Ever wondered which program has a particular file or directory open? Now you can find out. Process Explorer shows you information about which handles and DLLs processes have opened or loaded. The Process Explorer display consists of two sub-windows. The top window always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that Process Explorer is in: if it is in handle mode you'll see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you'll see the DLLs and memory-mapped files that the process has loaded. Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded. The unique capabilities of Process Explorer make it useful for tracking down DLL-version problems or handle leaks, and provide insight into the way Windows and applications work. Process Explorer works on Windows 9x/Me, Windows NT 4.0, Windows 2000, Windows XP, Server 2003, and 64-bit versions of Windows for x64 and IA64 processors, and Windows Vista.
What's new in Version 11.03:
* This update to Process Explorer, an advanced process information utility, has a number of miscellaneous improvements. For example, the thread support in the process properties dialog is enhanced with Wow64 thread stacks on 64-bit Windows and kernel stacks on Windows Vista and Server 2008. In addition, tooltips on the service hosting processes now show service names, the user SID is displayed on the security properties page, and column headers have tooltips when they're too small to display their text.
