Windows 7 Will Not Inherent the Incompatibility Issues of Vista

Microsoft is hard at work aiming to prevent the Windows 7 apple proverbially falling close to the Windows Vista tree. In fact, Bill Veghte, Senior Vice President, Online Services & Windows Business Group, promised that that incompatibility issues would not be among the legacy that Vista leaves for Windows 7. Otherwise, the next version of the Windows client will inherent the vast majority of the architecture of its predecessor, most importantly the core of Vista. But, in addition to the kernel, Windows 7 will also feature the same graphics and audio subsystems

as Windows Vista, context in which existing hardware and software products will continue to be compatible.
"You've let us know you don't want to face the kinds of incompatibility challenges with the next version of Windows you might have experienced early with Windows Vista. As a result, our approach with Windows 7 is to build off the same core architecture as Windows Vista so the investments you and our partners have made in Windows Vista will continue to pay off with Windows 7. Our goal is to ensure the migration process from Windows Vista to Windows 7 is straightforward," Veghte stated.
This is, in fact, Microsoft's vision: Windows Vista will be a transition operating system, streamlining the migration to Windows 7. Officially planned for availability within three years since Vista hit the shelves on January 30, 2007, Windows 7 is heading for a more realistic launch date at the end of 2009, but ahead of the holiday season.
