Windows 7 Tip: 
Last Week i reinstall my Windows XP copy and removed all the junk files and soft from my pc, but only one thing that annoying me regularly is MSN Messenger. I am not the regular User Of MSN. So am sharing with you this tip to how to remove MSN from PC.
How to Uninstall MSN Messenger
- Ensure MSN Messenger is completely closed out, and exit from the system tray icon. Alternatively, you can end the process “msnmsgr.exe“.
- Click onto Start
Then Run 
- Next, simply copy and paste this command:
RunDll32 advpack.dll,LaunchINFSection %windir%\INF\msmsgs.inf,BLC.Remove - Finally, click OK. Wait a moment for it to finish. Reboot to verify it’s uninstalled.
If you want to reinstall MSN? Don,t Worry Microsoft definitely has that option. Just go to Microsoft’s MSN Live Messenger website and redownload it.
Great information. Also wanted to let you know about the program I developed to do the same thing.
