Maximum Open Files

You requested maxclients of 10000 requiring at least 10032 max file descriptors.
Server can't set maximum open files to 10032 because of OS error: Operation not permitted.
Current maximum open files is 4096. maxclients has been reduced to 4064 to compensate for maxclients has been reduced to 4064 to compensate for low ulimit. If you need higher maxclients increase 'ulimit -n'.

Setup SSH Authentication for Git Bash on Windows

Prepararation

Create a folder at the root of your user home folder (Example: C:/Users/uname/) called .ssh.
