Windows 10: Expiring date after upgrading to Windows 10

Good catch, I didn't see that until his post number 12.

 

So, the question now is, where have you been downloading your Windows 10 from? Basically you have an activation that is typically used to pirate Windows with. You sometimes get those pirated versions of Windows by downloading them from sources other than Microsoft. The next question is, do you have a legitimate Windows 7, 8, 8.1 or 10 product key that you can manually enter to activate Windows 10 Pro with? Here a few things to try.

First,
Select the Start button, then select Settings > Update & security > Activation.
Select Change product key, and then enter this 25-character default product key:
VK7JG-NPHTM-C97JM-9MPGT-3V66T

What happened? Did it accept the product key and activate? Did it accept the product key and not activate? (The above is straight off of Microsoft's website)

If the generic Windows 10 Pro product key is not accepted above then try RIGHT clicking on start icon, select command prompt (admin), and run the following:

slmgr /upk
slmgr /ipk VK7JG-NPHTM-C97JM-9MPGT-3V66T
slmgr /ato

If that didn't work, then change the product key to a legitimate Windows 7, 8, 8.1, or 10 Pro product key.

Try both methods above, but use the Windows 7, 8, 8.1 or 10 Pro product key instead of the generic Windows 10 product key.

Good luck!

 

Before the upgrade I was on a Windows 10 Insider Build Preview 10547 (it wasn't downloaded from the Microsoft site) running with KMSpico activator. And no, unfortunately I don't have a legitimate Windows key.

So I do what you told me (I'm gonna post the results as pictures):

KMSpico activator is an illegal method of activating Windows 10. We can't help you any more here until you purchase a legitimate Windows product key.
