 | **Scenario** | **Pros** | **Cons** |
 | --- | --- | --- |
 | **Pre-provisioned** | • Faster for user since IT admin/OEM/reseller handles bulk of device ESP during the technician flow. | • Requires interaction by IT admin/OEM/reseller.  <br/>• Requires [TPM attestation](https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/manage/component-updates/tpm-key-attestation) during technician flow so only works on physical devices with supported TPM (doesn't work in VMs even with virtual TPM).
