If you’re using the new Microsoft Edge browser based on the Chromium project, you can reset your settings at any time. You might need to do this if you’re experiencing issues, or when an extension or app modified your settings without your permission.
How to restore settings to default values on Microsoft Edge
To delete and restore the default settings values on the new Chromium version of Microsoft Edge, use these steps:
Open Microsoft Edge.
Click the Settings and More (three-dotted) button on the top-right corner.
Select the Settings option.
Click on Reset settings.
Click the Restore settings to their default values option.
Click the Reset settings button.
Once you complete the steps, the browser will reset the startup page, new tab page, search engine, and pinned tabs. In addition, this action will disable all your extensions and clear the browsing data. However, your favorites, history, and passwords will not be deleted. If you need to delete this data as well, you’ll need to do it from the Profiles page and deleting your current profile.
While we’re focusing this guide on Windows 10, you can also use these steps to create additional Microsoft Edge profiles for Windows 8.1, Windows 7, and macOS.
