Windows Registration Editor (WRE) is a tool to change the Windows registration information. When you install Windows, the installation procedure prompts for a user name and company name. This information is stored and later used as the default for any other installations. Windows does not provide any simple means of changing this other than accessing the registry directly. Windows Registration Editor enables users to change this information from a simple interface. This prevents unnecessary and possible careless changes in the registry. WRE is a freeware program.
