How To Upgrade Windows 7 RC to Windows 7 Final(RTM)

I’m one of the thousands of happy Windows 7 RC early adopters and it’s time for me to upgrade to Windows 7 Final version as Windows 7 RC is all set to expire on February 15, 2010. I had a free ride of Windows 7 all these days and today shelled out few bucks to get the best ever Windows operating system released by Microsoft.

I’m using Windows 7 RC for several months and it has all the required software and configurations. So I want to just upgrade RC to Final version without loosing anything and chose the upgrade option. The installer popped an error saying i can’t perform the upgrade.


What? I cant’ perform an upgrade is it? Oh that’s bad. This is not something I like or any other user as it’s very pain full to reinstall and configure all the required software on a fresh OS copy. But luckily a quick search revealed very easy trick that allowed me to upgrade Windows 7 RC to Windows 7 Final (RTM).


Here are the steps to be followed

  1. Copy the Windows 7 DVD files to your hard disk( if you are using an ISO image file, extract it with the help of unzip tools like 7 Zip)
  2. Navigate to Source folder from the copied/unzipped installer files and open cversion.ini file using notepad application
  3. Change the MinClient value to 7000.00 as shown in the following image and save it











That’s all. Now you can re-launch the setup.exe file to upgrade Windows 7 RC to Windows 7 Final. That’s easy right? Yeah. I feel good of saying ‘I’m a PC’.
