Below is the VDI Cleanup script that I’ve been using over the years. I thought I’d post this after setting up a Horizon Lab environment. I shared it earlier in the year on Reddit, and had some good suggestions which I used to update the script. The script has been taken from other blogs over the years and just edited further and further for my own/customers needs.

Optimizations to any master are done using the VMware OS Optimization Tool.

I personally just run this as bat file to clean up and shut down the master template as a final step each time I make an update.

You can find the script on Github here, or below.
