title: How to reset the user/password of Jenkins on Windows?
body: <p>Maybe a fool question, I installed jenkins on windows by default, have set no user/password, it worked at first, no need to login. But when launch the 8080 webpage now, it hangs the login page, I've tried some normal user/password combinations, none could pass. Also searched the resolution on website, only find some about linux, no about windows, so need help.
