Working with the team in creating new virtual machine templates I found that some of our Windows 7 templates when they are being deployed with the following error:

Virtual Machine Manager was unable to find a value for the required Sysprep parameter ProductKey. (StatusCode: 610–MandatorySysPrepEntryNotFound)

I attempted to do some google searching which gave me no information for this issue and I started thinking about the issue in detail. Perhaps the sysprep operation requires a key. Then again its right there in the error message which I overlooked at first glance

So I did just that.

I logged into my MSDN and obtained a MAC key, applying it to the template, saved my change and attempted the process again. This time my deployment worked.

I decided to use a KMS Client setup key for these images as our network supports KMS activation.

Another error encountered was:

Virtual Machine Manager was unable to find a value for the required Sysprep parameter LocalAdminCredential. (StatusCode: 610–MandatorySysPrepEntryNotFound)

As we did above we needed to define a local admin account (user/password) to be added to our deployments.
