Bootsplash

A bootsplash can be a simple visualization of the scrolling boot messages in the console, but it can also present graphics or some combinations of both.

Unlike splash screens, a bootsplash is not necessarily designed for marketing purposes; it can be intended to enhance the experience of the user as eye candy, or provide the user with messages (with an added advantage of color-coding facility) to diagnose the state of the system.

With extra, third-party utilities, it is possible to replace the default Windows boot screen with custom images, text, and/or animations.

In Windows Vista, the default boot screen is represented by a green indeterminate progress indicator.

If the ACPI BGRT table is present, the boot screen will display the OEM logo instead.
