How do I change "Windows User" in Comments box to my own name?

[KBM Consultants]

When I insert a Comment, instead of my name as the precursor, I get "Windows
User". How do I change this (as opposed to just editing it every time)?

Tools->Options, in the General tab look for "User name"

I should have made it clear it is Excel 2007 - but it prompted me to find the
answer.

Office button - Prepare - Properties - "User Name".

Thanks
