For the record this is for V1. I have an existing script that works (aside from stopping Telephony and Remote Access Communication manager). After getting a working version which does a gwmi query foreach of the 27 services in the array the gc creates I went back and said okay lets do an all inclusive win32_service query and then process each of the returned services and if the returned .Caption equals one of the array elements perform the set of actions to stop and disable the service......

-match will take the value on the left and see if it matches the regular expression on the right. If the strings contained in $defsvcs can be used as regular expressions, then you can do something like this:

foreach ($svc in $actsvcs){
foreach ($match in $defsvcs) {
if ($svc.Caption -match $defsvcs){
"Found " + $svc.Caption
}
}
}

or if $defsvcs is a list of the actual names as opposed to an expression to match, you can use -contains like this:

foreach ($svc in $actsvcs){
if ($defsvcs -contains $svc.Caption){
"Found " + $svc.Caption
}
}

Ugggh so I had the comparison (-contains) backwards... ugggh. The array is a list of the known Captions (i.e. Telephony) so the contains is easy enough. Thanks alot!

Is there a way to replicate this when comparing columns in an Excel spreedsheet or csv file. Like diffing what exist and exist on sheets being compared.
