Did you know there is an extra hidden tab in Windows Live Messenger Option dialog box? Its called "Add-in". I don’t know why its hidden by default? Today I found a registry hack to enable it in WLM while playing with WLM’s EXE file in Resource Hacker.

After:
So here is step-by-step tutorial to enable it:
1. Open regedit and goto:
HKEY_CURRENT_USER\Software\Microsoft\MSNMessenger
2. In right-side pane, create a new DWORD value and give it name “AddInFeatureEnabled” and set its value to 1
3. Thats it. Now open Windows Live Messenger and goto “Tools -> Options” and you’ll see a new tab "Add-ins" at last.
