Release 10.1A: OpenEdge Deployment:
Managing 4GL Applications

> ## Maintaining the Windows user environment

> In the Windows software environment, OpenEdge uses the `progress.ini` file as well as the Registry to maintain environment variables.

> When you install OpenEdge, the installation program automatically updates the Registry with the information in the `progress.ini` file that is shipped to you. Progress Software recommends that you maintain environment variables in both the `progress.ini` file and the Registry. If you modify environment variables in the `progress.ini` file, you must update the information in the Registry.

> Although there are several methods for adding and deleting information from the Registry directly, Progress Software recommends that you do not use these direct update methods. Instead, maintain the Registry information by editing the `progress.ini` file and using the INI2REG utility to update the Registry. This approach synchronizes the information in the `progress.ini` file and the Registry without causing unintended edits to the Registry.

> For more information about modifying the `progress.ini` file, see the "Maintaining the progress.ini file" section.

> In addition to the `progress.ini` file, the OpenEdge installation includes a Windows manifest file which provides your 4GL application with the Windows XP look. For more information on this file, see "The Windows manifest file" section.
