To activate Windows 10, you need to open the ‘Command Prompt’ and for that, first, you need to press the ‘Win +R’ key shortcut.
Doing so, will open the ‘Windows Run Dialog Box’ and in that type ‘CMD.’
Then, hit the ‘Enter’ button to finally open the ‘Windows Command Prompt.’
After that, press ‘Ctril+Shift+Enter’ key together and click right on the same to run the ‘Command Prompt’ as ‘Administrator.’
Now, in the command line, paste the ‘slmgr.vbs /upk’ code and press the ‘Enter’ button.
Again, paste ‘slmgr /ipk NPPR9-FWDCX-D2C8J-H872K-2YT43’ code in the command line and press the ‘Enter’ button in order to execute the command to install the Windows 10 activation key.
One more time, paste these following codes ‘slmgr /skms zh.us.to’ and ‘slmgr /ato’ to finally activate the Windows 10 for free.
That’s it! This is how you can successfully activate Windows 10 and if you want you can also activate Windows 10 Pro for free in the same way.
