đź“‘Advantages of disk imaging:

The primary benefit of imaging is that it allows you to build a single reference system optimized for your specific environment and then record that configuration for use in other places. This technology allows you to "bake in" preconfigured programs and settings for easier rollouts.

If an image is delivered to many computers, all of those computers will retain the original device's settings, applications, and customizations. The IT department won't have to spend as much time on mundane tasks like software setup, printer configuration, file duplication, etc.
