The pipe "|" does not work in the Windows command console.

Question

This is a very weird problem. I am using 64-bit Windows VISTA command window for very long time and it just suddenly do not work with the pipe character anymore. I have checked the PATH and PATHEXT in Administrator mode and they look OK.
Detail below:
For example, the "dir" work as expected.
C:\newcmd>dir *.txt
 Volume in drive C has no label.
 Volume Serial Number is 4CD2-5B84
 Directory of C:\newcmd

If pipe to a VBScript file below, the error message shows up. The error message is actually the content of %PATHEXT% environment variable:
C:\newcmd>dir *.txt|cscript //nologo cut.vbs -c "1-12"
'.COM;.EXE;.BAT;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC;.REX;.REXG;.REXP;.CMD;'
is not recognized as an internal or external command, operable program or batch file.
The VBScript works fine without the "|":
C:\newcmd>cscript //nologo cut.vbs
Usage:cut "<delimiter>" "<column 0>,<column 1>,..."
Example:cut "|" "0,1,8"
What is going on and how to fix it? Help?
C:\newcmd>echo %PATH%
C:\Windows\system32;C:\Windows\System32\Wbem;C:\Program Files (x86)\CyberLink\Power2Go;C:\Program Files (x86)\Java\jre1.6.0_07\bin;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\QuickTime\QTSystem\;C:\Program Files\nodejs\;C:\Program Files\ooRexx;c:\
C:\newcmd>echo %PATHEXT%
.COM;.EXE;.BAT;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC;.REX;.REXG;.REXP;.CMD;
