winnate: upgrading a windows 8.1 preview version to rtm

you might have missed the news, but windows 8.1 and server 2012 r2 rtm versions are available for download now. in celebration of this occasion, i draw upon your memory. remember this FULLY UNSUPPORTED little gem when you upgraded your beta version of windows 8 to rtm? uh huh. yes, you do. use at your own risk. feeling like living dangerously?

here’s how it’s done:

  1. expand the installation media or copy to a writeable location
  2. open the directory “sources”
  3. locate the file named “cversion.ini”
  4. modify the content, changing the values to:
[HostBuild]
MinClient=9431.0
MinServer=9431.0

now away you go. when you install, it’ll treat it as if you’re installing over windows 8, not windows 8.1 preview. :)
