Viewer for Windows
Copyright 1995-2006 Igor Nys
PrcView is a process viewer utility that displays detailed
information about processes running under Windows. For each process it displays memory,
threads and module usage. For each DLL it shows full
path and version information. PrcView comes with a command
line version that allows you to write scripts to check if a process is running,
kill it, etc.

No special installation is required on Windows 95/98. Create a new, empty folder and

The main window shows you a list of running processes including information process Id,
priority, and full path to the process module. You can sort columns by clicking on the
Note that although you dont need to have administrative privilege on Windows NT
to run PrcView, list of task PrcView can access depends on your set of privileges.
Information about each loaded module including the module name, the module base address
in process space, the module size and full to the loaded module path.
You can display comprehensive version information by double-clicking
the appropriate line in the main or module
Information about all process threads including threads Id and priority. Note that if
PrcView uses Performance Data Helper to enumerate threads under Windows NT, it can take a

Just another way to kill a selected process. Note that killing a process can cause
undesired results including loss of data and system instability. The process will not be
given a chance to save its state or data before it is terminated. It is advisable to try
the "Notify" button in the "Kill" dialog to close a GUI-based
application first (via WM_SYSCOMMAND)
Nice way to attach a debugger to a running application. PrcView reads the
"AeDebug" key and starts a registered debug application. PrcView allows you not
only to select a process to debug but also to associate a particular project with it. This
is especially useful while debugging an DLL that has a separate project. Associations are
stored in the registry.
Set priority class
Allows you to specify a new priority class for the selected process.
The Process Finder Tool
With the Process Finder Tool you can find the process corresponding to a
selected window. To find a process:

- Press the Find Process button on the toolbar.
- Keep left mouse button pressed while dragging the Finder Tool to the desired window.
- Release mouse button. PrcView will select the corresponding process in the main view.
Shows you the process hierarchy for all running processes. You can select the desired
task by clicking on the process item in the Process Tree window.

module base address in process space, the module size and full to the loaded module path.
Selecting a module from the module list shows only processes witch use a selected module.
Selecting "Module Usage" again returns the main window to the original process

line in the window.
Shows all top-level window titles. You can select the desired task by clicking on the

Allow Multiply Instances If turned "on", PrcView allows to start
more than one instance of the program. If turned "off" the instance of PrcView
that is already running will be activated.
