When you perform a clean install of Windows 10 from USB, ISO or DVD without entering a valid product key, Windows 10 is installed in trial mode, and is valid for 30-days only. The user has to either activate the install using a valid product key to continue using without any limitations or remove the installation after the trial period is expired.
Once you start using the trial copy of Windows 10, Windows will display automatic activation popups at regular intervals asking you to enter the product key to activate the installation even during the trial period. As said before, the automatic activation messages start to appear in the first 30-day trial period itself and doesn’t start after the trial period.
This is because, like previous Windows versions, Windows 10 also comes with automatic activation feature, and this automatic activation is responsible for the frequent activation popups that appear during the trial period.
Although the automatic activation feature is useful and does nothing but simply reminds the user to activate the copy of Windows 10, not all users like this frequent activate Windows popup messages.
If you don’t want see the automatic activation popups every now and then, you can turn off or disable automatic activation feature in Windows 10 by making a small change to the Registry.
