Remarks

HKEY_LOCAL_MACHINE is usually used to store settings that do not vary from user to user in Windows. All users of the computer share this key. Its five subkeys (Hardware, SAM, Security, Software, and System) hold configuration data for the local machine.

The RegistryPermission class, which is in the System.Security.Permissions namespace, controls access to registry variables. Registry variables should not be stored in memory locations where code without RegistryPermission can access them. Similarly, when granting permissions, grant the fewest privileges necessary to get the job done.

Registry permission access values are defined by the RegistryPermissionAccess enumeration. The following table details its members.

Value Description
AllAccess Create, read, and write access to registry variables.
Create Create access to registry variables.
NoAccess No access to registry variables.
Read Read access to registry variables.
Write Write access to registry variables.
