How to fix Microsoft Windows Edge Not Working in 2021?

How to fix Microsoft Windows Edge Not Working in 2021? Microsoft Edge is an official Windows 10 app and is therefore particularly protected against compromise and manipulation. Nevertheless, the browser can have hiccups or simply refuse to work. We’ll tell you here how you can repair.

Summary: Usually Microsoft’s browser should run smoothly. As a Windows app, it is in a secure environment and the modifications that users can make to Edge are severely limited. However, if the pre-installed browser should ever give up, you can quickly get it back in shape with a few simple steps. We introduce three methods of how to fix Edge.

Repair Microsoft Edge

Smaller issues with Edge can often be resolved through repair. Fortunately, this is very easy to do under Windows 10. To start the repair process, you must first go to the list of all installed apps. To do this, click on the Windows logo in the taskbar and then on the gear wheel to get to the settings.

There you then select “Microsoft Edge” in the list of apps and click on “Extended functions”


Then the tab opens. Scroll down there until you see the options “Repair” and “Reset” under “Reset”. Now select “Repair”. After a short time, a small tick will appear next to the button, indicating that Edge has been repaired. Then open the browser to see if it works properly again

Reset Microsoft Edge

If the repair did not lead to the desired success, you still have the option to reset Edge. Some data such as the browser history will be lost. Favorites, tabs, settings and cookies are retained. The option is located directly under “Repair”.

Again a small tick indicates the end of the process. Then test whether Edge is working again.

Reinstall Microsoft Edge

If both measures failed, you can try to reinstall Edge as a last resort. However, since Microsoft’s browser is a system component of Windows 10, reinstallation is not that easy to do. Windows 10’s PowerShell provides the solution. To open the special command prompt, enter the term “powershell” in the search. It is important that you open the program as an administrator.

Then confirm the dialog box with “Yes” and a window with an input request will open. If Edge only does not work under your Windows account, copy the following code 0xc000021a, right-click it into the Powershell and confirm with Enter:

Command to reinstall Edge for the current user account
Get-AppXPackage -Name Microsoft.MicrosoftEdge | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$ ($ _. InstallLocation) \ AppXManifest.xml” -Verbose}

If Edge no longer works on all accounts, reinstall the browser system-wide with the following command:

Command to reinstall Edge system-wide
Get-AppXPackage -AllUsers -Name Microsoft.MicrosoftEdge | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$ ($ _. InstallLocation) \ AppXManifest.xml” -Verbose}

  • Summary
  • If you have minor problems, you should first try to get Edge fit again using the Windows 10 or 0xc000021a repair function.
  • If Edge continues to refuse service, it can help to reset the browser.
  • If neither option promises any improvement, the browser can be reinstalled via Windows Powershell.
