Understanding activation and registration
There are important distinctions between activating your Windows operating system and registering it.
Product activation and product registration are not the same. Activation is completely anonymous; it requires absolutely no personally identifiable information to complete. Activation is required and ensures that each Windows product is not installed on more than the limited number (usually one) of computers allowed in the software's end user license agreement, or EULA.
During activation, you can also register your copy of Windows. Registration is not required; however registering your copy ensures that you receive product support, product update information, and other benefits. The process registration takes only a few minutes to complete. Personal information (for example, "contact" information such as an e-mail address) is required if you decide to register.
You have a short grace period in which to activate your Windows product installation. If the grace period expires and you have not completed activation, login will be incomplete until you activate.
