Upgrade Windows 7 RC to RTM

09/09/2009 Leave a comment

Although Microsoft says it is not possible to upgrade Windows 7 RC (or beta) to Windows 7 RTM it is possible with a little tweak to an installation file.

This is how it’s done:

1. Copy the contents of the ISO or DVD to a separate storage location (such as a bootable USB storage device, a separate partition or whatever)
2. Open the file \sources\cversion.ini in a text editor and modify the MinClient number to a number lower than the version Windows 7 that you want to upgrade from – so for the beta you would set this to something like 6900.
3. Save the file and then run the install routine from the location with the modified file
