How to upgrade from Windows 7 RC to Windows 7 RTM
Windows 7 RTM was released few days back and most suggested option was to do a clean installation. That’s a good one but then I need to re install all the software and reconfigure everything. To avoid this when I asked few of my fellow friends they pointed me out to this
It is not possible to upgrade from RC to RTM because of the minimum build number Windows 7 RTM settings look for but this can be changed. There is a configuration file called as cversion.ini in which Minimum CLient Version or MinClient can be set to lower value than your current version.
If you try to do it without the change, you will get the error as below.
