I'm not sure how you change the startup sound in Windows Vista or 2000
Go to control panel, double click on Sounds and Audio Devices, then click on the Sounds tab. Scroll down until you find the "Start Windows", click it, click browse, and then select the sound you want as your startup noise, then click ok
In Windows operating systems, sound effects including the "welcome tune" may be disabled, enabled or changed from the Control Panel. The exact label and location of this function varies with the different versions of the Windows operating system; under Windows 7, it may be found under Appearance and Personalization, then under the sub-heading Personalization, then Change sound effects.In the Sound dialog, the 'welcome tune' can be found under Windows/Windows Logon. The Windows Startup sound can be disabled from the same dialog.
You cannot find any web page where that is exept if you have windows2000
