If you are wondering how to run multiple Yahoo! Messenger accounts within the same PC, here’s how it can be done by just applying a simple registry hack.
- Go to Start > Run.
- In the Run box, type regedit and click OK button to launch the Registry Editor.
- Now, navigate to HKEY_CURRENT_USER > Software > Yahoo > Pager > Test.
- On the right pane, right click , choose New > DWORD value.
- Rename the new registry key as Plural.
- Double click on the “Plural” registry key and assigns 1 as the value data.



Now, you can login to multiple Yahoo! Messenger accounts on your PC. If you want to login to two YM accounts, you will need to launch the application twice in order to get two login screens.

To disable or cancel this hack, just proceed and delete the “Plural” registry key.

Hi! I’ve been through a lot of research but can’t seem to find an answer. I’m just wondering if it’s possible to do this on a Mac too? I’ve done the same with my old Windows desktop and I love it. But now, I can’t find an answer to my dilemma. :’( Just hoping maybe you can help. Thanks!
