uninstall winodws 7

If you've been running Windows 7 Beta, Windows 7 RC (release candidate), you may wonder if you can upgrade to the official version of Windows 7.

The official answer is no.

Microsoft has decided that if you are running Windows 7 Beta or RC, you have to start over with a clean installation.

Perhaps this is because they feel that the final version of Windows may have significant differences in the beta or RC version that would make a problematic update. Perhaps its legitimate version of the operating system will begin to close in March 2010 when the betas are set to stop working.

Or perhaps there is no reason at all.

As you might guess, there is an official answer to the question of updating as well. Otherwise there would be no point of writing this article.

The official response is: yes, you can upgrade a beta or RC version of Windows to install the RTM version.

To do this, you have to download the RTM version of Windows 7 ISO, mount the image in a virtual DVD drive, copy it to a local folder, then make some modifications to the file cversion.ini.

There are a few things to think about before considering an upgrade.

First, as mentioned, there could be problems if you upgrade from the RC to the final version of Windows.

In addition, a clean installation is generally preferable to an upgrade.

Yes, it's a pain to set up a new system.

Moreover, when you create a new installation, is more likely to do so in a way that best suits the new operating system.

This does not apply to those going to the final RC for Windows 7, of course, but take this into account if the update of Vista or XP.
