How to enable telnet in windows 10

The telnet client isn’t installed by default. You’ll have to install it from the Control Panel or Command line. Once installed, you can use the telnet command to connect to telnet servers without installing any third-party software. Here I am going to sharing how to enable / install telnet in windows 10.

Once telnet enabled / installed in your system, then we can validate whether application is running or down in the destination server without executing the application url in the browser.

Go to search by click on start windows icon, type cmd, then will see command prompt application, right click on that application and click on Run as Administrator.

To check telnet is whether enabled / installed or not

If the telnet not enable in the system, will get the same following error. It means that telnet not enable in the system.
