This Powershell command will install a Windows feature on your Windows 8.1 or server 2012 machine. I am only using the telnet server as an example.
PS C:\Users\Administrator> Install-WindowsFeature telnet-server Success Restart Needed Exit Code Feature Result ------- -------------- --------- -------------- True No Success {Telnet Server}
This is how easy it is to install a Windows feature using the command line. This is a very good way to setup a Windows server machine using Powershell.
