    So I go into Control Panel, Default Programs, Set Associations, navigate to .prc. It's currently set to 2008.

    I get the choice of V17 and 2008 versions of SSMS under Recommended Programs. I click on the V17 icon... and the list re-loads and it's still pointing to 2008.

    It sounds like it's just pointing to the 2008 version. Check this link and see if it helps - has some solutions for the same issue:
    Opening .sql files in SSMS 2012 as default program and with existing instance

    I use FileTypesMan from NirSoft as I can view a lot more of where things are pointing - especially for multiple apps like SSMS:
