Return Value

RegistryKey

Remarks

The My.Computer.Registry object offers methods and properties for working with registry keys. See My.Computer.Registry Object for more information.

HKEY_USERS is primarily used to store default settings for first-time users.

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.
