Microsoft Edge missing in Start menu and pins

Here is the command to reinstall ONLY the EDGE browser. It will leave any other uninstalled apps alone.

Open PowerShell and run:

Get-AppXPackage -AllUsers -Name Microsoft.MicrosoftEdge | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml” -verbose}

Search for PowerShell in your start menu. Right-click it and choose "Run as Administrator".

At the PowerShell command prompt, enter: Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppxManifest.xml"}
