Since Win8 the Defender known from Vista/7 has been replaced by MSSE (but named Defender on these newer operating systems). Thus WOU downloads MSSE installation files and signature updates.

it's mean it's normal (no bug) if the Windows Defender Definition Option download : tow MSEInstall.exe files + the mpam-fex64.exe file ?
? Right ?

To my knowledge, the "Windows Defender Definitions" option does not have any effect on Windows 8 or higher. Since the MSSE-Defender of Win8+ is paert of the OS, WSUSOU always downloads MSSE Definitions for these OS.

The original "Windows Defender" is only for Windows Vista and Windows 7.

You should select "Microsoft Security Essentials" to get virus definition updates for Windows 8 and higher. You don't need the installers, but the virus definition files are the same for MSSE as for Windows 8 and higher.

The antivirus software of Windows 8 is sometimes also called "Defender", but if you select "Windows Defender definition updates", it will be changed to "Microsoft Security Essentials" internally, depending on the Windows version.

This is from DownloadUpdates.cmd, as of version 10.0, starting at line 151:

Code: Select all
if /i "%3"=="/includemsse" set INC_MSSE=1
if /i "%3"=="/includewddefs" (
  echo %1 | %SystemRoot%\System32\find.exe /I "w62" >nul 2>&1
  if errorlevel 1 (
    echo %1 | %SystemRoot%\System32\find.exe /I "w63" >nul 2>&1
    if errorlevel 1 (
      echo %1 | %SystemRoot%\System32\find.exe /I "w100" >nul 2>&1
      if errorlevel 1 (set INC_WDDEFS=1) else (set INC_MSSE=1)
    ) else (set INC_MSSE=1)
  )
)


So, it is not a bug, but I find this slightly confusing myself.

Same Same, if i donwload MSSE i don't have the virus base update only : http://i.imgur.com/3bZdP0j.jpg

Then it seem not possible to get only the update virus base like with WSUSOffline

Under Windows Vista and 7: included "Defender" = Windows Defender
Since Windows 8: included "Defender" = MSSE

So wsusou downloads MSSE definitions when running it for Windows 8 or higher ignoring if you select Defender or MSSE. (wsusou treats the "Defender" on Windows 8 or higher as MSSE, so it runs it's MSSE-behaviour)

Ok, for Windows 10 it's mean :
Include Microsoft Security Essentials Option == Include Windows Defender definition Option

Each options provide the same result!
Right?
