Get-WindowsUpdatePolicy

 

Windows UpdateI’ve been working on a project to roll out automated patching to the servers in our environment. We have been using a combination of group policy and WSUS, which is a great solution, but it doesn’t allow for multiple maintenance windows. Since we are primarily a Windows shop we chose to use System Center Configuration Manger (SCCM) as our solution. If you’ve worked with SCCM you know that “it’s a full time job.” So over the last few months we’ve been carving off some servers from our WSUS and moving them to SCCM for patching. During the changeover we needed to verify if the server was  actually talking to SCCM instead of our existing WSUS infrastructure. For the first few servers I logged on and launched regedit.exe to look at the policy key HKLM\Software\Policies\Microsoft\Windows\WindowsUpdate. After doing this two (too many) times I realized this wasn’t going to scale. I put together a PowerShell script to read the registry keys we needed from one or more remote servers.

Introducing Get-WindowsUpdatePolicy

Now with a quick command I can see what WSUS server a computer is configured to use. Try it out, and let me know if you find it to be useful.
