Glossary Entry: Compatibility Mode

Quick Definition

Software is often designed for a specific version of an operating system*. Newer versions of that operating system* may have changed some important behavior the software requires, and to keep older programs running smoothly the operating system* can try to behave like the older version. This change in behavior is called a compatibility mode, as it's a different mode that tries to be compatible with previous designs.

Unfortunately, this doesn't always work, and switching into the compatibility mode may cause other running programs to malfunction.
