Worklet - Windows Update Component Cleanup

This worklet takes advantage of starting Windows Component Cleanup on command with output in the Automox Activity Log. This will clean up only if the updated components is older then 30 days.

In the example output you can see this process cleaned up 1.28 GB of space.

Optional change to clean everything – Add /ResetBase after the /StartComponentCleanup switch. The /ResetBase switch option also deletes all superseded versions of every component in the component store. A warning if you want to use it on systems in production ⛔ All existing service packs and updates cannot be uninstalled after this command is completed .
