Internal e-mails indicate that Microsoft executives struggled to make Vista work properly, fuelling the flames of a class action suit brought by customers whose "Vista capable" computers cannot run advanced Vista features.
The mails show that management at the software giant were aware of the issues even before Vista launched – but still went ahead with the launch, and with labelling PCs based on the Intel 915 chipset as "Vista capable".
In addition, they knew that many drivers weren't available at the time of the launch.
Mike Nash, vice-president of Windows Product Management at Microsoft, wrote in an e-mail: ""I personally got burned by the Intel 915 chipset issue on a laptop. I chose my laptop because it had the Vista logo and was pretty disappointed. I now have a $2 100.00 e-mail machine."
Steven Sinofsky, the Microsoft executive in charge of Windows, struggled to get his home printer working with Vista and wrote as much to CEO Steve Ballmer in February last year.
The documents could imply that Microsoft bowed to pressure from hardware partners to certify some computers.
