Hello Megacore ,
Thank you for reaching out to the Microsoft Q&A community.
The message “3 of 3 Windows Server 2022 activations used” indicates that the Multiple Activation Key (MAK) you are using has reached its maximum allowed activation count. This commonly occurs after Windows Server is reinstalled or reactivated, even on the same hardware, as each activation attempt consumes one count from the MAK activation limit.
To resolve this issue, you will need to contact the Microsoft Licensing Activation Center to request an increase or reset of the activation count for your license. Microsoft support can verify your license and assist with extending the available activations.
You can find the appropriate contact details for your region here: https://www.microsoft.com/Licensing/existing-customer/activation-centers
For reference, Microsoft documents this behavior under activation error 0xC004C020, which explains that the error occurs when a MAK exceeds its activation limit: https://learn.microsoft.com/en-us/troubleshoot/windows-server/licensing-and-activation/troubleshoot-activation-error-codes
When contacting the Microsoft Activation / Licensing Center in Ecuador, calls may initially be answered by an automated system with recorded instructions. If the issue cannot be resolved automatically, you may request assistance from a support representative.
However, Microsoft recommends using the online support channel to connect directly with a licensing support executive, instead of repeatedly calling the phone line.
Official recommended approach
Go to Microsoft Support – Contact Us https://support.microsoft.com/contactus
Sign in using the Microsoft account associated with your license (or your organization’s business account).
Select:
Product: Windows / Windows Server
Issue: Activation & Licensing
Choose one of the following support options:
Request a call back (Microsoft will call you)
Chat with a support agent
This method completely bypasses the automated phone system, and your request will be handled by a live support executive who has the authority to review your license details and assist with activation issues.
Prepare the following information to get faster assistance
Microsoft recommends having the details below ready before opening a ticket or speaking with support:
License Agreement Number (EA / Open / CSP, if available)
Product Key (MAK)
Installation ID (from the activation screen or slmgr /dli)
A brief description of the issue, for example:
The server operating system was reinstalled
Activation fails with the message “3 of 3 activations used”
Using the online support option is the most effective way to resolve this type of licensing issue and receive direct assistance from Microsoft. *
