how to add outlook calander to other windows devices without using account (sharing to public)

[Wbutchart1]

Hi there, I am running the church calander from my outlook account. I want to be able to offer instructions to members as to how they can add it to their windows computers, but I cant seem to find any obvious way I can do this...I have managed with iPads so that any changes will automatically come up on their default calander but cant seem to do it with windows. I don't want everyone to have to sign up to a windows account but to instead be able to add the link to their calender, is this possible on windows as it is on iPads, I would assume it is but cant work out how to do it with one of the three sharing links that outlook gives.

Thanks.
