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.
