You can use the Volume Activation Management Tool (VAMT) to install retail, MAK and KMS host keys.
- Open the VAMT Microsoft® Management Console snap-in
- Click All Products or any sub-node and choose the
- Choose Install Product Key from right-click
context-sensitive Actions menu, or from the Action
menu on the top menu bar, or from the Selected Items menu in
the right-hand pane. The VAMT will display the available product
keys in the next dialog box.
- Select the product key you want to install and click OK.
Note that only one key can be installed.
- The VAMT displays the Installing product key progress
window while it attempts to install the product key to the selected
products. When the process is finished, the status will appear in
the Action Status column of the progress window. Click
Close to close the progress window.
The same status is shown under the Status of the last action column in the product list view in the center pane.
Product key installation will fail if mismatched key types or editions are found. The VAMT will display the failure status and continue the installation for the next product in the list.

The VAMT stores product keys in plain text in a full-save Computer Information List (CIL) file. Access to the VAMT, especially to the CIL files that may contain your organization's product keys, should therefore be limited to administrators.
