Reading from the registry – Involves disk? Limitation on reading access?

Does reading involve the disk or is it RAM only?

Is it always available for reading, or are there any limitations such as certain users who will have demoted security and will not be able to?

The registry is stored on disk, but will be cached (to some extent) so you are basically reading from disk though there will be times when you'll get the cached version.

While, in general, all users have read only access to the registry, there will be parts (other user profiles, for example) that won't be accessible.

You should always have read only access to HKEY_LOCAL_MACHINE (with the exception of HKEY_LOCAL_MACHINE\SAM and HKEY_LOCAL_MACHINE\SECURITY are restricted and can only be read with local system privilege) and HKEY_CURRENT_USER.
