Ping me if you post instructions. Thanks.
I have a Netgear home router that has a built in web server I use to administer it. After logging in, I click the “Advanced” tab at the top, then expand “Security” on the left so I can see the options for “Block Sites”. Then I added “microsoft.com”, selected a radio button for “Keyword Blocking - Always” and finally click on the green “Apply” button at the top of the Block Sites window.
