How to undo changes made by winrm quickconfig

Here’s what happens when you do a winrm quickconfig:

In my case the Windows Remote Management (WS-Management) service was already running, so its startup type was merely changed to “Automatic (Delayed)”, but if it wasn’t already running then it would have been started too.

So what all happens here?

  1. The service is started and type changed to “Automatic (Delayed)”.
  2. Starting the service in itself does not do anything as it does not listen for anything. So a listener is created. This listener listens for messages sent via HTTP on all IP addresses of the machine.
  3. A firewall exception is created for Windows Remote Management.
  4. A configuration change is made such that when a remote user connects with admin rights to this machine, the admin rights are not stripped via User Account Control (UAC). (See this & this blog post for what this means). Basically, this configuration change involves modifying a registry entry.

Thus, to undo the effect of winrm quickconfig one must undo each of these changes.

1. Disabling the service

Either go via the Services MMC console and (1) stop the service and (2) change its type to disabled; or use PowerShell (running as administrator of course):

That’s disabled.

2. Delete the listener

You can see the listener thus:

And delete it thus:

The command has no output, so enumerate the listeners again if you want to confirm.

3. Delete the firewall exceptions

Either go via the GUI and disable the highlighted rule:

winrm-firewall

Or use PowerShell:

That’s disabled.

4. Disable Remote UAC

Either open the Registry Editor and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System, then set the value of LocalAccountTokenFilterPolicy to 0 (zero).

Or via PowerShell:

That’s it!
