All-in-One PC Windows System: disabled system service. A required background service does not start or loses its dependencies.

The distinguishing clue

Controls vanish even though the device and driver are present.

Checks before an assessment

Note whether the built-in display, camera and audio fail together or whether Windows itself stops loading. Remove only nonessential external accessories with the computer shut down.

Stop point: All-in-one hardware can contain mains-power sections, so software diagnosis should precede opening.

Workshop confirmation and repair

Device-level check: Compare firmware, recovery, another account and external peripherals before opening the display housing.

Targeted check: Check service state, dependencies and event logs rather than reinstalling everything. If confirmed: Repair the service configuration and the cause that disabled it.

Repair boundary: Repair the confirmed software layer after internal hardware and storage checks agree.

Related cause to rule out

When the subsystem is detected but behaves differently for one user or startup mode, also consider All-in-One PC Windows System: corrupted configuration before choosing a repair.

Checks after the work

After repair or replacement, check startup, display, camera, audio, updates, sleep and shutdown.
