      I found this neat little script which works with manual input.

      But I’d want some changed here.

      First I would like to read from a csv I have (AllComputers.csv). This csv has all 4000+ computers we have here. All listed under the name ‘Computername’ in the csv.

      Next I would love that it’s exported back to another csv with all computers listed and their last logged on user next to it.

      Well, the only change you need here is to take the computernames form CSV file using Import-CSV cmdlet.
      A small example below
      Lets say the header for computer name is Name

      But this is gonna kill you with time when targeting huge number of nodes. You can try using Invoke-Command with -AsJob then Get-CimInstance inside the scriptblock of Invoke-Command

      With 4000 computers, this is going to take a long time.

      There are a ton of resources that show you how to read from a CSV, even in this forum. Get-WMIObject is deprecated, use Get-CimInstance. The logic in the code could use some work.

      • Get all network profiles
      • Sort profiles on lastlogon descending
      • Select the first item with all properties
      • Where the lastlogon matches 14 char digit
      • Loop thru each objects
      • Create a new object with parsed date

      When I test, the date does not require parsing:

      Note that NULL lastlogon date are filtered out in the actual query, so no need for the Where or the for loop or creating another object:
