Alla registernycklar är containrar, så den enda arvsflagga som är meningsfull för registernycklar är InheritanceFlags.ContainerInherit flaggan. Om den här flaggan inte anges ignoreras spridningsflaggor och endast den omedelbara nyckeln påverkas. Om flaggan finns sprids regeln enligt följande tabell. Tabellen förutsätter att det finns en undernyckel S med undernyckeln CS och undernyckeln GS för barnbarn. Sökvägen för undernyckeln barnbarn är S\CS\GS.

Mönstret för undernyckeln barnbarn styr alla undernycklar som ingår i undernyckeln barnbarn.

Om ContainerInherit flaggan till exempel har angetts för inheritanceFlags och InheritOnly spridningsflaggan har angetts för propagationFlagsgäller den här regeln inte för den omedelbara undernyckeln, utan gäller för alla dess omedelbara underordnade undernycklar och för alla undernycklar som de innehåller.

Exempel

I följande kodexempel visas åtkomstregler med arv och spridning. Exemplet skapar ett RegistrySecurity objekt och skapar och lägger sedan till två regler som har ContainerInherit flaggan. Den första regeln har inga spridningsflaggor, medan den andra har NoPropagateInherit och InheritOnly.

Programmet visar reglerna i RegistrySecurity objektet och använder RegistrySecurity sedan objektet för att skapa en undernyckel. Programmet skapar en undernyckel och en undernyckel för barnbarn och visar sedan reglerna för varje undernyckel. Slutligen tar programmet bort testnycklarna.
