Process Explorer
process explorer
Process Explorer is a freeware task manager and system monitor for Microsoft Windows created by SysInternals, which has been acquired by Microsoft and re-branded as Windows Sysinternals. It provides the functionality of Windows Task Manager along with a rich set of features for collecting information about processes running on the user's system. It can be used as the first step in debugging software or system problems.
Process Explorer can be used to track down problems. For example, it provides a means to list or search for named resources that are held by a process or all processes. This can be used to track down what is holding a file open and preventing its use by another program. As another example, it can show the command lines used to start a program, allowing otherwise identical processes to be distinguished. Like Task Manager, it can show a process that is maxing out the CPU, but unlike Task Manager it can show which thread (with the callstack) is using the CPU – information that is not even available under a debugger.
History
Process Explorer began in the early Sysinternals days as two separate utilities, HandleEx and DLLView, which were merged in 2001. Until 2008, Process Explorer worked on Windows 9x, Windows NT 4.0 and Windows 2000.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Process Explorer”, the useful work is to connect “process explorer” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q1567949. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2001, 2008 and 2000.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
