Hi all . I just have a small question: Can Technet keys be used after subscriptions expired? I mean that, those keys have not been used. While my subscriptions is still active, I get all the keys I can and save them into a text file (just save, not use). If my subscriptions expire, can I use those keys to activate new installations of Microsoft products (Windows, Office...)? Sorry if it's difficult for you to understand. I'm not so good at English Thanks in advance.
