i just noticed that there are some new Products added to the WSUS Server that can be synchronized and approved to keep your Azure Pack environments up to date!

SCVMM : Automatic Baseline update script
SCVMM (System Center: Virtual Machine Manager) 2012 and 2012R2 can manage the patch compliance on your servers. That’s a great feature but normally involves some manual work as you have to add each update to the Baselines manually.
My colleague Mikael Nyström (MVP) made a script to handle this automatically, which I’ve developed a bit further.

The script has a few Pre-Requisites;
- A WSUS Server defined in SCVMM
- Approved patches for “Windows Server 2012” and “Windows Server 2012 R2” in WSUS
- Pre-Defined Baselines (you can use Add-Baseline to create them) with these names;
- Security Updates
- Critical Updates
- Updates
- Update Rollups
That’s it! You can now run the script and automatically import all matching updates.
The following actions will be performed;
- Synchronize updates with WSUS
- Check if there are any updates in the Baseline already
- If the baseline is empty, import ALL matching updates
- If the baseline is NOT empty, check the Newest 500 updates and import all matching updates
- Remove inactive updates
- Repeat for all Baselines
- Start a compliance scan
The script will not initiate any remediation. And as the script normally only checks the newest 500 updates, it has to be run fairly regular. In my environment, 500 updates is about 1 month of updates. Though to be safe, run it once a week.
