Query and sign off disconnected users (Win10)

Recommended Posts

So I have no example code currently because I'm not sure where to even start.

We're using the parental controls on the computer and the kids each have their own user profiles with limited time. The problem we're encountering is when their time runs out, or if they just hit Win+L and leave the computer, their games are still running in the background. I was hoping to write up a quick AutoIt script and throw it in a recurring scheduled task to just sign off any of the kid's profiles that's not currently active. I found some suggestions to use "query session" and then "logoff [user]" in the command line (which it seems I could easily automate with AutoIt) but that's only available on Win Pro and this system is running Home (and I even tried copying the query.exe from a Pro system but it errors out). Is there some AutoIt equivalent to the query and logoff functions or am I stuck?

Edit: I'm adding some clarification to exactly what I'm hoping to get out of this script.

I'd like to setup a scheduled task that runs outside of the current user (perhaps under the SYSTEM account?) in case NO user is currently active, that will detect which users are currently signed in. If users from a predefined list are not currently active, sign them off entirely.

So let me give two examples:

Example #1:

- I am logged in, but not active (I left my browser open and locked the computer)
- Nephew A is logged in, but not active (his time ran out while his game was running and the computer auto-locked)
- Nephew B is logged in, and currently playing a game

When script runs, ignore my profile (leave it signed in), log out Nephew A (closing his game), and ignore Nephew B because he's actively using the computer.

Example #2:

- I am logged in
- Nephew A is logged in
- Nephew B is logged in
- No users are currently active (Windows is sitting on the choose user / sign in screen)

When script runs, ignore my profile, log out Nephew A and Nephew B.

 

I would perceive pseudo code, going as such:

$aChildUsers = [ 'NephewA', 'NephewB' ]

$aUserList = GetSignedInUsers()

For $i = 0 to UBound($aUserList)-1
    If Not UserIsActive($aUserList[$i]) Then
        For $j = 0 to UBound($aChildUsers)-1
            If $aUserList[$i] = $aChildUsers[$j] Then LogOffUser($aUserList[$i])
        Next
    EndIf
Next

Obviously, GetSignedInUsers(), UserIsActive(), LogOffUser() are not real functions. What I'm searching for is something of their equivalent.

Thanks for your time!

Didn't have spare time to build an example, but you can definitely have a look at PsLoggedOn from SysInternals suite.
Just execute the command, get the result, and use the logoff command with the specified users.
Hope it helps.

Cheers ^_^

I am assuming that there is only one user for that computer at a time.  Here how I would do it :

1- Get list of users with WMI Win32_LoggedOnUser

2- Get _Timer_GetIdleTime()

3- if Idle Time > xy minutes and User is a child then ShutDown ($SD_REBOOT+$SD_FORCE)

If that makes sense and need help to convert this pseudo-code into real code, let me know...

Well PsLoggedOn is promising. However I'm not sure how to tell who the currently active user is (assuming I can get this to run from the SYSTEM account or somesuch), or how to log off other users (the logoff command doesn't seem to be available on Home either).

Well there's only ever one active user, but often my brother or I will be logged on but disconnected. For example. In this example, I only want to sign out the user at the top.

So I'm having some issues with your implementation:

  • Win32_LoggedOnUser seems to list every user, logged on or not.
  • How would I get the idle time (_Timer_GetIdleTime) for each user?
  • How do I use Shutdown on another user? (Also wouldn't I just want $SD_LOGOFF+$SD_FORCE, because I don't want to restart the whole computer).

Thanks for the input so far though guys. 

I'm going to edit my top post to clarify what I'm looking for.

I see.  Everybody leaves the computer but stay on. Maybe a change of habit would be recommended.  If you want to supervise your children,  my approach is flawless.  But if you want to preserve your habits, good luck then.

The issue with just shutting off the computer is sometimes we access it from other computers when we are not at home.

