Microsoft Edge not working or showing up Windows 10 SOLUTION FIXED

Please use the following steps:

Open an Administrator CMD window.  If you can't find a way, use these steps:

Press CTRL+Shift+ESC to open Task Manager.
Click File > Run New Task
Make sure you have a check mark beside "Create this task with administrative privileges"
Type CMD
Type the following commands at the CMD prompt:
    dism /online /cleanup-image /restorehealth
    sfc /scannnow

This step worked for me and I had been trying for months to find a solution and it was frustrating x 1,000,000. Let me know if it works for you.

Run these commands:
1) Type in "powershell"

2) Cut and paste this EXACTLY and include the { & the }

Get-AppXPackage -AllUsers |Where-Object {$_.InstallLocation -like "*SystemApps*"} | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Check to be sure this command ran, showed a blue progress indicator and then returns to the prompt.

If you see a red error, then the command may have been typed or pasted incorrectly, or there may be an larger problem with Windows 10.  Try again.

Check to see if the issue is resolved.

If not, restart the PC.In this case try as a new administrator user account.

If the new user also fails, go up to the steps for "3. If EITHER command does not show." above. We need to repair Windows.
