how to request a mak activation count reset after repeated re imaging?

Question

Dear Microsoft licensing support,

I would like to request assistance regarding our organization's Multiple Activation Key (MAK).

We have been using this key to activate Windows installations across our environment for some time without any issues. Recently, however, we discovered that the remaining activation count has been depleted much sooner than expected. After reviewing our deployment history, we believe the increased usage is primarily the result of repeated operating system re-imaging and hardware replacement activities performed during device refresh and troubleshooting.

Our understanding is that each reinstallation or significant hardware change may consume an additional activation, even when it involves the same physical device. As a result, we are now unable to activate newly deployed systems using the existing MAK.

We have confirmed that:

The key is being used only within our organization.

We are not sharing the key outside our licensed environment.

The increase in activation usage appears to be related to legitimate redeployment activities rather than an unexpected spike in device count.

We have not intentionally exceeded the number of systems covered by our licensing agreement.

Before requesting a replacement key, we would like to understand whether Microsoft can review the activation history for the existing MAK and determine if an activation count reset or increase is appropriate in this situation.

We would appreciate any guidance on the recommended process, including whether additional licensing information or proof of ownership is required to submit such a request.

Thank you for your assistance.

Hi Tobias,

You’re right that repeated re‑imaging and hardware changes can consume additional MAK activations, even when it’s the same physical device. The good news is that Microsoft does allow organizations to request a review and reset of MAK activation counts when usage is tied to legitimate redeployment activities.

The recommended process is to open a support case with Microsoft Volume Licensing Support or your licensing reseller. You’ll need to provide the MAK key details, your licensing agreement information, and a short explanation of why the activations were consumed faster than expected. Microsoft can then review the activation history and, if appropriate, reset or increase the activation count for your existing key. In some cases, they may issue a replacement key instead.

It’s also helpful to include proof of ownership (agreement number or license certificate) and a description of your deployment practices, so the support team can quickly validate that the usage aligns with your entitlements. Once the request is approved, the reset is applied on Microsoft’s back end, you don’t need to make changes to your environment beyond re‑activating the affected systems.

For future deployments, you might consider using Key Management Service (KMS) instead of MAK if you have a large number of devices, since KMS avoids consumption issues during re‑imaging.
