If you have a full version XP CD the following should work.
If your XP is OEM (pre-installed) you will need to review your restore options in the manual.
Windows cannot display the volume control on the taskbar because the Volume Control program has not been installed. To install it, use Add/Remove Programs in Control Panel.
You need to copy the sndvol32.exe image from your commercial XP installation media (not a vendor-supplied "recovery" CD-ROM) to the system32 folder by performing the following steps:
1. Start a command session.
2. Navigate to the CD-ROM drive by typing:
<cd drive>:
3. Navigate to the i386 folder by typing:
cd i386
4. Expand the sndvol32.ex_ file by typing:
expand -r sndvol32.ex_ %systemroot%\system32
e.g. If your CD drive is D: type the following: (note the space after sndvol32.ex_)
D:\I386>expand -r sndvol32.ex_ %systemroot%\system32
