PnP
Definition
Plug and Play, the Windows device discovery and package-selection architecture.
Detailed explanation
PnP means Plug and Play, the Windows architecture for discovering devices, assigning resources, ranking packages, constructing driver stacks, and managing arrival or removal. Bus drivers report identities and compatible IDs, while INF packages declare supported models. PnP selection is deterministic metadata processing rather than simple name matching. A bus enumerator creates a devnode, Windows ranks matching INF models, and function plus optional filter drivers form the active stack. Device instance state, container identity, parent relationships, and resource assignments persist beyond a single connection, allowing Windows to recognize returning hardware.
Where you are likely to see it
This term usually appears in Device Manager, Windows recovery tools, Event Viewer, or the installation details for a device package. The definition above gives the short meaning; the detailed explanation describes the term's role in the operating system and hardware stack.
Device status, hardware IDs, and event text identify which Windows subsystem produced a label. This glossary is informational and does not provide repair, installation, or technical-support services.
