Is there a way to get the git root directory in one command?

Let's say the repository starts at

C:\myrepo\
and the prompt is at 
C:\myrepo\folderone\folderoneb\folderonec

I need a batch script that can go up until it finds

Just use the command git rev-parse --show-toplevel and use its output in the way you need

And yes, this works on Windows, too ;)
