You probably knew that a lot of dissatisfied WIndows Vista users had downgraded — some might say “upgraded” — to Windows XP. It was never clear exactly how many people took that step, but it was enough that Microsoft extended the shelf life for XP for a while. Now we have a number, thanks to a survey by Devil Mountain Software: nearly 35% of new Vista machines are being downgraded.

The survey used data from PCs that have been shipped in the last 6 months, and included machines that were downgraded by vendors before delivery or by users after the fact. The Register seems to think that Microsoft is shifting focus away from Vista, and instead increasing the marketing effort for its next major OS release, Windows 7. I hardly think these numbers spell doom for Microsoft, but they hopefully provide some incentive to look at why customers are ditching Vista and address their concerns.
