OEMs have been given an additional six months to sell PCs running Windows Vista with the ability to downgrade to Windows XP using an accompanying recovery disc. Partners originally had up until January 31 2009 to provide the Windows XP Professional recovery media with machines running Windows Vista Business or Windows Vista Ultimate. Now they have until July 31, 2009, a Reg reader has informed us.

You can find information on the original deadlines here, here, here and here (warning PDF).
