If you ever need to download the stable version of the chromium based Edge via powershell, you can use the following one liner:
# Stable # Invoke-WebRequest -Uri "https://c2rsetup.officeapps.live.com/c2r/downloadEdge.aspx?ProductreleaseID=Edge&platform=Default&version=Edge&source=EdgeStablePage&Channel=Stable&language=en" -OutFile "EdgeSetup.exe" # Dev Invoke-WebRequest -Uri "https://c2rsetup.officeapps.live.com/c2r/downloadEdge.aspx?ProductreleaseID=Edge&platform=Default&version=Edge&source=EdgeStablePage&Channel=Dev&language=en" -OutFile "EdgeSetup.exe"
