From Coder For Life:
Modifies the boot animation, colors, text, and background. Modifies the resume from hibernation screen as well. Will create the animation from 105 BMP, PNG, GIF, or TIFF images or use a single (non-animated) image.
Does not require any other applications (like ImageX). Designed to be idiot-proof by having numerous checks. Automatically backs-up the modified files. Does not require test-signing or no-integrity-checks to be enabled. Works for all versions of Windows 7: any language, any edition, 32-bit or 64-bit, RTM or SP1. Available in English, German, Spanish, Russian, Italian, French, Dutch, Hungarian, Hebrew, and Vietnamese. Works even if your setup has the hidden “System Reserved” partition. Can be run as a GUI, command-line program, or installer/uninstaller.
