If you find Microsoft Edge's tab preview not being a useful feature, in this guide we'll show you how to disable it with a small tweak in the registry.

While Microsoft Edge still has a few miles to go to catch up with the competition, Microsoft has done great work on bringing new features, improvements, and making the web browser more power efficient.
Among all the features in the default web browser for Windows 10, you'll also find tab preview. This feature allows the browser to show a small thumbnail (very similar to the thumbnail for apps in the taskbar) that gives you a peek as you hover the mouse over open tabs without the need to move away from your current page.
This little feature can be useful for some, but it can also be distracting for many users, as it can get in the way of elements of the web browser. Fortunately, there is an easy way to disable preview for tabs on Microsoft Edge by modifying the registry.
