I’ve seen a few examples of distributing a set of teams backgrounds to users in MEM, mostly they seemed a little overly complex, especially in targetting all local users and/or packaging the script into an application. I wanted to:

• Deploy using MEM PS script in user context
• Avoid access controls on the storage location of the backgrounds
• Simplify the creation of required Azure resources
• Have a simple update procedure
