powershell script

Does anyone know how to pull outstanding windows updates report for all AD computers with a PowerShell script?
I don't have access to WSUS and Active directory expect for read only access.

Thanks.

Can you define "Outstanding patches"? Pending, applied or others?.

Pending Patches. if possible I would also like to see applied, successful and failed patches? I want to run this against all AD devices.

Thanks

WUU utility is for applying patches. I am not looking to apply any patches. All I need to see is pending updates for all active directory devices.

Jose, I am unable to run this script. does this script works for you?   how do I save this is csv file?
I am getting this error:

Get-PendingUpdate : The term 'Get-PendingUpdate' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was
included, verify that the path is correct and try again.
At line:1 char:1
+ Get-PendingUpdate -ADcomputer


Can you please verify is this is correct:

@OP: Take a look here, it seems to query all devices on an AD for pending updates. There are some pre-reqs but they're also listed in the TN Gallery:

or is there any script I can from sccm to find out windows updates. can I use sccm client to find out pending updates from all AD computers. again I don't have access to wsus server. I would like to see 20+  and 50 + , pending patches in csv file.
Jose Gabriel Ortega Castro

you save the script.
Go to an elevated powershell console.
Navegate to the path where you saved the script.
run the script
 .\Scriptname.ps1

Open in new window

And check the results.
if you obtain an output you can use this
 .\Scriptname.ps1 | Convertto-csv | out-file here.csv

Open in new window

Thanks Jose. I will try that. I am also looking into clients not getting patches from WSUS. what could be the reason? over 500 clients are not getting patches. They are active and logging in to the system. what is stopping these machines to get patched.

Thanks.
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.
