Hi pc-88, no, blocking the running of an app using AppLocker will not prevent it from being provisioned for additional accounts (or installed). Removing apps depends on how exactly they were installed and/or provisioned in the first place. The general common practice that most orgs adopt for removing built-in apps is to run a script after Windows provisioning to remove them or to use Intune to deploy uninstalls for the apps (also after provisioning).
Jason_SandysThanks. Am I correct in understanding that the Windows provisioning process is complete after OOBE is finished, and you've reached the Windows login screen?

The device portion of the provisioning process is complete, yes, however user provisioning won't happen until the user actually logs in for the first time.

Jason_Sandys I guess I don't fully understand the provisioned vs installed definitions here and I can't quickly find a good reference that explains the difference. Is an app only "provisioned" when there is a Windows provisioning package for it and a user logs in for the first time? Is an app only "installed" when an EXE/MSIX/etc installer is run by a user or an MDM?
