Telnet Client is used to connect to remote machine by using the Telnet protocol. Telnet Client allows a computer to connect to a remote Telnet server and run applications on that server. Once logged on, a user is given a command prompt that can be used as if it had been opened locally on the Telnet servers console. Telnet is disabled by default on Windows7 for the simple reason that it is sometimes used as a callout mechanism by malware, and is generally not used by ordinary users, and thus a good candidate for disabling-by-default. Some programs and features included with Windows, such as Internet Information Services, must be turned on before you can use them. Certain other features are turned on by default, but you can turn them off if you don t use them.

In this version of Windows, the features remain stored on your hard disk so you can turn them back on if you want to. Turning off a feature does not uninstall the feature, and it does not reduce the amount of hard disk space used by Windows features.
