The Sysinternals site divides the utilities into six main categories: file and disk, networking, process, security, system information and miscellaneous.

In 2006, Microsoft acquired Winternals and Sysinternals. In 1998, the NT Internals site was renamed to Sysinternals after Microsoft's legal department noted the similarity to the name of the Windows NT operating system and requested the change. Next, the duo sold commercial versions of their security and recovery utilities for the Windows platform at a company named Winternals Software. They released their first free application, named NTFSDOS, which enabled an MS-DOS machine to read NTFS volumes. Russinovich and Cogswell started a site named NT Internals in 1996 that hosted the Sysinternals freeware utilities and related articles.

For example, the features in RegMon and FileMon were absorbed into the Process Monitor tool. Some utilities no longer exist as stand-alone applications after their functionality moved to other Sysinternals applications. Certain applications that have no troubleshooting features are not included in the Sysinternals suite download, such as BlueScreen, which emulates the blue screen of death and can be used as a screensaver.Ĭogswell retired from Microsoft in 2010, but Russinovich - currently CTO of the Microsoft Azure cloud platform - continues to update the utilities and develop new additions to the Sysinternals suite. Administrators can access the utilities from TechNet - either as a single suite download or individually - or run them directly from the Sysinternals Live service. These utilities are executable files that do not require installation to run.

Windows Sysinternals is a suite of more than 70 freeware utilities that was initially developed by Mark Russinovich and Bryce Cogswell that is used to monitor, manage and troubleshoot the Windows operating system, and which Microsoft now owns and hosts on its TechNet site.
