Can I install Office Home and Student 2010 on more than one device?
It depends on what you purchase—a Traditional Disc or Product Key Card. If you purchase a Traditional Disc retail license of Office Home and Student 2010, the retail license terms allows you to install, activate, and use Office Home and Student 2010 on up to three PCs in a single household. If you purchase the Office Home and Student 2010 Product Key Card, you can only activate and use Home and Student on one PC or device.
