Microsoft will ship Windows 7 sometime in or near Jan. 2010, according to a letter company senior vice president Bill Veghte sent to Microsoft customers Tuesday.
The letter, sent to enterprise and business customers, will eventually be publicly posted on Microsoft's Web site.
In the letter sent to "Windows Customers" and titled "An Update on the Windows Roadmap," Veghte said "our plan is to deliver Windows 7 approximately three years after the January 2007 general availability launch date of Windows Vista."
Veghte wrote, "You have told us you want a more regular, predictable Windows release schedule" and he said that was the impetus for setting the 2010 ship date.
Vista has been slowly gaining steam, but is still drawing fire from critics who say it has not lived up to promises.
Veghte went further in addressing customer concerns over application compatibility, which had been a problem shortly after Vista's release.
"You've also 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's discussion of Windows 7 was part of an effort to clarify the June 30 XP deadline that will see the operating system removed from retail shelves and OEM hardware, and to tout the virtues of Windows Vista. Veghte also thanked customers for their loyalty and support.
