mosquitto broker can't start after configuring password authentication

[twkwow]

basically i've installed mqtt mosquitto on windows, when I tried to configure the password files, it wont run. I suspect it is because it can't find the password file. I've tried mutiple password file paths in the mosquitto.conf like:

password_file "C:\Program Files\mosquitto\p1.txt"
password_file "C:\Program Files\mosquitto\p1"
password_file C:\Program Files\mosquitto\p1.txt
password_file C:\Program Files\mosquitto\p1
password_file C:\Progra ~ 1\mosquitto\p1.txt
password_file C:\Progra ~ 1\mosquitto\p1

all of the above can't seemed to work. If I don't use password configuration and allow_anonymous true, then it started running again. I'm running the mosquitto broker on my windows 10, using cmd with the command: net start mosquitto
