Re: Does that mean that Microsoft will try to identify bugs before it releases its updates/patches?
A collection of very low latency I/O libraries that a -lot- of games and drivers used. Pretty much if you needed a user-mode bit of code to safely read/write from a peripheral's memory, we were your first stop. Our code eventually replaced a bunch of components of DirectX, and the Windows Driver Framework, and became part of Hyper-V.
We were brought into the fold during the Longhorn development period in 2004 when they decided to reset all their development efforts. We were scooped up to save time in developing code that they had failed to write properly the first time around, or hadn't gotten around to writing it yet.
