Supplemental Guidance
Using automated tools to support patch management helps to ensure the timeliness and completeness of system patching operations.
Practitioner Notes
Use automated patch management tools that can detect, download, test, and deploy patches with minimal manual intervention.
Example 1: Configure WSUS with automatic approval rules for critical and security updates. Patches are downloaded from Microsoft, approved based on classification, and deployed to production machines on a defined schedule — all without manual approval for routine updates.
Example 2: Use Azure Update Management or Intune to automate patching for cloud and remote machines. Define maintenance windows, set up pre-deployment testing groups, and let the tool handle deployment and reporting. Focus your team's time on exceptions rather than routine patching.
