This script is a somewhat faster means of updating the Media deployment folder (\DeploymentMedia1) when certain kinds of changes are made:
- New/modified applications
- New/modified task sequences
- New/modified drivers
- New/modified packages
- New/modified operating systems
If you need to rebuild the Windows PE image used in MDT (such as a new driver for Windows PE or a change to the IntroScreen.hta file), then you need to run the full update utility. This one, although pretty short, will drive the computer pretty hard while it runs (usually 2-3 minutes). This is, however, much faster than waiting the normal 20-30 minutes for the full media update process to complete.
