Automate the process of applying Windows Updates from WSUS to multiple servers on AWS using RunCommand. Streamline your update management effortlessly. After having updates pushed to all servers from WSUS, in order to avoid the manual operation of installing updates, we can automate this process to a whole lot of servers on AWS using the RunCommand. To apply Updates on WSUS, use the run command.

What to consider when applying WSUS updates
Some prerequisites must be met before applying Windows updates to production servers. They are as follows;
When applying Windows Updates from WSUS, make sure to deploy these updates to the Test-servers-group (Test servers). After applying updates on the test servers, access them via RDP before proceeding to update Production servers.
Other factors that must be considered:
- Pull an AMI of all Production Server AMI (Ensure this is complete before applying windows updates)
- Approve and install identical updates for the test-server-group. Once tested and applied, approve them for Production servers.
Step 2: Proceed to AWS
Access the RunCommand (within Systems Manager and Services) to seamlessly handle Windows Updates from WSUS for efficient management.
Choose AWS-ConfigureWindowsUpdates to enable automatic installation of Windows updates when triggered.

And click on the run. Ensuring the installation of updates and automatic server reboot for seamless operation.
Other information
Note, you can view the status of the run command to see if any failed or succeeded as shown below
Check on the WSUS server after the updates are applied
Check the WSUS console; it should display servers fully patched, as shown below. Furthermore, I confirmed non-problematic updates and accessible servers through Remote Desktop Manager (RDP).
Note: Prerequisites determine an instance’s eligibility or discoverability via the run command. The RunCommand output will look like this below.
