On my private Windows 10 Pro machine, I only use local accounts, no Microsoft accounts. I have, some time ago, created further local accounts for my family members, and all is well.
One Steam game I installed for one of those local accounts cannot be started; when I do so, I get the message "Parental Controls have prevent this application from running".
Similar to this question How to setup login time limits (a.k.a. "parental controls") if you don't want to login with a Microsoft account? I have never linked any account on that machine to a Microsoft account. As the family/parental controls are only accessible if you do so, I am very sure that I have never activated those (and sure enough, if I try to enter them through Settings => Family..., I immediately get sent off to Microsoft's website/login screen).
I am familiar with regedit and gpedit... where could I go looking to see whether parental controls are actually enabled, and how to disable them locally?
EDIT: Added the actual english message, thanks to @Ramhound's comment.
