Try this:
$Result = @()
Get-Content -Path C:\Temp\test.txt |
	ForEach-Object {
		"Processing $_ ... " | Write-Host -Foregroundcolor White -NoNewline
		$ResultConfig = $Null
		$ResultResync = $Null
		$Output = "Offline"
		If (Test-Connection -ComputerName $_ -Count 2 -Quiet) {
			$Output = & w32tm.exe /config /computer:$_ /update /syncfromflags:domhier
			If ($LASTEXITCODE -eq 0) {
				$ResultConfig = "OK"
				"config OK " | Write-Host -Foregroundcolor Green -NoNewline
				"... " | Write-Host -Foregroundcolor White -NoNewline
				$Output = & w32tm.exe /resync /computer:$_ /rediscover

			$ResultConfig = $Output

		If (($ResultConfig -ne "OK") -Or ($ResultResync -ne "OK")) {

As to the script content: there's no need for registry editing, this can all be done using w32tm.exe.
2.: Not required; if the type is NT5DS (domain hierarchy), the ntp server entry is not used.
4.-5.: Not required with "w32tm /update"
7.: The script will generate a custom object that you can treat however you want, especially using something like
.\Whatever.ps1 | Export-Csv -Path "C:\Temp\w32tm.csv" -NoTypeInformation
