Windows Users like “Window Manager\DWM-3” are virtual users
Posted by jpluimers on 2021/03/15
Having seen logon failures from user Window Manager\DWM-3
while on a public WiFi network, I did a quick search on [WayBack] “Window Manager\DWM-3” – Google Search.
It appeared somebody trying a dictionary attack on the RDP port of my Windows VM which was on the host Bridged Network (see [Archive.is] Help – VMware Fusion 6 Documentation Center).
This is a virtual user that is part of a series of users that the Desktop Window Manager started using from Windows 8 and up.
The first user always exist, DWM-2 and up are created for new dwm.exe
processes (by winlogon.exe
) when users start logging on through RDP connections to a Windows machine:
Window Manager\DWM-1
Window Manager\DWM-2
Window Manager\DWM-3
Window Manager\DWM-4
In addition to logging on as a new user, as of Windows 8, these also are created when shutting down and starting up (which Windows fools you by actually doing a kind of hibernate): [Wayback] windows 8 – What is winlogon.exe -SpecialSession? – Super User
