    hello guys, I just have few small questions, hope someone can answer them:
    Windows 7 Ultimate is activated on my computer via BIOS mod.

    1. Is it possible to change Win7 Ultimate to Win7 Professional without installing the whole OS again? I am thinking about changing to a retail key or SPL key

    2. If I decide to purchase a retail key what commands are needed in cmd in order to deactivate the offline activation and to enter a retail key?

    Thanks in advance;)

    change "ProductName" from "Windows 7 Ultimate" to "Windows 7 Professional" in HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion. Finally put in ur Win7 install dvd and "Upgrade"....

    sometimes you need to change the product version also in the same registry location

    And exactly why would you want to do this, since it would be a downgrade?

    I dunno but if they want pro why not just use windows7_iso_image_edition_switcher or eicfg_removal_utility before install. Maybe their just curious...lol

    Because I don't want to sell a computer with a OS on it that isn't on the sticker on the back.
