Hello,

Thanks for your response. Unfortunately, windows embedded is not my altiris notification server. Currently, I am using Altiris Notification Server v7.0.7416. Did you know what is the version that already support Windows 7 Embedded ?

Thanks,

Hendardi

It's present in SMP 7.0 SP5.. I can't guess when they added it.  Version is 7.0.8641.  You should consider upgrading to access the new filter.

Here's the resolved query.  I noticed it includes Windows XP Embedded, and win32, so perhaps you'll want to modify the query for your purposes.

SELECT
   [vri1_Computer].[Guid] AS [_ResourceGuid]
FROM
   [vRM_Computer_Item] AS [vri1_Computer]
      INNER JOIN [Inv_AeX_AC_Identification] AS [dca2_AeX AC Identification]
         ON ([vri1_Computer].[Guid] = [dca2_AeX AC Identification].[_ResourceGuid])
      INNER JOIN [vComputerResource] AS [ajs3_vComputerResource]
         ON ([vri1_Computer].[Guid] = [ajs3_vComputerResource].[Guid])
WHERE
   (
      (
         ([ajs3_vComputerResource].[IsManaged] = 1)
         AND
         (
            ([dca2_AeX AC Identification].[System Type] = N'Win32')
            OR
            ([dca2_AeX AC Identification].[System Type] = N'win32')
         )
         AND
         ([dca2_AeX AC Identification].[OS Name] LIKE N'Microsoft Windows XP Embedded')
      )
   )
