I'm experiencing certain issues with the built-in OpenSSH client that, according to the Win32-OpenSSH Github page, seem resolved in newer versions. The newest version is v7.9 while the preinstalled client is in version 7.6p1.

PS C:\> ssh -V
OpenSSH_for_Windows_7.6p1, LibreSSL 2.6.4

I understand it's possible to install OpenSSH both as an optional feature in the "apps & features" settings page, or using Powershell. That seems futile in my situation as the client clearly already is installed.

PS C:\>  Get-WindowsCapability -Online | ? Name -like 'OpenSSH*'

Name  : OpenSSH.Client~~~~
State : Installed

Name  : OpenSSH.Server~~~~
State : NotPresent

Unfortunately, it doesn't seem possible to update the client this way and the Github page doesn't seem to publish binaries. Does this mean I have to make the binaries myself if I want to use newer versions, and would they even work as a replacement not being signed or anything? Is there maybe a simpler way?


This page gives the steps to follow using Powershell to install the latest packages.

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
$url = 'https://github.com/PowerShell/Win32-OpenSSH/releases/latest/'
$request = [System.Net.WebRequest]::Create($url)
$([String]$response.GetResponseHeader("Location")).Replace('tag','download') + '/OpenSSH-Win64.zip'  
$([String]$response.GetResponseHeader("Location")).Replace('tag','download') + '/OpenSSH-Win32.zip'

If you use Chocolatey, then type the following in the command prompt as shown here:

choco upgrade openssh

    You will likely want to use the instructions on this page to install the update. However, I would perform test within a virtual machine, to verify what actually happens. Unless there is a vulnerability you are specifically worried about, you might not want to attempt to manually update the install, and instead, remove the built-in version and use the above installation instructions. – Ramhound Jan 19 '19 at 0:54

The binaries are now on GitHub. Download the latest and update them in C:\Windows\System32.

  • On the page you linked to I only seem to find source code in zip or tar.gz format, no binaries. – vic May 27 at 14:30
  • You are correct, apologizes. I have updated the link. – Cez Chi May 27 at 15:48
