In addition, you can use Windows 7,windows 8 or Windows 8.1 Product keys to activate installation of Windows 10, starting with the November 2015 update to Windows 10, which is version 1511. Also, to further complicate, Microsoft has provided Windows 10 with a default product key that can be used to unlock the version without activating it. I have seen an article from a notorious sensational, always inaccurate source, claiming that this allows Windows Pro’s “free Upgrade”.
However, the new rules do enable some interesting scenarios, especially in the case of version upgrades, such as turning from Windows home to Pro. In particular, this means that you may be lying there with the old product key suddenly worthwhile. Microsoft, for example, has slashed prices to upgrade Windows 8 Pro in the first few months of its release. In addition, you may also have available Windows 7 Professional or Ultimate retail versions, where the licenses associated with their product keys are no longer in use. These keys can be reused, and you can save 100 of dollars by upgrading from Windows Home to Windows Pro. I recently tested the upgrade/activation scheme on a variety of hardware to see how things work.
Scenario 1: Cleaning up the reinstallation
I recently upgraded SSDs with the HP Spectre X360 originally provided with Windows 8.1 home, and then upgraded to Windows Pro. After the upgrade is complete, I use a USB flash drive to reinstall a clean copy of Windows? Pro. During the installation process, you are prompted to enter the product key two times. Twice I chose to skip the option to enter the key.
After the installation is complete, I log in and check the activation status (settings, updates and security, activation). The system is properly activated because Microsoft’s servers recognize hardware and use digital rights.
Scenario 2: Clean Reinstall, Version upgrade
As part of my testing, I used a surface 3 that was originally provided with Windows 8.1 Home and has been upgraded to Windows 10 using digital rights. It then upgrades it from the home page to the Professional Edition using the Windows 10 product Key of MSDN. As a result, the device has actually registered two versions of the digital rights of Windows (Home and Pro) on the Microsoft Activation server.
I then downloaded the Microsoft Recovery image for Surface 3, copied it to a USB flash drive, and reinstalled the original operating system, Windows 8.1 home. Next, I use Windows Update to upgrade this system to Windows 10. This works fine, there is a problem: My Windows 10 new installation is for the Home Edition. But I have the digital copyright of Windows Pro. How do I force upgrades? This is where the default product key is. I clicked on the system control Panel to change the product key (there is an identical button on the activation page in the settings). This opens the dialog box.
