How to Upgrade Windows 7 Beta or RC (Prerelease Version) to a new Windows 7?07.12.13

Anonymous

1. Copy or download the Windows 7 RTM ISO to the computer that wants to perform the upgrade.
   2. Mount the ISO image onto a virtual DVD drive and copy the whole content of the image to folder which can be located anywhere (on any partition or drive on the machine running the pre-release build, or external hard disk or USB/FireWire flash drive connected to the computer).

Alternatively, itâ€™s possible to directly extract the content of the ISO to a desired folder using file extraction tool such as WinRAR.
   3. Browse to the sources directory.
   4. Open the file cversion.ini in a text editor such as Notepad.
   5. Modify the MinClient build number to a value lower than the down-level build. For example, change 7233 to 7000.

Original content of cversion.ini:
      [HostBuild]
      MinClient=7233.0
      MinServer=7100.0

Change it to:
      [HostBuild]
      MinClient=7000.0
      MinServer=7100.0
   6. Save the file in original place and original name.
   7. Double click on setup.exe from modified installation files to start Windows 7 installation, and choose Upgrade to in-place upgrade to latest RTM gold build of Windows 7. The version check will be skipped and bypassed.
