Win10 official version of the hard drive can also be activated?

Windows 10 uses a different activation and secret key storage method than before, especially from Windows 7, 8.1, Microsoft activates the server to identify and remember your device status, and saves the activation key on the server. Therefore, how to reload will automatically activate, quite intimate. However, remembering the status of the device also means that your computer can't change the configuration at will, so many users are confused. I changed the hard disk and reinstalled it. Can it be activated?
Gabriel Aul answered the question from the netizen today. If your Windows 10 is active on your old hard drive, you can replace the hard drive, reinstall the system, and reactivate it. Of course, the last step is Microsoft's help for you.

Some users also said that Windows 10 can no longer be activated after doing this. This is probably because Microsoft activated the server temporarily busy, please wait a few days.
Note! If your entire platform is upgraded or replaced, it won't be activated automatically.
