I find this infuriating, but today I started my computer only to get a "genuine windows product" check dialog. Owning a 100% genuine Windows 7 Home edition, I clicked "check online". This brought me to a Microsoft support webpage that claims that my copy was "not purchased" and "not genuine" then proceeded to "remove or disable essential features until purchase of a valid license".
Angry, I went to Microsoft Support, entered my CD-Key and then it claimed that it too was not genuine and I had to pay 59.99 just to access support and get the issue resolved.
I paid 150$ for a product that doesn't work. Now I need to reinstall Windows and use an activator, have any of you had this issue or any similar stories?
