    Hi. RTM means Release to Manufacturers. That is the OEM version. I don't understand what you meant.

    This is the only defference between the OEM and Retaild isos

    ei.cfg of Windows 7 RTM retail ISO:

    [EditionID]
    Ultimate
    [Channel]
    Retail
    [VL]
    0

    ei.cfg of Windows 7 RTM OEM ISO:

    [EditionID]
    Ultimate
    [Channel]
    OEM
    [VL]
    0

    The ei.cfg file is to be found in the /sources directory

    best just to delete ei.cfg then you can install any version.

    run slmgr -dlv you will find details about your activation state also whether 7 is retail or oem. To change from retail to oem all you have to do is mod your bios and use a matching certificate and any oem:slp key, or use a loader you will have OEM 7. To have retail you just have to buy a copy from a software retailer /have a msdn subscription or higher etc etc.... you get a retail key.

    Hope that helps :)

    This might be a stupid question but altering or deleting the ei.cfg file will not change the hash, will it?:eek:

    You can have any type of OS installed, system will freeze because of the hardware you have, not the OEM or retail version of the OS.
