How to bypass the restrictions Windows 7 RC upgrade directly to RTM

Although Microsoft officially claims that Windows RTM does not support direct upgrade installation from the RC version, when users run the RTM installer directly on the RC version, they will find that the upgrade installation option is not available, only the custom installation method can be used. The original system files will be moved to a Windows.old folder. But in fact, this is just a "scared" argument, because the method of cracking the restriction already exists, and Microsoft has been ignoring the existence of this method, it seems to acquiescence to this modification.

Someone may have thought of it, yes, just like the way to upgrade from Beta to RC, modify the cversion.ini file in the installation image. Many people have successfully upgraded to Windows 7 RTM using this method. The specific method is as follows:

Unpack the downloaded ISO image file;

Go to the "sources& rdquo; directory; Br>

Open the “cversion.ini” file with any text editor;

Change the 7233.0 in the second line <;MinClient=7233.0” to the version number 7100.0 of the RC, save and close Editor;

But here is a reminder to everyone, although this method can be used to upgrade Windows 7 RTM directly on the basis of the RC version, but there may be some uncertainties that lead to some unexpected situations in the future use, so Do not encourage everyone to upgrade the installation directly, presumably this is the original intention of Microsoft to make restrictions.
