With the release of Windows 10, Microsoft has quietly made changes in the activation of retail upgrades of Windows, including free upgrades to Windows 10, which will be available for one year since the release of the operating system (29 July 2015). The end result is that now perform “clean” installation of the system will be much easier, however, only after the passage of the “baptism of fire” (the first installation).
To OEM-versions of Windows 10 activation procedure has not changed, as, indeed, and for copies of “tens” distributed under the terms of the License Agreement Volume Licensing. However, large-scale campaign for the dissemination of the Windows Update 10 suggests that these variants retail updates will be very important, at least in the near future.
Perhaps the most significant change is that the activation status of devices on Windows 10 is now stored in the “cloud.” Thus, after the first successful activation, users no longer need to enter product key every time you reinstall system. This is a big change compared to previous versions of Windows, where required to enter a product key every time you perform a “clean” installation. The only exception is for laptops with pre-installed Windows 8.1, and support for UEFI Secure Boot. It can also become an unpleasant surprise for those who will attempt to perform a “clean” installation of Windows 10, not knowing all the details of the new mechanism of activation.
For a long time, Microsoft’s activation server using a unique identifier based on the hash of the user equipment. In other words, the mechanism of activation involves the identification device, not its owner. In previous versions of Windows, when the first activation of the hash value (ID setting) is recorded in the database activation, in addition to the need to enter the code every time you install the product. And when users reinstall the same copy of Windows on the old equipment, activation occurs automatically.
Now, when you upgrade to Windows 10, Windows Setup 10 checks the status of Windows Activation and reports the result of activation servers. The server then generates a Windows Activation license certificate, which is stored in one with heshom equipment and Windows file 10 Home or Pro. Thus, such a thing as the Windows product key is practically a thing of the past (for authentication to use Windows utility Software Licensing Manager).
Of course, Microsoft is not willing to be distributed over the parts of the activation process. However, this is not surprising, because every, even insignificant, detail concerning anti-piracy measures corporations could be used by attackers to bypass security mechanisms.
However, a little disappointing that customers Microsoft, which uses Windows, is necessary at all to think about how to activate. PCs running Windows, for which the consumer paid the money, and spent his time on the installation of the update should just work.
