I don't have access to WSUS and Active directory expect for read only access.

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

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

@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:

A AAuthor Commented:
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 CastroEE Solution Guide/Topic Advisor and CEO Faru Bonon ITCommented:
you save the script.
Go to an elevated powershell console.
Navegate to the path where you saved the script.
run the script

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.

A AAuthor Commented:
