Hi I just got a new Compaq notebook with Windows 7 Professional 32-bit preinstalled. I would rather have the 64-bit version installed. I had a 64-bit pro (X15-65805) (retail?) disc handy and tried to install it with the OA MEA key (the one under the notebook). Unfortunately that key did not work, so I just continued the install without a key. In addition I cannot use the HP Recovery function the restore the original 32-bit. I still have the .wim so I could use imagex to restore the image again I guess. So my question are: 0) If I change the X15-65805 disc from retail to oem would it work with the OA MEA key? 1) If not, would it be possible to install 64-bit with the OEM SLP key (used in the 32-bit .wim)? 2) If so is there an easy way to extract the key directly from the .wim? 3) How do I go about making a 64-bit DVD with the slip key integrated so I don't have to activate and how should the ei.cfg look like? Of course I'll be happy to share the OEM SLP key extracted.
