Hi Amr,

To address the issue of a leaked MAK key, follow these steps to block the key from further use and invalidate any unauthorized activations:

1. Contact Microsoft Support:
   • Immediately report the leak to Microsoft Volume Licensing Support. They can assist in blocking the compromised MAK key and provide guidance on the next steps.
   • Provide details about the leak and request that the MAK key be deactivated.
2. Block the MAK Key:
   • Microsoft can deactivate the MAK key on their servers, preventing any further activations.
3. Generate a New MAK Key:
   • Request a new MAK key from Microsoft. Ensure the new key is securely stored and only accessible to authorized personnel.
4. Revoke Unauthorized Activations:
   • Microsoft can help you identify and revoke unauthorized activations. This process might involve auditing the current activations associated with the compromised MAK key.
5. Use Key Management Service (KMS) Instead:
   • Consider switching to a Key Management Service (KMS) for activating Windows in your organization. KMS requires periodic reactivation within the organization, reducing the risk of key leakage.
   • Configure KMS on a server within your organization and ensure all clients are configured to use KMS for activation.
6. Monitor and Audit:
   • Implement monitoring and auditing processes to track activations and ensure compliance.
   • Regularly review activation reports and take action on any suspicious activity.

Steps to contact Microsoft Support:

1. Visit the Microsoft Volume Licensing Service Center:
   • Microsoft Volume Licensing Service Center
2. Log in with your organization's credentials.
3. Contact Support:
   • Navigate to the support section and open a support ticket or use the provided contact information to report the issue.

By taking these steps, you can prevent further misuse of the leaked MAK key and revoke any unauthorized activations that have occurred.
