Download Files Using Command in Windows Server Core 2016

I have a Windows Server 2016 in Core mode, i.e. most of the GUI programs are not available.

Steps:

1. Set the SecurityProtocol. It is required for https:

[Net.ServicePointManager]::SecurityProtocol = 
  [Net.SecurityProtocolType]::Tls12 -bor `
  [Net.SecurityProtocolType]::Tls11 -bor `
  [Net.SecurityProtocolType]::Tls

2. The actual command, iwr, is an alias of Invoke-WebRequest :

iwr -outf filename https://example.com
