I have a number of Windows 7 machines that have been activated using the Volume Activation Management Tool. Some of the machines have since been reimaged and had the confirmation ID reapplied to activate Windows. Most of the machines have reactivated,
but there are some that are not reactivating. Upon closer inspection of the .CIL file saved from the VAMT it appears that the InstallationId field has changed on the ones not reactivating, since reimaging them (Even though there have been
no hardare changes and the same computer name was used).
Does anyone have an idea of what the issue might be caused by?
Thanks in advance for any help.
