    I don’t quite understand your instructions for converting Windows XP Home Edition to Windows XP Professional. I was wondering how to turn my Home Edition to Professional but don’t understand how that can be accomplished from the instructions:

    Open Registry Editor.
    Navigate to HKEY_LOCAL_MACHINE/SYSTEM/ControlSet00X/Control/ProductOptions, where ControlSet00X is the one with the highest number.
    Delete the ProductSuite registry key.
    Then, create a new DWORD value and named it as Brand.
    Set the “Brand” value data as 0.
    Reboot the system.
    On boot up after the BIOS screen, press F8 to display Windows XP Startup Menu.
    Choose Last Known Good Configuration (LNG) and hit Enter

    If mine is XP Home Edition and was installed from MS CD (Home Edition) how can making the registry changes and restarting to LNG convert that original installation to Pro?
    I would appreciate an explanation before making such changes,
    Richard
