Windows Live Messenger is able to have group chat by simply inviting people in your contact list to your current chat window. Have you ever noticed that multiple conversation is really annoying because you’re automatically being pulled in when someone invites you? I’ve been invited many times to group chat but never really wondered how to disable the auto join into the chat. Thanks to Michael Y for bringing this to my attention because he wants to avoid getting automatically pulled into a multi convo every single time someone invites him. Sometimes, these conversations are so aimless that he leaves, but someone else always invites him in again!!! Moreover, this “feature” totally stops his downloads and he’ll have to download the file again from start.
I tried looking for a setting in Windows Live Messenger to stop group chat or at least show a warning window before automatically joining into the group chat. I was so surprised that there’s no such setting! Did the developers of Windows Live Messenger forgot to add this setting.
Fortunately, there’s a way to avoid joining into group chats automatically and you’ll also get a warning window first.
Just follow the few simple steps below to on how to avoid being automatically being pulled into group chats.
1. Make sure you have the latest Windows Live Messenger. If not, you can download from here and install.
2. Download Messenger Plus! Live and install. Look carefully after clicking Next during installation. It says “Messenger Plus! Live comes with an optional sponsor program. Make sure you select “I refuse to give my support, don’t install sponsor”. If not, you’ll have spyware on your computer.
3. Run Windows Live Messenger and sign in to your account.
4. Download Group Chat Warning script. Double click the script (gcwarning0-5.plsc) once finished downloading. Check “I accept responsiblity of installing this script” and click Import button.

When you get a new chat with more than 1 person, a window pops up, shows you who’s in that conversation, and lets you:

Accept…
– Does nothing but close the little warning window, so you can have the group chat like normal.
Decline…
– Tells the conversation “Please ask before starting group conversations”.
– Closes the Conversation.
The script did mention it does not actually avoid being invited into group chats, but it does make it easier to leave them. I tried this script, and I wasn’t automatically pulled into the group chat. The warning window appears first. Messenger Plus! Live is probably the coolest and most useful extension for Windows Live Messenger!
