Fix winget When Running PowerShell as Administrator

Symptom: winget works in your normal session, but in Run as administrator (a different admin account) it's not recognized or fails with source errors.

In the elevated PowerShell run:

Add-AppxPackage -RegisterByFamilyName -MainPackage Microsoft.Winget.Source_8wekyb3d8bbwe
winget source update

If winget is still not recognized, register App Installer too:

Add-AppxPackage -RegisterByFamilyName -MainPackage Microsoft.DesktopAppInstaller_8wekyb3d8bbwe

Then you can upgrade packages as usual:

winget upgrade --all

More info.
