Users need to enter product keys to show that they have obtained their software packages legally. When valid keys are entered, users have effectively activated the products.

Windows 10 is one of the biggest software packages in the world (alongside Android 10 and 11) in terms of its user base. More than one billion devices now include Windows 10 on them.
