Greetings. Now that Technet and MSDN subscribers have access to legit keys, I want to pose a question and see if anyone can help me out. I purchased an upgrade license (can't believe I have to wait till October 22nd, argh) for Windows 7 When the 50% off promotion was going on. Basically what I want to know is this: Can I do a clean install of Windows 7 *now*, and just rearm until I get my upgrade license on Oct 22nd, then input my key, and be legit? I can't find any reliable information on rather I can do this or not. I do have a valid Windows Vista key and a Vista DVD. But I don't know if the upgrade license will ask me to present one or both of these, or neither. I assume the keys going out today are full license keys, but if anyone can shed some light on this, It would help me out!
