In Windows, when you hover your mouse cursor over an open app’s Taskbar icon, you can see a thumbnail preview of whatever it is you have open in it. This works great when you have multiple browser windows open. The thumbnail preview tells you what’s open in the active tab in that particular window. Microsoft has added a very similar feature to Edge. When you have multiple tabs open in Edge, you can hover your mouse over a tab and see a thumbnail preview of the page you have open. You might find it useful, or you might find it useless. If it’s the latter, a simple change to the registry can be made to turn it Off.
Hit Win + R, type regedit, and hit enter to open the Registry. Navigate to the following location;
Create a new DWORD entry and name it TabPeekEnabled. When you create the new entry, it’s default value is set to ‘0’ and that’s what you need it to be. If you have Edge open, close it and open it again. The tab previews will be gone.
If you want to bring the tab previews back, set the value of the registry key you just created to ‘1’ or, delete it.
This change won’t make Edge work any faster than it does. If the previews are slow to load and you find it effects your browsing experience, turning them Off will be an improvement. If they’ve never posed a problem when switching tabs, then turning them Off will not improve your browsing experience.
