What it does

Specifies whether Automatic Updates should automatically install certain updates that neither interrupt Windows services nor restart Windows. If the status is set to Enabled, Automatic Updates will immediately install these updates once they are downloaded and ready to install. If the status is set to Disabled, such updates will not be installed immediately. Note: If the "Configure Automatic Updates" policy is disabled, this policy has no effect.

What it writes

Hive: HKEY_LOCAL_MACHINE
Registry key: Software\Policies\Microsoft\Windows\WindowsUpdate\AU
Value name: AutoInstallMinorUpdates
When enabled: DWORD 1
When disabled: DWORD 0

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
