Two important branches:

1. User's personal data [HKEY_CURRENT_USER]

This branch stores personal data such as personal preferences for the current logged-on user, settings for the software used, and so on. You can modify registry data that is personal to you, whether you are a guest, a limited user, an advanced user, or an administrator. The user's personal registry data is the items, subkeys, and value entries contained in the left pane of Registry Editor [HKEY_CURRENT_USER].

2. Core data of the system [HKEY_LOCAL_MACHINE]

Only users with administrator privileges can access the system registry data, which stores the important core settings data in the system. The registry data for the system is the items, subkeys, and value entries that are contained in [HKEY_LOCAL_MACHINE] that are displayed in the left pane of Registry Editor.
