Registry

Last Updated May 24, 2021 1:53 pm

A database used by the Windows operating system (Windows 95 and NT ) to store configurationinformation. The Registry consists of the following major sections:

HKEY_Classes_Root – file associations and OLEinformation

HKEY_Current_User – all preferences set for current user

HKEY_User – all the current user information for each user of the system

HKEY_Local_Machine – settings for hardware, operating system, and installed applications

HKEY_Current_Configuration – settings for the display and printers

HKEY_Dyn_Data – performance data

Most Windows applications write data to the Registry, at least during installation. You can edit the Registry directly by using the Registry Editor (regedit.exe) provided with the operating system. However, you must take great care because errors in the Registry could disable your computer.
