allowing users to take a peek into open windows. This useful feature becomes a hindrance when you are playing a game on your PC. You mistakenly hover your mouse over the taskbar and a small window will cover an area on your game screen. The only way to avoid this is to disable the taskbar preview thumbnails in Windows 11.

In Windows 11, you can’t change the view or size of taskbar thumbnails. Besides that, Windows 11 doesn’t allow you to disable the taskbar preview thumbnails from the Settings as well. Even the Group Policy fails to effectively turn off the thumbnails. So, you will have to rely on the Registry Editor hacks. Yes, you can turn off (or delay to be precise) those annoying taskbar thumbnails using a simple registry trick.

In this tutorial, we will show you the registry hack that disables the taskbar preview thumbnails completely. Besides that, we will also show you another tweak that disables preview of multiple similar windows. So, next time you hover your mouse over it, you won’t have to scroll through the similar-looking thumbnails. Instead, you will get a list with names which is more convenient.

Though we have explained the process for Windows 11, the same process also works for Windows 10 as well. So, let’s get started with the steps.

Step 1: Launch the Registry Editor

First of all, you would need to launch the Registry Editor in Windows 11. For that, press “Windows + R” to open the RUN utility, type regedit, and press Enter.

Step 3: Set the DWORD Value and Restart the Explorer

After creating the DWORD, it’s time to set its value to make it work. So, double-click the newly created DWORD to modify its value.

INFO: Before we move forward, let us make something clear to you. This DWORD doesn’t actually disable the taskbar preview thumbnails in Windows 11, instead, it delays them. So, they will take more time to appear giving you the same results.

So, in the ‘Edit DWORD window‘ select Decimal as the Base type and enter the number of seconds in the “Value data” field to delay the taskbar preview thumbnails. In this tutorial, we have used 5000 to delay the thumbnails by 5 seconds. You may use your own custom value here.

Step 4: Before and After Comparison

Now, after you have disabled the taskbar preview thumbnails, it’s time to check how it looks. Open a few windows on your Windows 11 PC and hover the mouse over the taskbar icons.

You will notice that taskbar preview thumbnails are not appearing immediately. Instead, they appear after the amount of time you have set in the previous step. Since we have set the value to 5 seconds, the thumbnails will appear after 5 seconds. Now, it won’t block your screen while you are playing your favorite game.

So, if you want to see the list of open windows (just like Windows 7) instead of taskbar preview thumbnails, you can try this trick.

Go to the following path in the Registry Editor and create a new DWORD there.
