Microsoft Edge is the new Windows 10 default browser which came to replace Internet Explorer. Sometimes you may run into some issues, such as sudden crashes, slow performance, or simply it won’t open. Search and homepage setting of Microsoft Edge can be hijacked. To get rid of these problems we need to reset settings in Microsoft Edge. If you were using Chrome or Mozilla, you could just reinstall the browser to fix the problem. But Edge is a built-in Windows browser application that cannot be removed or uninstalled. There are different ways to reset your browser.

Restore default settings in Microsoft Edge.

1. Open Microsoft Edge, click the More Actions menu (the three horizontal dots in the upper right corner) then click Settings;
2. Scroll down to Clear browsing data then select Choose what to clear;
3. Select all data types and click Clear;
4. Then you need to restart your computer and launch Microsoft Edge.

Reset Microsoft Edge with System File Checker.

As mentioned previously, Microsoft Edge is a core component of Windows 10, so Windows System File Checker tool (sfc.exe) may fix the problem.

1. Run System File Checker by right-clicking on Start menu, open Command Prompt and type the following command: sfc /scannow;
2. Restart your PC and try to launch Microsoft Edge.
3. Restart your PC and try to launch Microsoft Edge.

Reset Microsoft Edge through PowerShell

I recommend you to create a system restore point in case something goes wrong before doing the following step.

1. Clear all files inside the following folder:
   C:\Users\%username\AppData\Local\Packages\Microsoft.MicrosoftEdge_8wekyb3d8bbwe
2. Right click on the Start menu and select Windows PowerShell (Admin).
3. Type or copy the following code:
   "Get-AppXPackage -AllUsers -Name Microsoft.MicrosoftEdge | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register '$($_.InstallLocation)\AppXManifest.xml" -Verbose}"
4. Restart your PC and hopefully Microsoft Edge should work properly.
