LOL! That's a good one, GS. I feel safe in guaranteeing the driver incompatability issue has been wrestled with by better minds, and there STILL isn't an answer. Fact is, driver incompatability between brands and form factors is a good thing for manufacturers. Good thing = money/sales/exclusivity. Why would company 'A' want their drivers to work on company 'B' equipment? They don't. How many questions on this site alone deal with driver searches? LOTS! Believe me, if a bypass was available someone would have created it and made a boatload of cash off the solution by now.

As for the legality issue and interpretation of the whole drive/computer discussion, why not just email Microsoft and bounce your idea off them? I have no doubt this brainstorm has crossed their collective desk more than once already. My educated guess is that their response will be, "Why of course you can't do that you little whippersnapper!", or 4 letter words to that effect. It's not in Microsoft's best interest to allow anything which resembles running one O/S on multiple computers, even if the particular bypass appears to be used on only one computer at a time. Unless of course a person is willing to come off some cash. Microsoft has that aspect covered, too.

Oh dear, I really opened a can of worms when I spoke out of turn, didn't I?

Let me clarify some things and try to set my own record straight.
NO it does not. The information I gave you does not prove a single thing. I said it was my interpretation which does not necessarily mean it would stand up in court. Please do not take what I say as gospel. (in this instance anyway).

To do it you really need to use Bart Pe this gives you a live system which will work with any hardware. It doesnt support win7 yet but you can do Vista.xp etc.

Without it your drive may not boot as the hardware may be different with every pc

Alright, I'll e-mail them and get the word.

I just realized some thing. Almost every one in this discussion is saying Microsoft frowns upon using an OS on two computers at the same time. Well, what about when I am using Logmein, which is a COMPLETELY legal remote control program? The OS is being used on two computers, one running on the main computer, and a completely different computer using the OS on that computer. You see?

WinPE is exactly, or maybe even better, than what I wanted originally; the ability to boot Windows from a USB stick, and specifically on any computer, because WinPE is designed to work on ANY computer.
