How badly did Microsoft screw up the Vista “upgrade?” So badly, even the company’s top executives were upset: They Criticized Vista. And They Should Know.

Here’s one story of a Vista upgrade early last year that did not go well. Jon, let’s call him, (bear with me — I’ll reveal his full identity later) upgrades two XP machines to Vista. Then he discovers that his printer, regular scanner and film scanner lack Vista drivers. He has to stick with XP on one machine just so he can continue to use the peripherals.

Did Jon simply have bad luck? Apparently not. When another person, Steven, hears about Jon’s woes, he says drivers are missing in every category — “this is the same across the whole ecosystem.”

Then there’s Mike, who buys a laptop that has a reassuring “Windows Vista Capable” logo affixed. He thinks that he will be able to run Vista in all of its glory, as well as favorite Microsoft programs like Movie Maker. His report: “I personally got burned.” His new laptop — logo or no logo — lacks the necessary graphics chip and can run neither his favorite video-editing software nor anything but a hobbled version of Vista. “I now have a $2,100 e-mail machine,” he says.

It turns out that Mike is clearly not a naïf. He’s Mike Nash, a Microsoft vice president who oversees Windows product management. And Jon, who is dismayed to learn that the drivers he needs don’t exist? That’s Jon A. Shirley, a Microsoft board member and former president and chief operating officer. And Steven, who reports that missing drivers are anything but exceptional, is in a good position to know: he’s Steven Sinofsky, the company’s senior vice president responsible for Windows.
