+  * For Windows Server only, an available security update patch that is not approved by the patch baseline can have a compliance value or `Compliant` or `Non-Compliant`, as defined in a custom patch baseline. 
+
+When you create or update a patch baseline, you choose the status you want to assign to security patches that are available but not approved because they don't meet the installation criteria specified in the patch baseline. For example, security patches that you might want installed can be skipped if you have specified a long period to wait after a patch is released before installation. If an update to the patch is released during your specified waiting period, the waiting period for installing the patch starts over. If the waiting period is too long, multiple versions of the patch could be released but never installed.
+
+Using the console to create or update a patch baseline, you specify this option in the **Available security updates compliance status** field. Using the AWS CLI to run the [create-patch-baseline](https://docs.aws.amazon.com/cli/latest/reference/ssm/create-patch-baseline.html) or [update-patch-baseline](https://docs.aws.amazon.com/cli/latest/reference/ssm/update-patch-baseline.html) command, you specify this option in the `available-security-updates-compliance-status` parameter.
