Microsoft has closed access to the source code utilities Sysinternals

In 2006, Microsoft bought Sysinternals . The developers Mark Russinovich and Bruce Cogswell wrote a large number of useful system utilities for managing, diagnosing, troubleshooting and monitoring the Microsoft Windows environment.

Sysinternals has become part of Microsoft Technet, utilities are still available for download here and here . But before buying the company, it was possible to download the source codes of the programs on the site, and now the source codes are not available.

Microsoft claims that the source code has been removed due to the fact that its availability may cause problems with the support of other components of Windows.

The Sysinternals program sources showed features such as hiding information in the registry, intercepting and connecting API functions for monitoring the file system and other interesting things. Often, the programs used the undocumented Native API functions to perform actions that are impossible using standard WinAPI.

Fortunately, someone put a mirror of Sysinternals site on July 18, 2006 (the date of the company's purchase) on torrents, which contains not only the site pages, but all utilities and source code.
