Date of most recently installed update

Hi All,

I'm looking for a PowerShell script that help me manage my Windows servers who receive updates from our internal WSUS server. We are using WSUS 3.0 running on a single Windows 2012 R2 machine.

In simple terms, I need a PowerShell script that can produce a simple table showing the following:

1. The date of the most recently installed update for each server
2. Email these results to a specified email address.

I am not interested inwhich update was installed – I am only concerned about when the last update was installed on each server.

I have seen a very good script posted by Aman Dhally on his IT blog, the script does exactly what I need (minus the emailing part), but it only returns results for the machine where the script is run from, here is the script:

First enter:

$windowsUpdateObject=New-Object-ComObject Microsoft.Update.AutoUpdate

Then enter:

$windowsUpdateObject.Results

This produces a very simple table showing the date of the last successful update that was installed.

(to my frustration I cannot post URL's or images of the result, as my account has yet to be verified!)

What I would like is for the above to query a list of my Servers and produce the results exactly in the same way as above, one line per server. So column 1 =computername, column 2=LastSearchSuccessDate, column 3=LastInstallationSuccessDate

For example, I have a text file: C:\Computers.txt, which contains a list of all my Windows Servers. Would it be feasible to produce a script that could say get-content c:\Computers.txt and for each computer listed, show me the date of the most recent Windows Update that was installed?

I hope this makes sense, I’d be grateful for any assistance. I should add that I’m a PowerShell newbie, so there is still a lot to learn for me.

Many thanks
