How to upgrade Windows 7 system expires

On February 24th, a friend was very anxious to call to ask why Windows 7 Ultimate installed on his computer popped up: The pre-release version of Windows 7 Ultimate will expire in seven days and require immediate backup of data. . He pointed out that his Windows 7 Ultimate is successfully registered with the activation code he is looking for online. Now he is also confused and can't figure out whether his Windows 7 system is activated.

Originally thought that this problem should be known to everyone, but you can search the Internet and find out a lot of friends who have asked this question. The reason why Windows 7 automatically prompts users that this pre-release version is about to expire is due to Microsoft's policy is limited. Since the beta release, the Windows 7 operating system has been widely watched by users around the world because of its excellent performance. A large number of users are vying to install tests. Before the official release of Windows 7, there were new releases or leaks, so several versions appeared during the test. Some Windows 7 users even found that the system just installed the day before was replaced by the new version in two days. However, as an ordinary netizen, few people take the installation system as a pleasure. The installation system is actually simple, but the backup and restore of important data during the installation process is very troublesome, and the test version is almost a small update, the change is not very obvious, so Most users choose to keep changing and always use this version of their own.

But as Windows 7 continues to upgrade until the official release, there is still a big difference between the original beta and Microsoft, so Microsoft will be able to use the newer version, and gradually test the previous version. Expired, and these betas are so-called pre-release versions. Windows 7 Beta has expired on August 1, 2009. As early as June 17, 2009, users of Windows 7 Beta will receive an expiration notification every day. As the expiration time approaches, users receive notifications.

There are a lot of users who use Windows 7 RC version. After all, it will not be too much difference between the RC version and the official version, but please note that this is still only a pre-release version. The friend who came to ask for help today is also using this version. I found the activation code on the Internet and successfully registered that I can use Windows 7 Ultimate for a long time, but this is not the case. Microsoft is scheduled to notify the Windows 7 RC version of the user system expiration information on February 15, 2010. The notification process is the same as the Beta version:
