Hi Zac H,
By default, Patches are installed according to Maintenance Windows, Default SWU Policy schedule is disregarded in that case. As far as those computers have an always open Maintenance Window, Patches will be installed ASAP on them.
To make patches install on custom schedule, You should select "Override Maintenance Windows settings" checkbox in the Default Software Update Plug-in Policy. Note, that this policy can be cloned and then targeted to the desired group of computers, to leave all other endpoints obey Maintenance Windows.
Regards,
Serge
