Registry
Synopsis
This class is the starting point
when using the Windows registry,
which is the central repository used by most Windows applications for
storing user-specific settings and preferences. Each static field of
this class represents a root RegistryKey
object,
which has values and multiple levels of subkeys. These keys are
read-only, but can be manipulated using the methods of the
RegistryKey
class.
Most applications store their settings in
CurrentUser
(HKEY_CURRENT_USER). The recommended
standard is to use the Software
subkey, create a
subkey for your organization, and then create a subkey for each
specific application (for example, Internet Explorer preferences are
stored in HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer).
Analogous global settings that should affect all users on the current
computer can be placed in a similar subkey in
LocalMachine
(HKEY_LOCAL_MACHINE). For example,
setup programs often use this key to store information about
installed applications. The full collection of user settings for all
the users of the current computer can be retrieved from the
Users
key, as can the default settings for new
users, which are contained in the .DEFAULT
subkey
of users. CurrentUser
is actually a mapped subkey
of Users
, much as CurrentConfig
is a subkey of LocalMachine
.
The ClassesRoot
key contains information used for Windows 3.1-compatible DDE and OLE support. Information for file viewers, Windows Explorer extensions, and file associations is also stored ...
