how many computers can you install the windows7 product key on how many computers?

You are allowed to install Windows 7 on one computer or laptop.
Two computers or laptops require you to purchase another license from Microsoft, and so on. One license per computer/laptop.

Unless you have purchased the Windows 7 Family Pack or have a Volume License agreement then you can only install one copy per computer per COA/(License Key)
