    1. Hi Yoannatan,

      depending on your Windows Version. For Windows 7 ist not easy. Since Windows 8 you can use Powershell instead of dism:

      if((Get-WindowsOptionalFeature -Online -FeatureName "TelnetCLient").State -eq "disabled"){Enable-WindowsOptionalFeature -Online -FeatureName "TelnetCLient"}
      

      Michael
