Last steps and image sealing
I like to apply configurations at build and enforce them with a GPO if needed, I don’t only like to rely on GPOs. In our packer template we are applying 2 configurations. One if to set the app-v agent so that we can push packages after the image is deployed and the other config is our image sealing script. In this page we break down the last steps in our packer template.
I like to create an image sealing process to add optimizations and generalize the image. For example if running on Citrix MCS you’d want to turn off Windows updates. If you install OneDrive in a corporate network you might want to disable user’s from login in to their personal ones so the last script will check and apply the settings.
In this last step you can add Citrix Optimizations, desktop icons, registry keys and others that will make your image and user experience the best.
