Maintenance windows are a little tricky with software updates. You have to choose among two options that both have pitfalls.
Either you set a deadline and ignore maintenance windows, in which case the update installs at the deadline or the next time the computer is on after the deadline. So basically maintenance windows are useless/ignored. Or you set the deployment to respect maintenance windows, in which case any computer that is not on during its maintenance window - think laptops - never ever patches Unless the user chooses to (ha ha ha! ). In this case maintenance windows help you avoid patching during business hours, but you could end up with lots of unpatched systems to remediate. It is difficult to choose among these two options. It would work much better if it worked how you initially thought it worked ---- If there is a pending software update, install it at the next maintenance window. If the deadline is past, install regardless of maintenance window. This way you could have machines try to install during a maintenance window for a week (or a few days), and if it still didn't find time to install during the preferred maintenance window, it would just install at the deadline (which is the only time WOL packets are sent too, btw) From: [email protected] [mailto:[email protected]] On Behalf Of Jason Sandys Sent: Tuesday, December 09, 2014 4:03 PM To: [email protected] Subject: [mssms] RE: Software Updates & Maintenance Windows: As an additional note here, deadlines are not "lines in the sand", they are absolute lines in concrete. A ConfigMgr client agent will not enforce a deployment until that deployment has reached its deadline (or the user initiates the deployment).

Regards, Gerry From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Orlebeck, Geoffrey Sent: 09 December 2014 17:24 To: '[email protected]' Subject: [mssms] Software Updates & Maintenance Windows: Hello group. I've been working a bit more with SCCM (2012 R2, single primary site) and I have a question surrounding how maintenance windows and deadlines work. I just want to confirmation as I haven't seen this addressed specifically anywhere that I've looked, including TechNet. If I create a Software Update Group today (12/9) and deploy it with a deadline for 12/13 @ 2AM to a collection with a Software Updates maintenance window daily from 11PM-5AM, the updates still won't actually install until the deadline is hit, correct? That is the behavior I am currently seeing in my environment. Even though the devices may download the updates today, and there are maintenance windows that occur nightly from now until 12/13, the updates don't actually install until the deadline is reached. Is that correct? My assumption (I know...assumptions) was the deadline was a line in the sand, but if a maintenance window passes before the deadline and there are pending deployments, those would process. Since this is my first go with ConfigMgr, I just want to confirm the above behavior is by design and that I haven't misconfigured something. Happy to provide any additional details if needed.
