SUMMARY
This article describes how to prevent Windows Messenger
from running. By default, Windows XP Professional and
Windows XP Home Edition install Windows Messenger, and
the user interface does not provide a way to remove or to
uninstall Windows Messenger.
When you install Windows XP Service Pack 1 (SP1), Windows
adds a new feature that is named "Set Program Access and
Defaults" to the Add or Remove Programs tool in Control
Panel. You can use this feature to remove Windows
Messenger from the Start menu, the desktop, and other
locations. For additional information, click the

or Remove Access to Microsoft Windows and Non-Microsoft
Programs
MORE INFORMATION
WARNING: If you use Registry Editor incorrectly, you may
cause serious problems that may require you to reinstall
your operating system. Microsoft cannot guarantee that
you can solve problems that result from using Registry
Editor incorrectly. Use Registry Editor at your own risk.
To prevent Windows Messenger from running, use one of the
following methods.
Windows Messenger 4.0 or Later on a Windows XP
Professional-Based Computer
1. Click Start, click Run, type gpedit.msc, and then
press ENTER.
2. Double-click the following items to expand them:
.. Local Computer Policy
.. Computer Configuration
.. Administrative Templates
.. Windows Components
.. Windows Messenger
3. Double-click Do not allow Windows Messenger to
run, and then click Enabled.
4. Click OK, and then quit the Group Policy snap-in.
NOTE: Group Policy Editor (Gpedit.msc) is not available
on Windows XP Home Edition-based computers.
NOTE: This method also prevents programs that use the

using Windows Messenger. Microsoft Outlook 2002,
Microsoft Outlook Express 6, and the Remote Assistance
feature in Windows XP are examples of programs that use
these APIs and that depend on Windows Messenger.
