What do you mean by a "Windows share"?  Are you talking about a
directory on your local machine or a network share provided by a remote
system?

Try checking the ACLs on the .git directory using the Windows file
explorer and make sure that you have the Change Permissions right.  If
your user is listed as having Full Control, then you have the right, but
you'll have to use the advanced view for your user's permission entry to
check for certain if you do not have Full Control.

Just as a guess, are you using a Windows-native build of git as well?
I'm not sure if it makes a difference or not, but it could be a good
data point to consider.
