User:Lucas Brooks/Researches/Windows 1.0 DR5 CONFIG.BIN

During the early days of Windows 1.0, Microsoft used a file named  to store OEM configurations and system bitmaps later stored in the display driver. It existed since Development Release #1 and last appeared in Development Release #5.

Basic Information
DR5's  can be split into 2 sections - the header and the body. The header contains offsets of various resources. The body is made up of 3 sections - the system font definition, the system bitmaps and the icon compression factors. The icon compression factors are never used, hard coded ones are used instead.
