Summary
Product Activation was first introduced into the Windows family with the release of Windows XP in 2001. Activation pairs your product key with your computer. It is also used as a mechanism for copy protection in addition to defining support rights depending on the product channel from which the software was acquired: Retail, OEM, Volume License, Trial. With Windows 10, Microsoft has made huge announcements regarding product distribution. The most notable being that Windows 10 will be free to existing Windows 7, 8/8.1 users for the first year. Regardless of this, product activation remains a part of Windows 10 in current previews. It remains to be seen if the final release will include the technology. In this article, we take a look at product activation and troubleshooting steps.
