SysInternals

SysInternals (recently swallowed by Microsoft) has produced a good number of tools that are handy in developing apps and debugging systems. Here are some of the highlights:


 * Process Explorer
 * Find out what files, registry keys and other objects processes have open, which DLLs they have loaded, and more. This uniquely powerful utility will even show you who owns each process.


 * Autoruns
 * See what programs are configured to startup automatically when your system boots and you login. Autoruns also shows you the full list of Registry and file locations where applications can configure auto-start settings.


 * BlueScreen
 * This screen saver not only accurately simulates Blue Screens, but simulated reboots as well (complete with CHKDSK), and works on Windows NT 4, Windows 2000, Windows XP, Server 2003 and Windows 9x.


 * ZoomIt
 * Presentation utility for zooming and drawing on the screen.
