We Can't Activate Windows on This Device

When you reinstall Windows, sometimes you may need to reactivate Windows. However, some people report that Windows displays the message "we can't activate Windows on this device".

I have recently reinstalled Windows... After Windows was reinstalled, I was informed that Windows wasn't activated on my computer... When I troubleshooted, the error I got was "We can't activate Windows on this device right now. You can try activating again later or go to the store to purchase genuine Windows." Along with the error code 0x8007056c. -- answers.microsoft.com
