The send Control-Alt-Delete command is not working

Reported by katherin...@gmail.com, Sep 12 2017

Issue description

UserAgent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36

Steps to reproduce the problem:
1. Attempt to send Control Alt Delete command from Android Nougat
2. Attempt to send Control Alt Delete command from MacBook Air
3. Different user attempt to send Control Alt Delete command from Chromebook to different PC

What is the expected behavior?
The Control Alt Delete command usually performs the control alt delete keystrokes on the computer we're attempting to unlock.

What went wrong?
Nothing happens when you send the command.  The PCs we're attempting to access do not respond.

Did this work before? Yes I'm not sure

Chrome version: 60.0.3112.113  Channel: n/a
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)
Flash Version: 

Affecting multiple users on latest version of Chrome.

Tested the issue on reported version 60.0.3112.113,latest stable 61.0.3163.79 and latest canary 63.0.3213.0 using Ubuntu 14.04,Windows 10 and Windows 7 and is not reproducible with below steps.

1.Logged into System >> Used Ctrl+alt+del to lock the screen 
2.Able to lock the system

@Reporter: Could you please confirm reported issue is related to windows or other OS Platforms? Could you please restart the machine and check whether issue persists or not?
I'm not sure that I reported my issue to the correct forum.  The issue is
not with Chrome, or Chromebooks.  It is with the Chrome Remote Desktop
application.  The application is loaded on multiple different Windows 7
PCs.  When attempting to Remote Control the Windows 7 PC, sending the
Control Alt Delete command does not execute the command on the PC.  We have
restarted the PCs.  We have tried sending the command from an Android
Nougat phone OS, from a Chromebook and from a Macbook Air.

AJ, can you try to repro? It works fine to my Linux host, so I don't think it's a client-side problem and I don't have a Windows host to test on.

Jamie, I was unable to reproduce this issue with either Windows 7 or Windows 10. The M61 release host and client were installed on both machines. ctrl alt del works as expected.
Thank you for testing.  I didn’t see any other reports of this issue other than the reference back to 2012.  It must be something specific to our environment.

There is a policy you can configure to disallow fake Ctrl+Alt+Del. You can find details at https://msdn.microsoft.com/en-us/library/windows/desktop/dd979761(v=vs.85).aspx. If that policy is configured to prevent it, then I would expect the behaviour you're seeing, and the only fix is to unset the policy.

Since it doesn't appear to be a bug in Chrome Remote Desktop, I'm going to close this for now.
