Activating Windows 10 after the free upgrade from Windows 7 or Windows 8.1
If you upgraded to Windows 10 for free from an eligible device running a genuine copy of Windows 7 or Windows 8.1, Windows 10 will automatically be activated online and create a digital entitlement for your device.

To check activation status for your current version of Windows:
- In Windows 7, select the Start button, right-click Computer, and then select Properties. Your activation status is under Windows activation.
- In Windows 8.1, go to Control Panel, then select System and Security > System. Your activation status is under Windows activation.
After you complete the free upgrade to Windows 10, it will be automatically activated online. To check activation status in Windows 10, select the Start
button, then select Settings > Update & security > Activation. If Windows 10 isnít activated on your device, see Get help with Windows 10 activation errors
for more info.
