Windows HotStart in the Windows Vista and Windows 7 operating systems provides built-in support for launching applications directly from system startup. Windows HotStart takes advantage of existing support in Windows Vista and Windows 7 for OnNow power management initiatives and technologies, including the platform sleep states and wake capabilities that are defined by the ACPI specification and supported by the Windows Driver Model (WDM), the underlying operating system, and platform hardware.

Manufacturers can take advantage of Windows HotStart to add consumer-friendly application-access buttons through chassis front panels or infrared (IR) remote controls to their system designs. A common example of such a control is a media playback button that starts or wakes the computer and immediately (as soon as the system is running) presents the user with a media player or dedicated media shell.

This paper describes how to enable and configure Windows Hotstart, troubleshoot Windows HotStart implementations, and use Windows HotStart for Microsoft media applications.

This information applies to the following operating systems:
Windows 7
Windows Vista
