Registry blocking rule options

Registry blocking rules prevent users and unauthorized programs from altering, opening, or deleting specified registry keys and values.

Note: When creating a registry blocking rule, use the best matching hive registry subtree abbreviation. For example, to block HKLM\System\CurrentControlSet\Services\MyService, choose the HKCCS hive rather than HKLM.
