A larger number of these utilities are nowadays bundled by the publishers for the sake of simpler downloading of all, or most, current versions in the so-called Sysinternals Suite. NTFSDOS, which allowed NTFS volumes to be read by Microsoft's MS-DOS operating system, is now discontinued and is no longer available for download. Windows Sysinternals supplies users with numerous free utilities, most of which are being actively developed by Mark Russinovich and Bryce Cogswell, such as Process Explorer, an advanced version of Windows Task Manager, Autoruns, which Windows Sysinternals claims is the most advanced manager of startup applications, RootkitRevealer, a rootkit detection utility, Contig, PageDefrag and a total of 65 other utilities. In late 2010, Bryce Cogswell retired from Sysinternals. Currently, the Sysinternals website is moved to the Windows Sysinternals website and is a part of Microsoft Docs. Most of the source that Sysinternals provided was also removed. However, NT Locksmith, a Windows password recovery utility, was immediately removed. Russinovich explained that Sysinternals will remain active until Microsoft agrees on a method of distributing the tools provided there. On July 18, 2006, Microsoft Corporation acquired the company and its assets. Winternals Software LP was founded by Bryce Cogswell and Mark Russinovich, who sparked the 2005 Sony BMG CD copy protection scandal in an October 2005 posting to the Sysinternals blog. The company also sold data recovery utilities and professional editions of their freeware tools. The software can now be found at Microsoft. The website featured several freeware tools to administer and monitor computers running Microsoft Windows. Microsoft acquired Winternals and its assets on July 18, 2006. It was started by software developers Bryce Cogswell and Mark Russinovich. Originally, the Sysinternals website (formerly known as ntinternals ) was created in 1996 and was operated by the company Winternals Software LP, which was located in Austin, Texas.
