Windows Defender Credential Guard
Answer: Credential Guard is supported on Windows Enterprise and Education editions. It uses virtualization-based security to isolate secrets; support still depends on compatible hardware, firmware, and platform configuration.

Use the curated answer as a starting point, then prove the outcome against the target tenant or device.
What it means
- Credential Guard protects derived credentials by isolating them from the normal operating system
- Windows Pro is not listed as a supported edition in Microsoft's current edition table
- Some authentication protocols and credential-delegation scenarios require compatibility review
What to check next
- Confirm the installed edition is Enterprise or Education and the device meets virtualization-based security requirements
- Inventory applications and authentication flows that rely on protocols or credential delegation affected by Credential Guard
- Pilot the policy and verify the running state rather than assuming that a configured policy is active
Verify success
- Confirm the feature is present or enabled on the target edition and build.
- Test the intended workflow with a pilot device and least-privileged user.
- Confirm policy reports success from the actual management authority.
Escalate when
- The documented edition and hardware requirements are met but the feature is absent.
- Policy reports success while the user or device state is incorrect.
- Licensing or OEM terms—not technical prerequisites—control the outcome.
