Windows 2000 Registry
Windows 2000 stores its configuration information in a database called the registry. The registry contains profiles for each user of the computer and information about system hardware, installed programs, and property settings. Windows 2000 continually references this information during its operation.

Registry editors are available that enable you to inspect and modify the registry. However, you should not need to do so. Instead, allow Windows 2000 programs to modify the system registry as needed. It is strongly recommended that you do not edit registry settings yourself.

Warning

Incorrectly editing the registry may severely damage your system. At the very least, you should back up any valued data on the computer before making changes to the registry.
If you do damage your system, you may be able to repair the registry or restore it to the same version you were using when you last successfully started your computer. Otherwise, you must reinstall Windows 2000. When you reinstall your system, you may lose any changes that have been made, such as Service Pack upgrades, which you must reinstall separately

Note

Choosing Last Known Good Configuration provides a way to recover from problems such as a newly added driver that may be incorrect for your hardware. It does not solve problems caused by corrupted or missing drivers or files.
When you choose Last Known Good Configuration, Windows 2000 restores information in registry key HKLM\System\CurrentControlSet only. Any changes you have made in other registry keys remain.
