Viewing and Managing Currently Running Programs
Software Explorer is a handy tool for working with your computer’s programs. You
can start Software Explorer by clicking Start
All Programs Windows Defender.
On the Windows Defender toolbar, click Tools
Software Explorer.
As shown in Figure 4-10, you can use Software Explorer to view and manage your
computer’s currently running programs and processes by selecting Currently Run-
ning Programs on the Category list. In the Name list, Software Explorer lists pro-
grams by name according to the software publisher. The process ID number of the
main process under which the program is running follows the program name.
You can use Software Explorer to work with your running programs in several ways.
You can view details about a running program’s configuration by clicking the pro-
gram in the left pane. Table 4-1 provides an overview of the summary details pro-
vided for running programs.

Chapter 4: Installing, Configuring, and Maintaining Software
You can also use Software Explorer to stop a program, which may be necessary, for
instance, if a program is not responding and you want to quit the program. While
you can view and work with currently running programs you started, you must have
administrator permission to view and work with running programs started by other
user or system accounts. To view currently running programs for other users and the
operating system, click “Show for all users.” When prompted, provide consent or cre-
dentials. You’ll then be able to view and work with all running programs and processes.
When you select a program or process in the left pane, you can terminate the pro-
cess by clicking End Process and then clicking Yes when prompted to confirm the
action. When you click the Task Manager button, Windows Vista opens Task Man-
ager. You can also open Task Manager by pressing Ctrl-Alt-Delete.
As Figure 4-11 shows, Task Manager has two tabs for working with running programs:
Applications
Lists applications you are currently running by name and status, such as Run-
ning or Not Responding. To exit a program, click the program in the Task list
and then click End Task.
Processes
Lists all programs and processes you are running on the computer by image
name, your username, and resource usage. To stop a process, click the process
and then click End Process.
