`dumpbin /dependents` gives similar information. I use the following PowerShell function to get output that's a bit closer to ldd:

  function ldd($ExePath) {
      $Dumpbin = gi "C:\Program Files*\Microsoft Visual Studio\*\*\VC\Tools\MSVC\*\bin\HostX64\x64\dumpbin.exe"
      $Done = $false
      & $Dumpbin /dependents $ExePath
          | ? {$_.StartsWith("  ")}
          | % {$_.Substring(2)}
          | % {if ($Done) {} elseif ($_ -eq "Summary") {$Done = $true} else {$_}}
          | % {if ($_.StartsWith("  ")) {$_.Substring(2)}}
  }

This is really neat. Thank you for sharing.

There is actual the ldd available on Win32, along with gcc, objdump, etc...

It comes with the mingw or msys suite.

Also is there an equivalent to this for Linux?
