Preinstalls

Preinstalls, in computing, refer to software, data, and configurations that are installed on a device or system before it is delivered to the end user. This can include the operating system, drivers, utilities, enterprise applications, or content provided by manufacturers, distributors, or service providers. Preinstalls aim to deliver a ready-to-use experience and ensure consistency across devices, but may also raise concerns about privacy, performance, and user choice.

On consumer electronics and mobile devices, preinstalled software often includes manufacturer apps, carrier apps, and trial software. Some of these apps are removable, while others are integral to the device's functionality. In enterprise contexts, devices may be provisioned with corporate configurations, security policies, and licensed software before shipment.

In software packaging, the term preinst can refer to a preinstallation script that runs before a package is installed, updated, or removed. In Debian and related distributions, the preinst script prepares the system, stops services, or migrates data as needed during package operations.

Advantages include faster setup, standardized configurations, and compliance with licensing. Drawbacks include potential privacy issues, increased storage use, and user inconvenience if unwanted software is difficult to remove. Manufacturers and policymakers sometimes encourage reducing preinstalled software and providing clear uninstall paths.
