Why is this an Emacs problem?  It's a typical Windows messup, whereby
some directories are "owned" by the Administrators _group_ instead of
by your user.  Just fire up the File Explorer, and make it change the
owner of wherever you keep your Git repository to your user,
recursively.

Which is what you should do.  In general, make every directory where
you or your applications create files to be owned by your user, and
make sure they will inherit the ownership to any subdirectories.

I see no reason to decide that this has anything to do with Emacs.
That's a slippery slope, especially given that no one is lately
interested in maintaining the Windows port of Emacs.
