How to uninstall and deactivate Windows 7 from a computer?
 

I am not that computer Microsoft Office Home And Student, so I do not know much. I was just Microsoft Office 2010 Home And Student Key what Windows 7 is and how it is better than Office 2010 Home And Student 32bit. I managed to download a tool from Office Professional 2010 64 Bit and it said that my computer was compatible for Windows 7. Now, how do I go about getting Microsoft Office Home And Student? Is it free to download or do I have to buy it? If so, how much does it cost?
