The steps provided are a workaround to upgrade from the Windows 7 Release Candidate (RC) or Beta versions to the Release to Manufacturing (RTM) version of Windows 7. Here's a breakdown of the process outlined in the instructions:

1. Mount Windows 7 RTM Build 7600 ISO:
   • Obtain the Windows 7 RTM Build 7600 ISO and extract its content to a folder or a USB drive.
   []Modify the "cversion.ini" file:
   • Navigate to the "Sources" folder of Windows 7 within the extracted RTM content.
   • Locate and open the "cversion.ini" file using Notepad.
   []Adjust the "MinClient" build number:
   • In the "cversion.ini" file, find the "[HostBuild]" section.
   • Modify the "MinClient" build number to a value that is lower than the build number of the installed Windows 7 version.
   • For example, change "MinClient=7000.0" if you have Windows 7 Beta Build installed, setting it to a lower version like "MinClient=7000.0".
   []Save changes and run setup.exe:
   • Save the updated "cversion.ini" file in the same location.
   • Run the "setup.exe" executable from the extracted RTM content to initiate the Windows 7 RC upgrade process.
   []Follow on-screen instructions:
   • Proceed with the upgrade process, following the on-screen instructions that appear during the upgrade.
   • Choose the "Upgrade" option when prompted.

     Note:​

     • Although this method can work for some users, it's important to proceed with caution as modifying system files like "cversion.ini" can potentially lead to system instability or unexpected behavior.
     • Creating a backup of important data before attempting such a modification is highly recommended in case any issues arise during the upgrade process.
