Hi, To change the Orbit Glowing Animation & sound at Vista Startup open 'authui.dll' with resource hacker. Goto Image ->17000,..01,..02.... Select one of them (i.e. Image->17000->1033) and goto Action -> Save Resources as binary file. In the save dialog give xyz.png(u can u use any name). Noe do same for all following 5 images. Now see they r just the 5 images of that animation. Edit them , Replace with RH. And lastly replace the file... And u r done. To change the startup sound open imageres.dll and goto wav->5051->1033. To replace the wave goto Action -> Replace other resources. In the dialog open the .wav file & fill up as following Resource Type : WAVE, Resource Name : 5051 and Language : 1033. Now save and replace the file. own.zip U r done!!!! Happy hacking!!!!
