Multiple Instances of Yahoo! Messenger

Yahoo! India LogoBasically, Yahoo! Messenger doesn’t offer multiple instances. Use this tiny registry hack to use multiple instances. This works for all versions up to 9.0. We’ll be using Registry Editor and a DWORD value to override it’s default single instance.

Open Registry Editor.

  • Navigate to


  • Create a DWORD (Right Click->New->DWORD Value) Value  named “Plural” (without quotes)
  • Assign it a value ‘1‘ and click OK.
  • Open Yahoo! Messenger just as you would normally. Every time you open Yahoo! Messenger, you’ll be presented with a new instance.

To Disable Multiple Instances, simply remove the DWORD value you just created (or) assign it a value ‘0‘.
