Registry Console Tool (Reg.exe)

This tool enables you to add, change, delete, search, save, restore, and perform other operations on registry entries from the command prompt or a batch file. It can be used on both local and remote computers.

The version of Reg.exe that is included in the Support Tools has been substantially updated. If you are using Reg.exe commands in existing batch files, be sure to check the syntax in your batch file against the new usage.

Caution:

• Do not use a registry editor to edit the registry directly unless you have no alternative. The registry editors bypass the standard safeguards provided by administrative tools. These safeguards prevent you from entering conflicting settings or settings that are likely to degrade performance or damage your system. Editing the registry directly can have serious, unexpected consequences that can prevent the system from starting and require that you reinstall Windows 2000. To configure or customize Windows 2000, use the programs in Control Panel or Microsoft Management Console (MMC) whenever possible.
