  Does Windows Product Key Viewer work with Volume License Keys (VLKs) or Multiple Activation Keys (MAKs)?

No, when you run Windows Product Key Viewer it will display the Windows Multi Volume License (VLK) of Windows. Microsoft changed the way MVLKs are handled and no product, not even Windows Product Key Viewer, will be able to display a specific Windows Product Key when it is licensed under a VLK.
Windows Windows 7 and newer VLKs have been replaced with Multiple Activation Keys (MAKs) that either activate copies through a local Key Management Server (KMS), which in turn reports back license usage to Microsoft, or activates directly in communication with Microsoft. Windows Product Key Viewer does not report these MAKs. You might see our product display the License Key as BBBBB-BBBBB-BBBBB-BBBBB-BBBBB
