- HKEY_LOCAL_MACHINE (HKLM): This hive holds the configuration settings for the native laptop, no matter who’s logged in. This consists of {hardware} settings, software program installations, and system-wide settings. That is the place the core working system configuration resides.
- HKEY_USERS (HKU): This hive comprises settings for all customers who’ve ever logged into the system, with every person having their very own subkey.
- HKEY_CURRENT_CONFIG (HKCC): This can be a dynamic view of the settings inside HKEY_LOCAL_MACHINE which can be relevant to the present {hardware} profile. It is basically a shortcut.
When the Basis Crumbles: Penalties of Lacking Entries
The lack of registry entries is a critical concern. If the registry is a constructing’s basis, then these are the lacking bricks that may lead all the construction to break down. Relying on which entries are affected, the ensuing issues may be wide-ranging and probably catastrophic.
