This article discusses some of the variables to consider
when you run both Windows Messenger and MSN Messenger 5.0 on a Microsoft
Windows XP-based computer.
Windows Messenger is included with Windows XP and is
installed when you install the operating system.
MSN Messenger 5.0 is
included with MSN 8.0 and is also available as a separate download. It is
installed on your computer when you install MSN 8.0 or when you run MSN
Messenger 5.0 Setup. If you are running Windows Messenger 4.x
, and you previously installed the MSN Add-in for Windows
Messenger, you may receive a message to install MSN Messenger 5.0. If you did
not install the MSN Add-in for Windows Messenger, you are not prompted to
install MSN Messenger 5.0.Notes
- You cannot run both Windows Messenger and MSN Messenger 5.0
on non-Windows XP-based computers. You cannot install Windows Messenger on
non-Windows XP-based computers.
- You cannot run both Windows Messenger and MSN Messenger
versions earlier than version 5.0 on Windows XP-based computers. You cannot
install versions of MSN Messenger earlier than MSN Messenger 5.0 on Windows
Differences between MSN Messenger 5.0 and Windows Messenger
- Only Windows Messenger can connect to the Communications
Service and Microsoft Exchange Instant Messaging.
Service account provides instant messaging in a corporation or in a network. To use
a Communications Service account, your company must be using Session Initiation Protocol (SIP) technology. If you are not sure whether your
Messenger program permits the use of a Communications Service account, ask your
network administrator. With a Communications Service account, you can send
instant messages in your corporate network, add other Communications
Service users to your contacts list, talk with another Communications Service
user by using microphones, and send a file to another Communications Service
With Exchange Instant Messaging, Messenger users who are in the same corporation or who use the same
computer network can communicate in real time. Exchange Instant Messaging is available to corporations and
networks that use Microsoft Exchange 2000 Server.
- MSN Messenger 5.0 does not support Messenger application
programming interfaces (APIs) when it is installed on Windows XP-based
computers. Messenger APIs are used to create custom Messenger programs. If you
are running Windows XP and you want to use custom Messenger programs, you must
use Windows Messenger. For additional information about Messenger APIs, visit
the following Microsoft Web site:Note Microsoft Outlook 2002, Microsoft Outlook Express 6, and the
Remote Assistance feature in Windows XP are examples of programs that use these
APIs and depend on Windows Messenger.
Running both MSN Messenger 5.0 and Windows Messenger
- By default, some programs automatically connect to Windows Messenger. Such programs include Microsoft Outlook, Microsoft Outlook Express, and Remote
Assistance. When you are signed in to
MSN Messenger, you may appear to be offline to people who connect to these
programs and have you listed as a contact.
- You can configure Windows Messenger or MSN Messenger
to start automatically when Windows starts. Only one Messenger
program can start automatically when Windows starts. You can start the other
program from your list of programs. (In Windows, click Start,
point to All Programs, and then click the program that you
want to start).
If both Windows Messenger and MSN Messenger are
configured to start automatically when Windows starts, and Windows Messenger is
not configured for corporate instant messaging, the Run this program
when Windows starts option in Windows Messenger is turned off, and MSN
Messenger starts automatically when Windows starts. However, if you configured
Windows Messenger for corporate instant messaging and to start automatically
when you start Windows, it continues to do this and MSN Messenger does not start
- You can run Windows Messenger and MSN Messenger on a
Windows XP-based computer at the same time. However, you cannot sign in to both
MSN Messenger and Windows Messenger by using the same Microsoft .NET Passport
at the same time.
Note With the .NET Passport online service, you can use your e-mail address and a single password to sign in to any .NET Passport-participating Web site or service.
If you are signed in to one Messenger program with
your .NET Passport, and then you use the same account to sign in to the other program, you are automatically signed off the first Messenger program. You must
sign in to both Messenger programs by using different .NET Passport accounts.
For example, you can sign in to MSN Messenger with your .NET Passport account,
and then sign in to Windows Messenger with a different .NET Passport account or
with your corporate instant messaging account.
- When you run both Messenger programs, icons for each of the
programs appear in the notification area at the far right of the
taskbar. Unlike the Windows Messenger icon, the MSN Messenger icon includes the
image of a butterfly. You can also position your mouse pointer over each icon.
When you do this, a message appears that identifies whether the program is
Windows Messenger or MSN Messenger.
How to run only one or both Messenger programs
The following methods describe different configuration options for
running only one or both Messenger programs.
Method 1: You want to use only Windows Messenger
If you want to use only Windows Messenger, remove MSN Messenger
5.0. To remove MSN Messenger 5.0, follow these steps:
- Click Start, click Control Panel, and then click Add or Remove
- In the list of currently installed programs, click
MSN Messenger 5.0, and then click
- Click Yes when you are prompted to confirm
Method 2: You want to use MSN Messenger 5.0 and Windows Messenger
If you want to use MSN Messenger 5.0 and Windows Messenger,
configure each Messenger program with the appropriate options. For example, if
you want to use MSN Messenger 5.0 as your primary instant messaging program but
also use Windows Messenger for those services and programs that require it (such as Communications Service, Microsoft Exchange Instant Messaging, Outlook,
Outlook Express, or Remote Assistance), configure Windows Messenger not to start automatically when Windows starts. After you do this, you can start
Windows Messenger from the Start
menu to connect to a
Communications Service or Exchange Instant Messaging, or to sign in to the .NET
Messenger Service with a different .NET Passport account. To configure Windows
Messenger not to start automatically when Windows starts, follow these steps:
- In the notification area, right-click Windows
Messenger, and then click Open.
- On the Tools menu, click
- Click the Preferences tab.
- Clear the Run this program when Windows
starts check box, and then click OK.
If you want other programs to run Windows Messenger but you do not have to run Windows
Messenger to connect to a Communications Service or Exchange Instant Messaging,
or if you want to sign in to the .NET Messenger Service with a different .NET Passport
account, use the Set Program Access and Defaults feature that is included with Windows
XP Service Pack 1 (SP1) to hide the Windows Messenger icons.
