How-to run the edge browser as built-in (local) administrator on Windows Server 2016 or Windows 10

When you’re logged in with the built-in Administrator on a Windows Server 2016 or Windows 10 box, you can’t start the Edge browser.

Default security will prevent you from using the Edge browser and suggests you to login with a different user.

To workaround this, you can follow these instructions:

1.  (windows+r) run gpedit.msc
2. go to: Computer configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> User Account Control: Admin Approval Mode for the Built-in Administrator account -> Enabled
3. Reboot the Windows Server 2016 box (windows+r -> shutdown /r /t 0)
4. enjoy using Edge with the local administrator account
