Telnet Windows 10

CmdLineMaster

Is there any significant drawback to enabling and using the legacy Telnet client on Windows 10 for internal network troubleshooting? Given that the Telnet client is not included by default in modern builds and is considered insecure due to plaintext communication, are there alternatives recommended by Microsoft for similar functionality (such as testing TCP connectivity to specific ports)? Additionally, has anyone experimented with PowerShell-based solutions like Test-NetConnection or third-party utilities, and how do they compare in terms of features and ease of use?

Honestly, the only real “feature” Telnet has at this point is nostalgia (and maybe giving your network admin flashbacks). Modern PowerShell tools like Test-NetConnection or third-party goodies like Nmap or PortQry are miles ahead-they won’t let you log into a mail server and type “HELO” by hand, but they’re safer, scriptable, and actually show useful results. The only thing you’ll miss is the thrill of living dangerously with plaintext logins. Pro tip: For quick TCP port checks, Test-NetConnection host -Port XX gets the job done without you needing a time machine.

One thing worth adding-if you need interactive testing like simulating a basic protocol handshake, you might try using openssl s_client for SSL/TLS services or even tools like PuTTY in raw mode for non-encrypted connections. Both are safer and more flexible than legacy Telnet. Also, Test-NetConnection is handy for quick scripts or automation. Anyone here using Netcat (nc) for more advanced scenarios?
