How can I start Windows Updates on 10 Windows 2016 servers remotely using Powershell

I have 10 domain joined Windows 2016 servers. I need to run Windows updates on them, I don't want to logon on to each of them, and then manually start Windows Updates.

I found that you can do it with;

Install-Module PSWindowsUpdate

But I don't know how exactly.

**** Update; thanks to duenni, this was my final solution. Install PSWindowsUpdate modules and then;

Set-Item WSMan:\localhost\Client\TrustedHosts –Value * -Force

$Script = {import-module PSWindowsUpdate; Get-WindowsUpdate -AcceptAll -Install -Verbose -AutoReboot | Out-File C:\PSWindowsUpdate.log}

Invoke-WUjob -ComputerName s10,s11,s12,s13,s14,s15,s16,s17,s18,s19,s20 -Script $Script -Confirm:$false -RunNow

Solution 1:

As per Release Notes (click on "Package Details") the command Invoke-WUInstall has been replaced by Invoke-WUJob in Version 2.0.0.

Try

$Script = {import-module PSWindowsUpdate; Get-WindowsUpdate -AcceptAll -Install | Out-File C:\PSWindowsUpdate.log}

Invoke-WUjob -ComputerName $computer -Script $Script -Confirm:$false -RunNow

Solution 2:

As a direct equivalent to Invoke-WUInstall you could actually invoke Get-WUInstall using Invoke-Command.

• Make sure you have the latest PSWindowsUpdate.

• Change PowerShell’s Execution Policy to RemoteSigned. The RSEP allows PowerShell scripts as long as they are signed by a trusted publisher. Type Set-ExecutionPolicy RemoteSigned and press Enter. Confirm when prompted.

• For PS 2.0 Import-Module PSWindowsUpdate (not needed after 3.0)

GetWUInstall supports many nice things, but by far the most useful are:

• Get-WUInstall –MicrosoftUpdate –ListOnly --> will list available updates from the Microsoft Update servers

• Get-WUInstall –MicrosoftUpdate --> will ask for each update if to install or not (very useful in recent times)

• Get-WUInstall –MicrosoftUpdate –AcceptAll --> automatically accept all

• adding –AutoReboot --> will also reboot after updating

Many more things are supported like hiding, un-hiding or installing specific KBs. You can use Help Get-WUInstall –full to see all supported features.
