Microsoft, has released the beta version of its most awaited OS i.e Windows 7. If you haven’t downloaded the beta version of windows 7 then you can download it. To activate the beta version of Windows 7 you need to have legit Windows 7 beta serial key. You can get windows 7 key, you can registered it from Microsoft Site. Because of the overloaded Microsoft servers it can be hard to get a valid key. To get a valid key then use the following links:
