When you facing problem for activate windows 10 on your PC or laptop after upgrade from windows 7, windows 8 there are several reason. Here are some reason and solution you can try to fix the problem:

You upgraded to Windows 10 for free from Windows 7 Service Pack 1 or Windows 8.1 Update

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

  1. Go to Start Start button icon, then select Settings > Update & security > Activation.
  2. If your activation state says Connect to the Internet to activate Windows, it might mean you’re not connected to the Internet or the activation servers are busy.

    If you’re connected to the Internet, Windows 10 will be automatically activated. You can also select Activate to try and manually activate Windows. If the activation servers are busy, you might need to wait a while and then try again later.

  3. If your activation state says Windows is not activated, select Go to Store, and check to see if a valid license for Windows is available for your device.

    If a license isn’t available, you’ll need to buy Windows from the Store or go back to your previous version of Windows, make sure the previous version is activated, and then upgrade to Windows 10.

You upgraded to Windows 10, but didn’t have a previous version or the correct edition of Windows installed (error 0xC004F061)

If you see error 0xC004F061 when you try to activate Windows 10, it means one of the following:

  • You’re using a product key to upgrade to Windows 10, but a previous version of Windows wasn’t installed on your PC. To update, you need to have Windows 8 or Windows 7 already on your PC.

    If you formatted or replaced your hard drive, you won’t be able to use a product key to update to Windows 10. You’ll need to install your previous version of Windows, and then reinstall Windows 10.

A different version of Windows or the product key might have been used as part of a repair

If you took your PC to a repair shop or to someone who builds and fixes PCs, it’s possible that a different version of Windows was installed to complete a repair. Or, if a different product key was used for your PC during the repair, that key might be blocked if it was used on more PCs than the Microsoft Software License Terms allow.

If Windows was activated before your PC was repaired or rebuilt, then re-entering the product key that came with your PC or original copy of Windows might solve the problem. You can also try reinstalling your original version of Windows.

One copy of Windows might have been installed on multiple PCs (error 0xC004C008)

If you have one copy of Windows and installed it on more than one PC, activation might not work because the product key has already been used on another PC, or it’s being used on more PCs than the Microsoft Software License Terms allow.

If your product key is being used on more PCs than the Microsoft Software License Terms allow, you’ll need to buy a new product key or copy of Windows for each of your PCs in order to activate them.
