The attached StarTrekStartUp cab file is for SPRINT only. If you have another carrier use the files that are included in the zip attachment.
I know there is a reg edit to add the start up animation and sound, but unfortunately this does not kill the Phoneon.wav (for Sprint). So the cab file is for Sprint only as it overwrites the Sprint specific files. If you have another carrier use the files in the attached zip. Rename them as needed and swap them in the Windows directory with Resco or any other app that will overwrite the files. If anyone using a different carrier would be kind enough to cab up the files and post them that would be neato.
These files are large, so if you are pressed for space you might not want to install them. The animated gif is over 3mb. It's from the opening of the original series. I pieced together several clips of the enterprise flying around the orange planet. The start up sound is the beginning of the original opening theme. The Windows splash screen is pictured below.
-- Update 11/2 -- The StarTrekWall6.5 cab is for those of you running WM 6.5. It has the transparent top and bottom task bars. The background was made with HDWall, so there is no need for the background on all tabs cab. You should uninstall it if you are already using it.
-- Update 11/2 -- The StarTrekKBSlidingSounds cab will add two more sound options when you slide open and close your keyboard. One consists of computer sounds and the other is the famous sliding door sound.
