Windows 10: Upgraded PC but Windows 10 won't activate

After upgrading my PC, I go to the Windows activation app, click "troubleshoot", then click "I changed my hardware on this device recently".


After selecting my device and clicking activate I always get back "We can’t reactivate Windows on this device. Try again later."


I have tried many times over a few days and it never works.


How can I activate Windows?

If you upgraded to Windows 10 for free and ended up in a non-activated state, try following these steps:

• Go to Start
  
  , then select Settings > Update & security > Activation.
• Select Go to Store, and check to see if a valid license is available for your device. If a license isn't available, you'll need to buy Windows from the Store.
  
  Note
  • This only applies if you haven't made changes to the hardware for your device.

or you could hack it with a crack but please note this is always risky and you don't know what's in the hack
