Query: Don't waste your money on Microsoft.

DO NOT SPEND YOUR MONEY ON THIS PRODUCT. Registering and using this product makes you vulnerable to identify theft and retail fraud. These are serious crimes and extremely difficult and time consuming to resolve. I had been a long time customer of Microsoft, and their customer support did nothing to resolve my problems. Save yourself the headache and don't buy this product. Similar services are available for free with other companies, and you won't need to provide your personal data & billing information.
