It looks like you can upgrade to Windows XP Professional x64 Edition, but there are a bunch of little limitations and compatibility issues you might have with it. Since you're going to have to buy a new Windows License anyway, you might as well upgrade to Vista or Windows 7. Windows XP almost 10 years old, and nearing the end of its life. According to a couple websites selling the Lenovo G560, it ships with Windows 7 64-bit these days, so there should be no compatibility problems. | |||||
