Will it be possible to upgrade from Windows 8 Release Preview to the RTM version?

I've seen this related question Upgrade/Update Windows 8 customer preview to normal version, but I'm interested to know if I will be able to upgrade from the Release Preview to the final Release To Manufacture version.

Best Answer

  • Microsoft had already announced that there would be no upgrade path from the Release Preview to the RTM version of Windows 8, and for whatever reason you'd still want to be able to do this, it appears it's now possible with an easy (unsupported) workaround.

  • A blogger over on the Knowledge Exchange posted the details on how to fool the RTM to allow the upgrading of the Release Preview and earlier versions of Windows 8 as far back as the Developer Preview. This trick should work on any version of a test Windows 8 build anyway.

  • Simply find the n:\sources\cversion.ini file on the media and open it with notepad. Change the two numbers from 8508 to 7100 save and close the file.

  • You need to put your extracted ISO / installation in a place you can make changes to it to edit this file. In short, in a writable disk.
