OS/2 Subsystem for NT

HKLM\SOFTWARE\Microsoft\

Description

The OS/2 Subsystem for NT subkey stores basic software information for the Microsoft OS/2 version 1.x subsystem. The OS/2 Subsystem for NT subkey contains several subkeys but, by default, only the config.sys subkey contains an entry. When an OS/2 program has been run on the system, the config.sys subkey contains configuration information for OS/2. Until then, this subkey contains a single entry that serves as a placeholder.
