Windows 10: windows 25 digit activation code.

I purchase new laptop with Windows 8 pre installed with it. Windows 8 later on upgraded to windows 10 after some time. No paper came with it that includes the Windows Product Key (25 digit) for activation. Now computer recently was reformatted dut t some problem. Now Computer is sometimes asking for 25 digit activation code, but how do I find this key/code within my computer in case I need it now for using. Pl. let me know how to find it.

Windows 10 will not activate Error code 0x803F7001


Possibly there can be the problem with Microsoft activation Server, so your Windows 10 is not activated. In this scenario, you need to wait and verify if it is the issue from Microsoft’s side. But if you are getting error code 0x803f7001, you can also try these steps:

1. Open Settings app. Then go to Update and security > Activation screen > Change product.
2. Type your Windows edition product key and click Next.
3. You’ll get We couldn’t activate Windows error message.
4. Retry steps 1-3 then type your 25-characters unique product key.
5. Wait for the process to complete, Windows 10 is activated.

Hope something helps this problem

How do I get a 7 digit code to reinstall windows 10

If you previously had Windows 10 installed and activated on that PC
during the installation process skip the steps which ask for a product key and select the option 'I am Reinstalling Windows 10 on this PC', and activation will not be an issue, your PC will have a digital entitlement stored on the
Microsoft Servers

The 7 digit code is used to confirm your ID with your Microsoft account

Please follow these steps:

• Open the Settings App, go to Accounts
• You should see the "Verify" link just above your picture
• Check your Email to see if Microsoft have sent you a 7 digit code
• Enter the 7 digit code when asked
