How do I change my display name?

 

dude .. your seriously asking?

Tools --> Option

 

Lol I am not an idiot, when I do that it is grey and not changeable.

 

If it's no Hotmail-Account, you should try to re-activate your address's Passport .NET >> https://accountservices.passport.net/

Hope this helps..

and else you can try to change your Display-Name online >> http://www.blockstatus.com/msn/nick-changer
