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.
