The following list contains the current known issues with the Volume Activation Management Tool (VAMT) 2.0.

  • The VAMT Windows Management Infrastructure (WMI) remote operations may take longer to execute if the target computer is in a sleep or standby state.

  • Recovery of Non-Genuine computers is a two-step process. The VAMT can be used to install a new product key and activate the computer. However, the computer itself must visit the Windows Genuine Advantage Web site ( to revalidate the computer's Genuine status. Upon successfully completing this step, the computer will be restored to full functionality. For more information on recovering Non-Genuine Windows computers, see the Volume Activation technical guidance:

  • When opening a CIL file saved in a previous version of the VAMT, the edition information is not shown for each product in the center pane. Users must update the product status again to obtain the edition information.

  • A CIL file saved by previous versions of the VAMT should not be imported into VAMT 2.0. Instead, any files created with previous versions of the VAMT must be opened in the VAMT 2.0, and users are advised to update the licensing status again for the computers and save the refreshed result into a VAMT 2.0 CIL file.

  • The remaining activation count can only be retrieved for MAKs.

  • To install a KMS client key on a Windows Vista computer, you must first import the CIL file (located in \Program Files [or Program Files (x86)]\VAMT 2.0\GVLK\GVLK_Vista.CIL). From the Add Product Key dialog, select the GVLK which matches the edition of Windows Vista, in the same way you would select a MAK.

  • VAMT will discover and display status for OEM licensed products. However, VAMT does not support activating an OEM licensed product.
