Requesting Additional Secure Registry Keys (Windows CE 5.0)
To request additional secure registry keys, use IOCTL_HAL_GETREGSECUREKEYS. The IOCTL will be called twice, first to request the size of the buffer required to hold the key names, and a second time to fill that buffer.
The security provided by this IOCTL_HAL_GETREGSECUREKEYS is very large-grained. Untrusted applications may not create, modify, or delete any data underneath the provided key name in any root registry key. However, untrusted applications may still read the protected data.
