Every time you start up your computer, Messenger also starts up which can slow everything down and use up more system resources. To uninstall it:
1. Click on the Start button and select Run.
2. Type "RunDll32 advpack.dll,LaunchINFSection %windir%\INF\msmsgs.inf,BLC.Remove" in the text box and click OK. You will see a progress bar appear shortly as it deletes its files and it will then ask you to reboot. After the reboot the program will be gone.

Put the ability to remove the application back in the Add/Remove options in the conrol panel of Windows XP
For some reason, Microsoft has removed the ability to specify which Windows components you want to install during interactive Setup, and when you go into Add/Remove Windows Components in the Control Panel, you still don't have the full list of applications and applets you can add and remove. Thankfully, this is easy to fix.
To dramatically expand the list of applications you can remove from Windows XP after installation, navigate to C:\WINDOWS\inf (substituting the correct drive letter for your version of Windows) and open the sysoc.inf file. Under Windows XP Professional Edition RC1, this file will resemble the following by default:
[Version] Signature = "$Windows NT$"
DriverVer=06/26/2001,5.1.2505.0
[Components]
NtComponents=ntoc.dll,NtOcSetupProc,,4
WBEM=ocgen.dll,OcEntry,wbemoc.inf,hide,7

[Global]
WindowTitle=%WindowTitle%
WindowTitle.StandAlone="*"
The entries that include the text hide or HIDE will not show up in Add/Remove Windows Components by default. To fix this, do a global search and replace for ,hide and change each instance of this to , (a comma). Then, save the file, relaunch Add/Remove Windows Components, and tweak the installed applications to your heart's content.

If you'd just like Windows Messenger to show up in the list of programs you can add and remove from Windows, navigate to C:\WINDOWS\inf (substituting the correct drive letter for your version of Windows) and open sysoc.inf (see the previous tip for more information about this file). You'll see a line that reads:
msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,hide,7
Change this to the following and Windows Messenger will appear in Add or Remove Programs, then Add/Remove Windows Components, then , and you can remove it for good:
msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,,7
