Windows system computer/server prompts "not an internal or external command, nor an operable program or batch file" when running the CMD command prompt. What should I do in this situation? Share the solution with you today.
Solution
Enable Windows features (Windows 10 system is demonstrated)
1. Start - Control Panel - Programs and Features
2. Enable or disable Windows functions - check "Telnet Client" or "Telnet Client", click OK
3. After clicking OK, wait for the system to make changes, and it will prompt that Windows has completed the requested changes, indicating that it has been enabled successfully. 
The above is the solution to "telnet is not an internal or external command, nor is it a runnable program or batch file". I hope it can help you~ If you have any questions, please leave a message and send me a private message. or contact me home page avatar
