How do I set my computer with windows 7 back to factory settings? Also, the thing is my friend that gave it to me has about 450 gb worth of data on it that he wants to save. What is the best way to save his data so I can set the computer and windows 7 software back to factory settings? I thought about storing it online somehow...? I don't have any money and don't plan on spending any. He does have a new computer with more memory, but he wont transfer the data to his computer due to lack of data transfer connection hardware. Is there a way I can transfer the data from my computer to his computer wirelessly? Thank you.
