Windows 10: Windows wont activate itself

I recently changed hardware on my pc. At first it was okay and showed me that windows was activated. But a few days later the watermark appeared on the screen. I tried troubleshooting it, picked i changed hardware recently. It takes me to the other window. i pick my current setup. Press activate windows, and it just gives me an error, and does not activate it.

Hi,

Thank you for contacting Microsoft Community. Your interest in Windows 10 is much appreciated.

“Due to high demand for Windows 10 globally, few of us may experience a temporary delay in activation. For Activation Errors
“0xC004C003 or 0Xc004F050” request you to wait for 24 hours and Windows 10 should activate automatically without any issue on your machine.”

As a work around I suggest you follow the below steps to activate a couple of activation issues.

• 
  Push the start button
  
• 
  Type Settings
  
• 
  Navigate to Update and Security
  
• 
  Click on Activation

Have you tried the second step?

(Searching for the error message e.g.

is also a useful approach- e.g. finds

- where the next step is the one I suggested above).
