Upgrading a copy of Windows 7 RC to a retail copy is much simpler than you could have ever expected. I am sure there are a million and one guides on the internet on how to do this by now. But I thought I would blog my experiences. The process is a painless one but one that will require you to walk away and make a few cups of tea.
Steps:
- Don’t try and ‘upgrade’ straight off the DVD it will not work! you will see this:

- Instead, copy the DVD to a folder on the local hard drive and then edit the file \sources\cversion.ini
- Change the cversion.ini ‘MinClient’ option to a version before or equal to the version on the notice on your desktop stamp.Example if the desktop says
then change the file to
And save the file.
- Launce Setup.exe in the folder the DVD was coped to and select the ‘Upgrade’ option when prompted.
- Follow the on screen instructions and wait.
- Tada!
Hope it works, worked perfectly for me!
