Hello

I have a new windows 8.1 machine.
I set up the user details with my microsoft hotmail address.
I then signed out and made the account local.
But when I installed Open Office it asks me to set it up for just the current user account or everyone.
The option for the current user is my hotmail address. Even though I changed it.
I suspect if I install other programmes it will detect my hotmail account as the user even though it isn't
How can I change that.
Thanks
