Win10 build 10565 preview version can be activated using Win7/Win8.1 key

The Win10 activation mechanism is very loose compared to the previous XP, Vista, Win7, Win8/Win8.1, because Windows 7/Windows 8.1 users can upgrade for free. Of course, at present, this "loose" has a deadline: one year after the official release of Windows10. For users who have not upgraded and installed Win10, in order to use it for free, they must go through the process of upgrading and installing.

But for users who have installed the system, the upgrade system is generally not as good as the full installation, because it is difficult to avoid compatibility issues, so many users are formatted immediately after the upgrade. Install it again. Although this installation saves the capital consumption of the system, it has to be said that it takes a lot of time and effort. In order to use Win10, it has to be installed twice. Now Microsoft has taken greater sincerity and removed the toss of Win7/Win8.1 users. If you want to install Win10 Preview 10565 and later directly, you don't have to use the upgrade method. You can activate your existing Win7 and Win8/Win8.1 keys after installation. The interface to enter the product key is still the old place: set → update and security → activate, then select “change product key & rdquo;. Or you can enter it directly during the installation process.

Microsoft has become more and more aware of the issue of Win10 activation. Since you want all eligible users to upgrade to Win10 as soon as possible, it is necessary to minimize all kinds of "blocking the tiger". Three years to install 1 billion devices is Microsoft's expectation for Win10. According to Microsoft's statistics, after more than two months of Win10 release, this goal has been completed by more than one-tenth. Microsoft said that the current global Win10 equipment has reached 110 million units. . This speed has exceeded the historical level of Win7, but if you do not continue to refuel, it may be "reverse the boat", after all, this phase of "blowout" is related to the enthusiasm of fans. Therefore, in addition to good news for users, these convenience measures are also good for Microsoft itself.
