A computer with cached pre-assembled device configurations for a faster and more reliable user experience. Pre-assembled device configurations may be obtained in a variety of ways, for example, by pre-processing installation information obtained from driver packages, or by being retrieved from a suitable source. Pre-processing driver packages may involve, for example, copying binary files to their run-time locations and computing settings for the device and driver. The pre-processed device configuration settings may be cached and indexed in a database. When a device connects to the computer, a cached device configuration may be applied to the device without performing a full installation process. Pre-assembly of device configurations may be performed before a device first connects to the computer, for example, upon detecting an applicable driver or during manufacture of the computer, and is not restricted to being performed on the same computer on which the device configuration will be used.
