Registry editors are the primary tool used to manage and analyze the Windows Registry. Registry editors can be used to view and edit registry keys, values, and data as well as to delete or add keys and values from a Registry hive.
The most popular Registry editor for Windows is Regedit. Regedit provides a graphical interface for editing the Registry and includes the ability to find and replace specific text strings, import and export entire Registry entries, delete and rename keys, and copy and paste values between different sections of the Registry.
Another useful tool for managing the Windows Registry is the Registry Editor Utility (REGEDIT.EXE). This utility allows users to remotely edit the Registry, back it up and restore it, set user permissions and security rights, and perform many other functions related to the management and analysis of the Windows Registry.
The Windows Resource Kit also provides a command line program called REG.EXE, which can be used to query, create, delete, and modify keys and values in the Registry, as well as provide detailed reports on all Registry objects.
Finally, there are various third-party Windows Registry management and analysis tools available, such as Registry Workshop, RegEditX, and Registry Mechanic. These tools provide advanced features such as the ability to compare, merge, and repair corrupted or damaged Registry hives, as well as search and replace text strings within Registry keys and values.
