How I kill time…. :)

Close Windows Messenger if its open, or active in your System Tray.

Click Start, Run and enter the following command:
RunDll32 advpack.dll,LaunchINFSection %windir%\inf\msmsgs.inf,BLC.Remove

Note: This will prevent a long delay when opening Outlook Express if you have the Contacts pane enabled.

To prevent this, click Start, Run and enter REGEDIT Go to:
HKEY_LOCAL_MACHINE\Software\Microsoft\Outlook Express

Right click in the right pane and select New, Dword value. Give it the name Hide Messenger Double click this new entry and set the value to 2.
