Retrieved 1 April Many programming languages offer built-in runtime library functions or classes that wrap the underlying Windows APIs and thereby enable programs to store settings in the registry e. Technically, they are predefined handles with known constant values to specific keys that are either maintained in memory, or stored in hive files stored in the local filesystem and loaded by the system kernel at boot time and then shared with various access rights between all processes running on the local system, or loaded and mapped in all processes started in a user session when the user logs on the system. The Old New Thing. Data is stored in. When a machine is moved from one scope to another e. The hierarchy of registry keys can only be accessed from a known root key handle which is anonymous but whose effective value is a constant numeric handle that is mapped to the content of a registry key preloaded by the kernel from a stored "hive", or to the content of a subkey within another root key, or mapped to a registered service or DLL that provides access to its contained subkeys and values. Keys must have a case insensitive name without backslashes.
This “magic application starting thingy” works because of a little-known Windows feature based on the “App Paths” registry key. We recommend registering your application in the App Paths registry subkey.
Doing so avoids the need for applications to modify the system. This was news to me. Basically, not every app has to be on your PATH to be launched via executable name only (from anywhere).

Setting INSTALLDIR from the Registry
When the bit registry was created, so was the additional capability of creating multiple named values per key, and the meanings of the names were somewhat distorted. The terminology is somewhat misleading, as each registry key is similar to an associative arraywhere standard terminology would refer to the name part of each registry value as a "key".
The following table shows other difficulties or limitations caused by using.

To remove a key and all subkeys, values and datathe key name must be preceded by a minus sign "-". Technically, they are predefined handles with known constant values to specific keys that are either maintained in memory, or stored in hive files stored in the local filesystem and loaded by the system kernel at boot time and then shared with various access rights between all processes running on the local system, or loaded and mapped in all processes started in a user session when the user logs on the system.

The Software\Microsoft\Windows\CurrentVersion\App Paths key is mainly used as a %Path% environment variable extension for the shell so it. [Registry] Root: HKLM; Subkey: "SOFTWARE\Microsoft\Windows\CurrentVersion\ App Paths\"; ValueType: string.
Mentioned in points 82 and Because user-based registry settings are loaded from a user-specific path rather than from a read-only system location, the registry allows multiple users to share the same machine, and also allows programs to work for less privileged users.
Even though the registry presents itself as an integrated hierarchical database, branches of the registry are actually stored in a number of disk files called hives. Also, each user profile if profiles are enabled has its own USER.
REG files are compatible with Windows and later. The editor can also directly change the current registry settings of the local computer and if the remote registry service is installed and started on another computer it can also change the registry on that computer. Windows Registry can be edited manually using programs such as RegEdit.

Windows Registry Editor Version 5.
The Windows Logo Program has specific requirements for where different types of user data may be stored, and that the concept of least privilege be followed so that administrator-level access is not required to use an application.
When introduced with Windows 3. It is also possible to use Reg. Archived from the original on
