Newbie needs help

Hi,
I've got two questions.
I'm hosting a Mediawiki server on my windows 10 pc with XAMPP. If I use localhost It brings me to the localhost/dashboard. Is there a way to change it so It instantly bringes me to my mediawiki page?

If other people acces my site on their computers (with ip example: 192.168.10.90) they get on this site , only when they want to go to another page from the dashboard the Url changes from 192.168.10.90/dashboard to localhost/index/etc/etc/etc and then It gives an error that the site doesn't exist. But when I manualy change localhost to my ip adres it will find the page again. Is there a way to fix this?
