 This policy is used to enforce using non-admin accounts while creating a lab. With the August 2022 Update, you can choose to add a non-admin account to the VM image.  This new feature allows you to keep separate credentials for VM admin and non-admin users. For more information to create a lab with a non-admin user, see [Tutorial: Create and publish a lab](tutorial-setup-lab.md#create-a-lab), which shows how to give a student non-administrator account rather than default administrator account on the “Virtual machine credentials” page of the new lab wizard.  
 
 During the policy assignment, the lab administrator can choose the following effects.
