OSRONLINE is OSR's Legacy Community Site

For information about our OSR's seminars and services, please visit our Corporate site at http://www.osr.com.

Welcome to OSR's original community web site, named "OSRONLINE." Established back in 2004, it contains articles from the first ten years from The NT Insider, as well as other historical content.

Today, this site still hosts and maintains two active imporant functions: We will eventually be moving these functions (and all the old OSRONLINE.COM content) to a modern (and far less ugly) site that we've been developing. That will take us quite a while. Until that time, we maintain this site for your use.

New, up-to-date posts in the OSR's staff's Developer's Blog can be found on our new Corporate site. All the content from The NT Insider (OSR's journal of Windows system software development) can also be found on OSR.COM.

To access the new OSR Corporate site please visit http://www.osr.com.
OSR Dev Blog posts are now being created and posted at http://www.osr.com/developers-blog/. Please check that location for future posts. We are listing the most recent posts from that site here, as a convenience. See the full list of our blog posts here.
