The Windows 7 juggernaut has little regard for impediments, but it does have a soft spot for an elderly cognate that refuses to die: Windows XP. Microsoft marked the availability of the public beta for Windows 7 Service Pack 1 (SP1) by extending the end-user downgrade rights to Windows XP until 2020, even though the previous deadline for their expiry was set at Windows 7 SP1.
End-user downgrade rights let businesses use a prior version of Windows on new machines until they are ready to transition to the latest version. Only OEM copies of Windows 7 Professional and Ultimate include downgrade rights to Windows XP or Windows Vista Professional. According to Microsoft, the move is meant to “provide customers and partners with more predictability around the lifecycle of Windows.”
Apparently, its business customers feared that removing end-user rights could lead to confusion. “Going forward, businesses can continue to purchase new PCs and utilize end user downgrade rights to Windows XP or Windows Vista until they are ready to use Windows 7. Enabling such rights throughout the Windows 7 lifecycle will make it easier for customers as they plan deployments to Windows 7,” Microsoft's Brandon LeBlanc wrote in a blog post yesterday.
