Microsoft no longer includes certain features to windows systems starting from windows vista by default. It is still available but must be installed or enabled by the user. The normal way to enabled these features is through the “Turn Windows features on or off” window found in Control Panel. This accomplishes the task but can be annoying when you are working in Command Prompt and need to use the telnet command immediately.
Instead of going to Control Panel, the following way is considered better by many administrators (including me). Simply run this command with elevated administrative rights at the command prompt:
dism /online /Enable-Feature /FeatureName:TelnetServer
The Telnet Server should be immediately available after the dism command has successfully been completed.
