Reporting with VAMT

  • Volume Activation by Type - this report list all products VAMT has discovered that have a GVLK installed. The products are grouped by which volume activation type is responsible for activating the product.
  • Not Activated Product Report – list all products VAMT has discovered that are currently not activated
  • Multiple Activation Product Report – lists all products VAMT has discovered that currently have a MAK installed.
  • Duplicate Client Machine ID Report – this report helps to identify machines in the environment which are running images that were not properly generalized by using the Sysprep tool before deployment.
  • At Risk Products Report – lists all products VAMT has discovered that have a GVLK installed and that have fewer than 90 days until license expiration. Machines on this list may be having difficulty communicating with a Volume Activation Authority and are at risk of failing into an unlicensed state.
