Windows: a software engineering odyssey | Patreon

This is a text transcription of the slides from the "Windows: a software engineering odyssey" talk given on Microsoft culture by Mark Lucovsky in 2000. This is hosted here because I wanted to link to the slides, but the only formats available online were powerpoint and slide-per-page HTML where each page is basically a screenshot of a powerpoint slide. If you're looking for something on current Microsoft culture, try these links.
