With non-domain joined machines, and access to Active Directory being restricted, administrators need new methods for optimizing environments easily. Luckily Citrix provides a new method for this optimization, Workspace Environment Management 2212 and Service.
To get you started with a template similar to the one I provided for GPO here are starter templates for Actions and Settings for WEM that match the best practices in the previous template.
Make sure to look at the GPOs for HKLM and HKCU and ensure that you put in your environment info that is called out there.
To use these items, just create a new Configuration Set, unzip and import the Actions and Settings to that Configuration Set.