Well I figured out a method. Not quite the way I intended, but isn't that usually the way of AutoIt? 😁

So, I created this little script:

If $CmdLine[0] Then
   For $i = 1 to $CmdLine[0]
      If @UserName = $CmdLine[$i] Then
         If Not Shutdown(4) Then MsgBox(0x10, @ScriptName & ' - Error', 'There was an error (#' & @error & ') trying to log off this user: ' & @UserName)
      EndIf
   Next
Else
   MsgBox(0x40, @ScriptName, 'Will force log off if current user matches any name given as command parameters' &@CRLF&@CRLF& 'ie:    ' & @ScriptName & ' "Aaron" "Bob Smith"' &@CRLF&@CRLF& 'Will log off Aaron or Bob Smith')
EndIf

And then I created a Scheduled Task triggered to run "On workstation lock of any user", gave it parameters of the kids' usernames, and Bob's your uncle.

In my brief testing it seems to work alright.

      Hi,
      I started this project alone in May 2020 as project in my spare time at work, I'm working for a IT company that started opening their services to residential customers few months ago and now my position in the company kinda drifted in the doom and gloom world of repetitive tasks like: Reinstallation of Windows 10.
      The procedure is very repetitive and I started feeling like being a robot which is the main reason I started this project.
       
      ==============================FAQ==================================
      1. Q: Do you want this project to be accomplished with the usage of AutoIT ONLY or 3rd party tools / Scripts (BATCH / POWERSHELL / VB) ? A: No, if I cannot find a way using AutoIT to accomplish a task I will move to my Plan B which consist of automating an 3rd party tool to accomplish the affected task until a solution is found. 2. Q: What do I get from helping/collaborating in this project? A: I will personally take the responsability to mention you in the credits of this project. 3. Q: If I have more questions, can I ask? A: Certainly! feel free to ask any questions related to this project! 4. Q: What is the main goal of this project? A: Automating Windows 10 configuration without user interaction needed (as much as possible) ______________________________________________________________________________________________________________________________
      Current progression of the project (more will be added in future)

      I use SetSoundDevice to control my audio devices but the UI was either
       
      blurry like this:
      or unusable like this:

      so I made this horrible thing to add scaling to the GUI:

      And now it looks good: 
      but it doesn't work on everything, for example the "GUICtrlCreateLabel("Output type: ", 30, 130, 65, 20) ;, $SS_RIGHT)" (from the autoit3wrapper gui)
      because the comment contains a parenthesis and it would break completely if there were variables as parameters..
      Is there some kind of parser around that I could use instead or maybe someone who has already done something like this?

      Hello!!!  
      In the past I had problems adding an application as a default for an extension in Windows 10. (It was easy in windows 7 using Registry) But since Windows 8 It requires to do some steps more. I wrote a tool (in other programming language) months ago for handling it. But now I just want to share an AutoIt version.

      Dan - thanks for all that you do - this stuff is great. 
      Hoping you can assist with an issue we are having now that we have moved to Windows 10/Server 2016. The Chrome interactions were working flawlessly until moving over. Now my code fails when attempting to create the session. As you can see, our Chrome install is not in a standard location but I have validated the path to the binary. I have attached some detail below including system info, console output and the chrome log detail. I have tried several recommendations that have seen in various forums but none have made a difference
      Any assistance you can give would be greatly appreciated. 
      Thanks in advance,

      Hello everyone.
      I always try to work with old Windows 10 versions as much as possible because I know mane compatibility issues with Windows 10 upgrading. 
      But I couldn't do anything else (I got drivers problem), and nothing couldn't help me besides upgrading, so I upgraded from 1807 to 1903.
      And...get another problem 😃
      I use AutoitX library in external project like this.
      ObjectAutoIt=New COMObject("AutoItX3.Control");
      ObjectAutoIt.AutoItSetOption("WinTextMatchMode",2);
              While ObjectAutoit.WinExists("",WindowHeader) Cycle 
                  ObjectAutoIt.WinClose("",WindowHeader);
              EndCycle;
      After upgrade I get that this line code 
      While ObjectAutoit.WinExists("",WindowHeader)
      become extremely low - ~ 20 seconds even if 10 windows open. But before upgrade it takes 0.5 s for a max.
      And every time that this code line passes through  - it takes ~20s, (20.115, for example), not less, not more. Something pauses it to work.
      How can I diagnose, what is that?
      I tried reinstall whole AutoIt, but no results.
      Thanks to all.
