PC makers will offer Windows 7 downgrade rights according to Microsoft.

“We will offer downgrade rights from Windows 7 to Windows XP in the same way we did with Windows Vista,” said a company spokesperson to Channelweb.com. “Volume licensing customers have always had the option of downgrading to a previous version of Windows,” he added.

A blog suggests that Windows 7 Pro PCs can downgrade to XP until April 30, 2010.

“Obviously, Microsoft recognizes that Windows Vista is never going to be accepted as much as they’d like, and realizes that a lot of customers are going to remain on XP until Windows 7 comes out,” said Todd Swank, the vice president of Nor-Tech.
