Product activation is a process of validating your license and you have a legal copy of the software. Activating Windows ensures that you can completely personalize your computer and access all the features and updates offered by Microsoft.
On Windows 11 and 10, if you don’t activate Windows, that may limit your ability to personalize your machine and you may see watermarks and messages prompting you to activate Windows. It should be noted that using an unactivated version of Windows is a violation of Microsoft’s terms of service.
On older versions of Windows, the impact of inactivation may vary. It can limit your personalization options, constantly prompt you for activation, prevent you from receiving Windows updates, or even limit your ability to sign in to the operating system.
