Somehow, my global git (msysgit) settings for user.name and user.email (and god knows what else) are set to a recent ex-colleague's details.

When I try and change them i get could not commit to u://.gitconfig

If I try and create u://.gitconfig through git bash then i get permission denied.

C:\Users\<My Username>\

contains no references to git.

I've tried uninstalling, searching the registry and my file system for all references to git and I can't find any (windows file search is crap though).

What the hell is going on? Why even after reinstalling are this guys details still the global settings???

Thanks
