FileSystemWatcher cmdlet in Powershell not monitoring system32 folder and subfolders - powershell

Question

I noticed that when using PowerShell's FileSystemWatcher cmdlet that it doesnt seem to monitor System32 or it's subfolders in my Windows 7 computer. A script Í have that works just fine when monitoring subfolders of My Documents (i/e "C:\Users\W\Documents\Fichiers PowerShell" is a fplder path that works) but doesn't work when I substitute a folder path in System32 (i/e C:\Windows\System32\Recovery is a path that doesn't work)
Here is the script i'm working with but System32 paths haven't worked in other FileSystemWatcher scripts. Any advice as to a workaround would be appreciated . I must monitor C:\Windows\System32\Recovery. Thank You.
function FileSystemWatcher([string]$log = "C:\Users\W\Documents\Fichiers PowerShell\newfiles.txt",
[string]$folder = "C:\Windows\System32\Recovery",
[string]$filter = "*ps1",
[char]$timeout = 1000
){
$FileSystemWatcher = New-object System.IO.FileSystemWatcher $folder, $filter
Write-Host "Press any key to abort monitoring $folder"
do {
$result = $FileSystemWatcher.WaitForChanged("created", $timeout)
if ($result.TimedOut -eq $false) {
$result.Name |
Out-File $log -Append
Write-Warning ("Detected new file: " + $result.name)
$filename = (gc $log -ea 0)
ii "C:\Program Files (x86)\Mozilla Firefox\firefox.exe"
remove-item "C:\Users\W\Documents\Fichiers PowerShell\newfiles.txt"
}
} until ( [System.Console]::KeyAvailable )
Write-Host "Monitoring aborted."
Invoke-Item $log}

Give this a try:
$fsw = New-Object System.IO.FileSystemWatcher C:\Windows\System32 -Property #{
IncludeSubdirectories = $true
NotifyFilter = [System.IO.NotifyFilters]::DirectoryName
}
$event = Register-ObjectEvent $fsw Created -SourceIdentifier DirectoryCreated -Action {
Write-Host "$($event.SourceArgs | fl * | Out-String)"
}
md C:\Windows\System32\temp2
