MS Security Essentials PowerShell Updater

I have MS Security Essentials (MSSE) installed on my netbook and was looking on bing/google on any scripts/apps that will update it more often and not through Microsoft Update (MU). I stumbled upon: http://social.answers.microsoft.com/Forums/en-US/mseupdate/thread/ef8051c7-b133-4cd5-ab32-ca10d61fe223 and got me thinking on how can I do the same thing a bit better and in powershell-style than command/batch scripting.

Prerequisite:
1) WGET for Windows: http://users.ugent.be/~bpuype/wget/
2) Setting your PowerShell Execution Policy to Unrestricted by:

Set-ExecutionPolicy Unrestricted

or put this into a cmd/batch file:

powershell.exe -ExecutionPolicy unrestricted -file Update-MSSE.ps1

The Actual powershell script, Update-MSSE.ps1:

$arch = (gwmi win32_operatingsystem).osarchitecture
$pth ="D:\" #set to the path where wget.exe is stored
$dwnld = "false"
$lnkID = "0"

if ($arch -eq "32-bit"){
$lnkID = "87342"
$dwnld = "True"
} elseif ($arch -eq "64-bit") {
$lnkID = "87341"
$dwnld = "True"
} else {
echo "Error! OS Architecture not found!"
pause
break
}

if ($dwnld -eq "true"){
Start-Process -wait cmd.exe -ArgumentList ("/c " + $pth + "wget.exe -q -N http://go.microsoft.com/fwlink/?LinkID="+$lnkID)
if ((Test-Path .\mpam-fe.exe) -eq "True") {
Start-Process -wait .\mpam-fe.exe -ArgumentList "-q"
} elseif ((Test-Path .\mpam-fex64.exe) -eq "True") {
Start-Process -wait .\mpam-fex64.exe -ArgumentList "-q"
}
}

and you can automate this by creating a task in task manager to run this script as often as you want.
