I guess there was some misunderstanding. I was running vista upgrade and bought windows 8 pro disk. Windows 8 does not sell a full version, only an upgrade. It appears that there is no way to load win 8 X 64 bit unless you are already running a 64 bit prerequisite program. This is a huge oversight by Microsoft. I predict the CEO will be fired and sent to Siberia. I know about the requirements for running 64 bit and my computer is capable of handling it. I also know that a 32 bit OS can only handle 4 gigs RAM, a 64 bit OS can run a much higher memory. Handling video editing has a huge resource demand and 64 bit is almost a necessity. so far I'm almost ready to use my windows disks as Frisbees. Hey Microsoft, how about a service pack to put the control icons back where they were. It's frustrating and maddening to not know where to turn the computer on or off or not be able to escape the Microsoft "store", how about a little X in the upper r h corner. It's like going to a store and they lock the door until you buy something.
