Updates Disabled by System Administrator

So I know this question has been asked and answered in various scenarios but so far I've not found one matching mine. Personal PC. I'm on V 131.0.2 since a reinstall last year but only now realised no updates have been done since because of this msg. I've worked through the various fixes others used re policies, but I can't locate any policy files in the various locations suggested; registry editor (HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox key (don't have it) & others, about:config (nothing showing on a search), Program Files/Policies (don't have it), C:\Program Files\Mozilla Firefox\Distribution folder (don't have it). So I could not find the offending poicy DisableAppUpdate anywhere in locations offered by other posters etc. Rather than taking forever to pin down the culprit, can I not just manually update to the latest version or will that delete all my settings/extensions etc?? Given how often it's crashing I'm almost tempted down that road except that I like to have my History intact as I often want to find a site I've not bookmarked. Thanks.
