Three Ways to List Named Pipes in Windows

Powershell

In Windows, device driver that implements Names Pipes is actually a file system driver (NPFS.SYS). That means you can just list pipes from C# or Powershell which can use .NET calls:

[System.IO.Directory]::GetFiles("\\.\\pipe\\")

output:

\\.\\pipe\\InitShutdown
\\.\\pipe\\lsass
\\.\\pipe\\ntsvcs
\\.\\pipe\\scerpc
\\.\\pipe\\Winsock2\CatalogChangeListener-414-0
\\.\\pipe\\epmapper
\\.\\pipe\\Winsock2\CatalogChangeListener-578-0
\\.\\pipe\\Winsock2\CatalogChangeListener-1cc-0
\\.\\pipe\\Winsock2\CatalogChangeListener-5a4-0
\\.\\pipe\\LSM_API_service
\\.\\pipe\\eventlog
\\.\\pipe\\Winsock2\CatalogChangeListener-c18-0
\\.\\pipe\\atsvc
\\.\\pipe\\Winsock2\CatalogChangeListener-d70-0
\\.\\pipe\\WiFiNetworkManagerTask
\\.\\pipe\\spoolss
\\.\\pipe\\Winsock2\CatalogChangeListener-12d4-0
\\.\\pipe\\wkssvc
\\.\\pipe\\trkwks
\\.\\pipe\\srvsvc
\\.\\pipe\\Winsock2\CatalogChangeListener-2b4-0
\\.\\pipe\\NvWksServiceDdisplayPipe

Sysinternals PipeList

Sysinternals PipeList does similar thing if you already have it installed:

pipelist.exe

output:

Sysinternals Process Explorer

It can also be achieved from Process Explorer. Go to Find -> Find Handle or DLL..

Search for string \Device\NamedPipe. The advantage here is that after search is complete you can visually jump to processes and other objects offered by this great program.
