Microsoft said my Vaio is compatible, but Sony says No

The problem with proprietary computers such as Sony Vaios is that Sony installed all such accessories on the motherboard. A fact that most buyers never take into consideration. Back in 2005 this was the only way to get your hands on Microsoft Windows Media Centre Edition 2005. It was far different then than it is now. But thanks anyway.

I Have a Sony Vaio and wanted to upgrade. I did buy a Hauppauge tuner and installed it and updated the realtek sound drivers and I am having no additional problems running windows 7 on it. When you install, you do have to do a new install because it is not running vista.
