Offline Image Servicing in ConfigMgr 2012 SP1

Within ConfigMgr it's possible to inject software updates in a reference image. This feature is called Offline Servicing. That way a default Install.wim can be used and updated within ConfigMgr without using a Build and Capture task sequence. It's really a great feature, which saves you multiple hours updating images with monthly updates. It will probably take multiple hours to mount the image, inject the updates and unmount the image again. Don't forget the last step needed after Offline Servicing: Update the Distribution Point (as usual). This because the proces doesn't do that for you. Otherwise the reference image will be deployed again, and no updates will be seen in Windows. This has happened to me more than once, so take advantage of this.

On the image properties Installed Updates can be seen. There's a tab for Servicing also, to see which updates are scheduled.

After deploying the image, software updates will be displayed in Control Panel as usual. No difference at all with a default installation.
