Windows XP users will be able to upgrade to Windows 7 without paying the full price. However, XP users will have to perform a clean install of Windows 7. Finally, Microsoft is heavily suggesting that Windows 7 will be capable of running on netbooks, which are smaller notebooks that typically use lower cost hardware components. Currently, netbook vendors sell them running a version of the Linux operating system or Windows XP. With Windows 7, Microsoft is on track to have a smaller OS footprint with faster boot-up and shut-down times, and improved power management.
