I installed the Office 2010 Home And Student 64bit when I purchased the disk from my school. Well the computer got fixed and the company that fixed it drained all my important things that I had on the computer. They said I Microsoft Office 2007 Ultimate Activation needed to Microsoft Office Enterprise 2007 Activation micro Office Professional 2010 Product Key student Windows 7 Enterprise Product Key and now I cannot Windows 7 Starter Activation Key my disk. Is it Genuine Windows 7 to find the product key some where on your computer, call the company? or do I have to purchase another disk?
