I want to enable telnet on Windows 10. I only see a telnet client but not a telnet server. There is a web page telling me to open server manager and do a lot of stuff. But, I don't have a server manager. Please help! I want to enable telnet.

    It might be better to explain exactly why you want to run a telnet server, it's not a particularly safe protocol, its rarely used these days other than in specialist cases such as accessing switches and the like. Just trying to avoid you finding this isn't actually what you want/need. As for why you don't have server manager, I'd expect it only exists in windows server versions, such as Windows Server 2008 and 2012 (and when it arrives 2016). – djsmiley2kStaysInside Jul 28 '16 at 16:17

    The telnet server service was removed from Windows 10 and Windows Server 2012 R2 – heavyd Jul 28 '16 at 16:36
  • To install Telnet Client, run pkgmgr /iu:"TelnetClient". – kenorb Aug 29 '19 at 14:48

Microsoft depreciated Telnet Servers in Windows Server 2012 R2, and subsequently in Windows 10.

Telnet is considered completely insecure these days, because it sends everything across the wire in plain text, so they removed it.

Since you'd need to install a 3rd party Telnet server, you should (instead) consider installing a SSH server. Similar abilities and results, but SSH is generally considered secure.

Perhaps check out this Serverfault question for some suggested SSH servers:

What is a good SSH server to use on Windows?


Windows 8 (2012)

To install telnet in Windows 8, you can use pkgmgr command in the CMD terminal:

Applies To: Windows 7, Windows 8, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Vista

Windows 10

In Windows 10, pkgmgr is deprecated, so use dism instead, e.g.

  • Telnet Client: dism /online /Enable-Feature /FeatureName:TelnetClient
  • Telnet Client: dism /online /Enable-Feature /FeatureName:TelnetServer

To disable, use /Disable-Feature param instead.
