Windows NT Setup automatically creates the Main, Accessories, Administrative Tools, Games, and Startup groups in Program Manager. To have Windows NT create a new Program Manager group you need to modify the PARTIAL.INF file.
For example, the Terra Flora administrator creates a new program group called TerraFlora in which the TERRA.HLP file, Terra Flora Help, will be included. To do this, the administrator adds lines to the [ProgmanGroups] and [ProgmanGroupsDescriptionENG] sections of the PARTIAL.INF file. In the following example, the new lines are shown at the bottom of each section:
[ProgmanGroups] Main Accessories AdminTools Games Startup TerraFlora [ProgmanGroupsDescriptionENG] Main = "Main" Accessories = "Accessories" Games = "Games" Startup = "Startup" AdminTools = "Administrative Tools" TerraFlora = "Terra Flora Help"
