HKEY_LOCAL_MACHINE

HKEY_LOCAL_MACHINE (HKLM) is a key part of a Windows computer's registry, which is like a centralized database that stores system and software settings. Think of it as a library that holds important configuration information necessary for the operating system and installed programs to function properly. HKLM contains data shared across all users and includes details about hardware, security, and system components. It helps Windows manage how hardware interacts with software and ensures system stability. Accessing or modifying HKLM should be done carefully, as incorrect changes can affect system performance or stability.
