I have been flabbergasted this week at all the reaction to the non-news that Microsoft will allow business customers to buy a PC with Windows 7 installed and then replace its OS with an earlier version (specifically, Windows Vista or Windows XP). The common thread in all the blog posts and comments I’ve seen is that this represents Microsoft “planning to fail” with Windows 7.
Uh, no.
For starters, this is not new. I’ve clipped the relevant portions from various Windows license agreements through the years and posted them at ZDNet: There’s nothing new about Windows downgrade rights. Anyone who gets all breathless about this policy doesn’t understand Microsoft’s business model and is clueless about corporate computing. So let me see if I can explain here.
When you buy a new PC with Windows preinstalled, you are actually buying a Windows license along with that hardware. The Certificate of Authenticity on the side of the PC is the physical evidence of the license, which is embodied in a detailed agreement. The terms of the Windows license vary, depending on which edition of Windows is installed.
Home customers buy a license to run a specific version of Windows, typically Home Premium. If you want to replace that installed OS, you have to buy a new license.
Business customers buy a license to run Business or Ultimate edition (depending on which one they paid for). But the terms of that license include a section that is not part of the home license. These business licenses include downgrade rights. In the case of Windows Vista Business edition, this section specifically allows you to replace, Vista Business with XP Professional. You as a corporate IT professional might want to do that while you plan migration of all the PCs in your business. Your existing systems are running XP, and you want the new PCs to fit into your existing infrastructure. When you’re ready to upgrade, the license allows you to restore Vista Business.
As I said, this is nothing new. If you bought a PC with Windows XP Professional anytime in the past eight years, it contained a similar clause in the license agreement allowing you to replace the installed OS with Windows 2000 Professional, Windows NT Workstation version 4.0, or even Windows 98 Second Edition. Back in 2001 or 2002, those operating systems were in wide use, and people might not have been ready for the headache of upgrading to XP.
Anyway, that’s what all this means. Nothing more, nothing less. When Windows 7 comes out, customers who buy a business license will have the right to maintain compatibility by choosing older business versions of Windows without violating the terms of the license.
Sorry, conspiracy theorists.
Update: Just a note to clarify this isn’t aimed at my ZDNet colleague Mary Jo Foley, who stopped by the comments section with a link to her excellent post on the subject: Microsoft will allow Windows 7 users to downgrade to XP. An awful lot of people have been piggybacking on her original reporting and adding their own miguided interpretations.
