Deployment Options: When Updates are Applied

• Updates are mandatory if a deadline is specified in the Deployment, and optional if no deadline is specified
• When software updates are deployed to client computers, the software update deployment information is added to the Configuration Manager machine policy, and the client computer becomes aware of the deployment on the next Machine Policy Retrieval & Evaluation Cycle configured on the General tab of the Computer Client Agent Properties. The default setting is every 60 minutes.
• Schedule can be based on local client time or Greenwich Mean Time
  • This is set in the Deployment or Deployment Template
  • Using GMT means updates are applied to all clients at the same time, regardless of local time
  • Using GMT is the default
• When a client receives a software update deployment policy with a configured deadline, it downloads the required software updates and stores them in the local cache. The client will run software update installation from the local cache when the deadline is reached or the installation is initiated manually from the Available Software Updates dialog box. If the software update no longer exists in the local cache at the time of install, it will be downloaded again from the distribution point and then installed.
• The default maximum postponement time is specified in the Deployment Template, and can be overridden in the Deployment Schedule
• If a deadline is specified in the Deployment, updates will be applied automatically at that time on any machines that have not been updated
  • If no deadline is specified, updates will only be applied if the user chooses to apply them
  • Mandatory software updates can be installed on client computers using a configured schedule. This provides the ability to initiate software update installation at a convenient time and install mandatory updates prior to the configured deadline. At the scheduled time, all software updates from mandatory deployments will install. The Install required updates on a schedule setting is on the Updates tab in the Configuration Manager Properties that is opened from the Control Panel on client computers.
  • If Maintenance Windows are applied and the deadline is reached, updates will only be applied during those windows unless the Deployment specifies to allow updates at the update deadline outside the maintenance windows
