Hey Checkyourlogs fans,


Today I peeled out and updated part of my BigDemo Script that builds Base Images for my lab as a Standalone Script.

It’s called BaseImageBuilder.PS1 and the source code can be found at:

The cool part about this script is that we have added a couple of cool new functions. One of them is a UI Prompt that will ask

where your ISO’s are located. This is so much easier that having to type in a path.


Now automatically downloads the January 2018 Cumulative Update for Windows Server 2016 and apply it to the Gold VHDx.


With this you can enjoy your Hyper-V Images with a fully patched and service experience.

As always, we really hope you enjoy this.

Happy Learning,


Dave Kawula – MVP
