- Open a command prompt window. Click Start, type ‘cmd’ in the Start Search box, and then press Enter
- Type the following command: pkgmgr /iu:”TelnetClient”
- If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue
- When the command prompt appears again, the installation is complete
