If you ever have the need to Manually Download Updates with SCCM (like with a zero day exploit deployment) I will show you how to below. This helps even if updates haven’t been downloaded automatically by the Auto Deployment Rule.
Open your SCCM console and go to Software Library, then expand Software Updates and then click on All Software Updates.
Let the list populate and select the updates that want to download, then right click and choose Download.
It will then prompt your to Select a Deployment Package. Click Browse.
Select the Auto Deployment Rule that you use for your monthly patch deployments and then click on OK.
Once the deployment rule had been selected, click on Next.
Now choose to Download software updates from the Internet.
Choose the required update language then click Next.
Now you should be ready to download the updates you have selected. If ready to do so, click on Next.
Your updates will start downloading. Note that this may take some time to complete the downloads.
Hopefully all went well and your updates are now ready to be deployed.
This is a great way to download updates really quickly and make them available to deploy them to your desktops and servers. Click the link to see another great post on how to create a SCCM Automatic Deployment Rule.
