    Hi.
    Yesterday I read (either in this forum or somewhere else, maybe in a torrents site) how to make the installation of Windows 7 build 7100 RC allow the upgrade from a beta.
    Now I need it and I can't find it...
    Thanks

    Found it (sorry)

    To upgrade from beta you need to:

    - Extract the .iso contents to a storage location you wish to run the upgrade from (a bootable flash drive
    or a directory on any partition on the machine running the old build).
    - Browse to the sources directory.
    - Open the file cversion.ini in a text editor like Notepad.
    - Modify the MinClient build number to a value lower than the down-level build. For example, change 7100 to 7000.
    - Save the file in place with the same name.
    - Run setup.exe like you would normally and the version check will be bypassed.
