If you have a Windows 10 device, there’s a good chance you are familiar with the Windows taskbar preview feature. If you aren’t and this is the first time you’ve heard of it, it’s the feature that allows you to hover your mouse over any task in the taskbar to view a small preview of open, yet minimized content.

In a recent guide we showed you how to increase or decrease the time it takes for a preview to appear when hovering your mouse over taskbar tasks. In this guide, you’ll learn how to increase or decrease the size of the taskbar preview window on Windows 10. Although making this change is quite easy, it will require you to use the Windows 10 registry editor. Because of this, it’s important to make sure you have a system restore point set before beginning.

If you haven’t created a restore point before, do the following. Open the start menu, type Restore, then select Create a Restore Point when it appears on the list. In the new window that appears on the screen, click Create in the bottom right corner of the screen, then follow the on-screen instructions. Once a restore point has been created, you can safely start the steps shown below.

After making the change, Restart your computer or sign out of your account and change will take effect. If at any stage you wish to revert back to the default setting, simply return to the same registry location and delete the MinThumbSizePx you created. After another Restart, the preview window will be back to its standard size.
