What are some of the common causes of WGA validation failure?
Often, users have no idea that their copy of Windows is counterfeit. The most common cause is the “repair shop” scenario. In this scenario, a genuine Windows customer takes their PC to be repaired. Unbeknownst to the customer, the repair shop installs an unlicensed copy of Windows. The customer has a genuine product key, but a non-genuine key was used to install the system. Another common scenario is someone purchases a new PC from a dishonest business that charges them for genuine software but installs a pirated copy of Windows. The user knows they have paid for a copy of Windows, but they are actually running pirated software. Microsoft provides assistance, including in some cases, a free replacement copy, for customers who experience these issues.
