Question

I have the following code where I look up a users SID and if its not found I set an output value to the SID not being found. I output the entire results to a csv file using a psobject.
Whats happening is that I find an invalid sid and instead of stopping processing the user after doing the following:
$objPrintdata.User_SID_Status ="Invalid SID", it continues to process the same sid and goes to the $regPrinterDetails.GetSubKeyNames() |ForEach-Object line where it fails and writes another line with the same SID but with the correct error of registry cant be opened and 2003 cant be found. How can I get out of the loop for the user where I haven't found a SID?

Answer 1

if I understand correctly you want to stop processing the current child key if you have found an invalid SID. If so just add a return statement after the following line:
$objPrintdata | Export-Csv P:\powershell\jv\results.csv -NoTypeInformation -Append
