With Windows XP, Microsoft hoped to have one codebase that would span everything from consumers to corporate desktops. Microsoft was fairly ambitious with XP. There was an embedded version that went everywhere, from phones to information kiosks. Banks in particular embraced it as a way to migrate off IBM's dead-end-but-once-great OS/2. Consumers have been quicker to ditch XP for Windows 7 while businesses hem and haw and slowly test a decade's-worth of custom apps on Windows 7. Some estimates show that XP still has a hold on 48% of the Windows market."
