Windows System Software -- Consulting, Training, Development -- Engineering Excellent, Every Time.
Getting started writing Windows drivers and/or minifilters: What you need to know.

We Live Windows Drivers, File Systems, and Debugging

At OSR, we’re experts in operating system software: Windows device drivers, Windows file systems, debugging complex Windows problems, and most things related to Windows internals. System software is all we do.  And, over the past 20 years, people tell us we’ve gotten pretty good at it.  Along the way, we’ve even become pretty decent at doing certain kernel-mode software on Linux.

Let us help with your Windows system software project.  Whether it’s one day of consulting for an informal design review and discussion, a multi-day class taught by one of our experienced engineers, or end-to-end custom design and development of your driver, your project can benefit from our definitive expertise.
