Microsoft Manual of Style

The Microsoft Manual of Style: Your Everyday Guide to Usage, Terminology, and Style for Professional Technical Communications (MSTP), in former editions the Microsoft Manual of Style for Technical Publications, was a style guide published by Microsoft. The fourth edition, ISBN 0-7356-4871-9, was published in 2012. Microsoft employees and partners also had access to a Microsoft Compressed HTML Help (CHM) version.

In 2018, the book was replaced by a website, the Microsoft Writing Style Guide, joining other online guides like the Apple Style Guide and Google Developer Documentation Style Guide.
