    I don't think you will have any problems doing this. As the product key is what determines whether or not the install is OEM, not the media.
    That was the question. I will work on stating my questions better. I don't want to be accused of pirating Windows again. haha No harm done.

    Thanks.

    BTW, it was mentioned that the only difference between RTM (Retail) media and OEM media is a file called ei.cfg in the sources folder. If you did happen to run into any issues, all you would need to do is modify that file.

    No worries nate, I didn't have any trouble understanding your question. :)
    Thanks, I will try i out. I am getting 3 more copies of the same version (64 bit Pro) this week so it will be nice to use my USB FLASH DRIVE to do all installs.

    I just hope Snuffy understands. He seems to think I may be a pirate.

    That's what I was wondering. I am familiar with that file. I don't see any problems doing it as long as I buy every copy.

    Agreed. It's perfectly legitimate, since all OEM media would be the same anyways.

    I also had almost forgotten about this thread I started a few weeks ago. The question was asked better and answered here too.

    USB install flash drive and different versions

    However, there IS a # just below where it says "Windows is activated" It's the "Product ID #. What generates that #? They are all different on my machines. Even the ones with the same version.

    afaik the product ID is based on the product Key, among other things. It would explain why the PID is different on each computer.

    When you activate Windows, a hardware ID is thrown into the mix.

    That's what has me wondering. The "product ID#" is there before you activate and it's different. Maybe it generates it based on the HW configuration or something. That could be it. No big deal.....I was simply wondering. I will use the flash drive to install Pro from now on and see if it works okay. Then just enter the Windows key when everything is working right. I'm new to this building, but I have done 5 now and have 5-6 more lined up. I enjoy it.

    Yes I would expect the PID to be different even before activating, but I'm not aware of the precise algorithm used. Perhaps someone else could enlighten us on that one
