        output = subprocess.Popen(cmd,stdout=subprocess.PIPE,shell=True).communicate()
        try:
            windows_exe = (output[0].split('\r\n')[0].strip().split()[0])
        except:
            windows_exe = None
        try:
            language, codepage = win32api.GetFileVersionInfo(windows_exe, '\\VarFileInfo\\Translation')[0]
            stringFileInfo = u'\\StringFileInfo\\%04X%04X\\%s' % (language, codepage, "FileDescription")
            description = win32api.GetFileVersionInfo(windows_exe, stringFileInfo)
        except:
            description = None

    except:
        description = None

    return description

print get_web_server()

import os
import subprocess
import re
import win32api
pid=subprocess.check_output('netstat.exe -abno | find /i "listening" |find ":80"', shell=True).split('\n', 1)[0].split()[-1]
webserver= subprocess.check_output('tasklist /FI "PID eq '+pid+'" /v /fo List', shell=True).splitlines()[-1].split("Window Title:", 1)[1].rsplit("Window Title:", 1)[0].strip()
def getFileDescription(windows_exe):
    try:
        language, codepage = win32api.GetFileVersionInfo(windows_exe, '\\VarFileInfo\\Translation')[0]
        stringFileInfo = u'\\StringFileInfo\\%04X%04X\\%s' % (language, codepage, "FileDescription")
        description = win32api.GetFileVersionInfo(windows_exe, stringFileInfo)
    except:
        description = "unknown"
    return description
print getFileDescription(webserver)

Output for above is "Apache HTTP Server"

I don't know why your's doesn't work in XP, but try the code above (Python 2.7)

Basically: executes command> gets relevant line> gets last word(PID) in output> passes pid to tasklist> goes to relevant line in tasklist> prints first word.
