Vista x64 Ultimate I installed updates on April 16, and the next day I started receiving notifications that my copy of Windows is not valid at bootup. It is a standard WGA situation: I have the option to activate later, my desktop is black (except for the works Vista Build 6001, This copy of windows is not genuine). Vistaloader has not resolved the issue--it is not changing the OEM information, for some reason, or its doing so unreliably. Even when it does, after a restart, it gives me the same notice. Any ideas or can I be pointed in the right direction? Thank you.
