The information about enterprise licensing rules on Windows 7 for organizations has been released by a longtime Gartner anaylys, Michael Silver.

According to Silver, “…businesses that buy PCs before April 23, 2010, with Windows 7 pre-installed can downgrade them to Windows XP, then later upgrade them to Windows 7 when they’re ready to migrate their users. But PCs bought on or after April 23 can only be downgraded to Vista.”

Microsoft has not confirmed whether this information is accurate.
