How can you automate patch management with PowerShell

Question

Managing patches across multiple Windows machines manually has become increasingly time-consuming, and I’m exploring automation via PowerShell. My goal is to create a script that can:

• Identify missing patches or updates on target systems.
• Download and install the required patches.
• Log the actions taken and handle errors gracefully. I’m looking for advice on best practices, recommended modules or cmdlets, and any sample scripts that could serve as a starting point. Guidance on scheduling and integrating this process into our existing infrastructure would also be appreciated.
