WSUS has no option for syncing once per month. It requires a daily synchronization. Is it possible to change this to once per month through GPO or other means? Is the only other option to manually sync?

    I don't know why you would want to do that. The files don't download a second time.. having them available locally as quickly as (reasonably) possible is a good idea. – Tim Brigham Jun 08 '18 at 17:38
  • Microsoft releases new updates the second Tuesday of every month. It's pretty rare for an update to be released "out of band". Assuming your WSUS server has completed a "full" sync at least once, then it should only be downloading new updates once a month every month. There's no need to try to "hard code" it to do so. – joeqwerty Jun 08 '18 at 18:48
  • I believe you can start a synchronization via the WSUS API, so you could write a script and configure Task Scheduler to run once a month. – Harry Johnston Jun 11 '18 at 01:39

    @joeqwerty, there's a second set of updates most months. And I don't think one-off updates are quite as unusual as you suggest, particularly when updates have to be re-released due to some problem or other. As for the reason the OP wants to do this, I'd be prepared to make a *small* bet that it is so they can use automatic approvals but still be sure the clients will only reboot once a month. :-) – Harry Johnston Jun 11 '18 at 01:43
  • @gibsonfirebird12, glad to hear it. If you get it working, please consider posting the script as an answer. – Harry Johnston Jun 11 '18 at 05:29
  • @gibsonfirebird12 - I noticed that you did not respond to my answer! Is there anything which you'd like me to query further? Any improvements, etc. required? – Am_I_Helpful Sep 22 '18 at 14:59
  • This makes little sense - one thing overlooked is that it is not only updates, it is also anti virus and malware signatures that WSUS handles. Those come basically multiple times per day. – TomTom Feb 13 '21 at 10:40

You cannot achieve this directly from the native GUI of WSUS. It is not available as an option. Instead, you can extend the capabilities of WSUS with a third-party application like SolarWinds Patch Manager.

Is the only other option to manually sync?

Preferably, if you've to, a better hack would be to set to manually perform the synchronisation in WSUS. And, then create a Windows task scheduler which would perform synchronisation with the help of available WSUS API. For more information, please refer to the post "Synchronize WSUS update using command".
