I backed up a number of laptops to virtual machines before they are to be re-purposed, in case I need the data at some later time. While the Physical to VM processes worked fine I am encountering issues on some of the VMs. When I boot them I get an error message saying I MUST activate windows in order to login. This is expected because the hardware changed (from physical hardware to virtualized hardware). I click the OK button and expect to be prompted with ways to activate, windows sits there for quite a while then tells me that "Windows has already been activated". I click OK at that message and get take back to the beginning where I am asked to activate Windows.
I have done some fairly intensive googling but haven't been able to find a real solution.
EDIT: The laptops with the issues are 2 Sony Vaios, I believe that they have the OEM version of the OS originally installed by the factory.
I have tried changing the registry entry where the activation is stored, in order to hopefully make it ask me to specify the product key or something, but that doesn't seem to make a difference. – Daisetsu – 2010-05-14T20:31:31.110
