How to control Windows system volume using JScript or VBScript?

Question

I want to control the volume of my Windows system from a JScript or VBScript script. Any ideas?

Also, can I unmute the system volume if it is muted?

Misty Manor's Answer Works on Windows Vita as well. This, i literally just made, does the same in a sense.

set oShell = CreateObject("WScript.Shell") 
oShell.run"%SystemRoot%\System32\SndVol.exe" 'Runs The Master Volume App.
WScript.Sleep 1500 'Waits For The Program To Open
oShell.SendKeys("{PGUP}") 'Turns Up The Volume 20, If It Is Muted Then It Will Unmute It
oShell.SendKeys("{PGUP}") 'Turns Up The Volume 20
oShell.SendKeys("{PGUP}") 'Turns Up The Volume 20
oShell.SendKeys("{PGUP}") 'Turns Up The Volume 20
oShell.SendKeys("{PGUP}") 'Turns Up The Volume 20
oShell.SendKeys"%{F4}"  ' ALT F4 To Exit The App.

If you want to decrease the volume you would do

oShell.SendKeys("{PGDN}") 'It Will Decrease The Volume By 20
