Windows 11 Boot Gif -

Windows 11 does not accept .GIF files for its boot sequence. Boot graphics are compiled into a signed DLL. Replacing them with animated frames is possible but requires disabling security features and may fail after OS updates.

Use a static boot logo replacement (via HackBGRT) and add a “welcome GIF” after login (via Task Scheduler) for risk-free branding. windows 11 boot gif
