How Long Can You Use Windows 10 Without Activation? (2)

Microsoft launched Windows 10 in 2015 with a one-year free upgrade offer for Win 7 users. But now, you need to pay to activate Windows 10 from the start.

So, some users might assume that they can no longer freely upgrade from previous Windows platforms to Windows 10.

However, users can freely download the Windows 10 disc image (ISO) file from Microsoft’s website with the media creation utility. Users can upgrade to Win 10 with that file.

During the Win 10 installation, users will be asked to enter a product key. Then they can click I don’t have a product key to install the OS without a product key.

Users will have then upgraded to an unactivated Windows 10. The unactivated version comes with some relatively minor restrictions. For example, users can’t change desktop wallpapers or themes within the unactivated Windows 10; and some of the platform’s apps will not work.

Most users have no idea that they can still upgrade to Windows 10 free of charge. Learn how to do that from this excellent guide.

Thereafter, users will see some Activate Windows now notifications. Windows will send out regular notifications requesting that users activate an unactivated Windows 10.

Furthermore, the Activation tab in Settings will include a notification requesting that users activate the OS with a product key. Their users can click Change product key to activate Windows 10 or change the product key with another one.

However, users can leave Windows 10 unactivated. In fact, users can continue to utilize the unactivated Win 10 with the few restrictions it has. Thus, Windows 10 can run indefinitely without activation.

So, users can utilize the unactivated platform for as long as they wish. Note, however, that Microsoft’s retail agreement only authorizes users to utilize Windows 10 with a valid product key.

What happens if you don’t activate Windows 10 after 30 days?

Windows 10 has a trial period of 30 days for which you can use the OS without a product key. During this period, you will have access to all its features and get a feel of what you will get in the full package.

After that trial period, you will still be able to use Windows 10 but now with restrictions. Some features and customizations will not be available to you until you activate the OS.
