Reading from and Writing to the Registry Using My

Working with the registry may compromise security by allowing inappropriate access to system resources or protected information. To use these properties, you must have read and write permissions from the RegistryPermissionAccess enumeration, which controls access to registry variables. Any code running with full trust (under the default security policy, this is any code installed on the user's local hard disk) has the necessary permissions to access the registry. For more information, see RegistryPermission class.
Registry variables should not be stored in memory locations where code without RegistryPermission can access them. Similarly, when granting permissions, grant the minimum privileges necessary to get the job done.
