Hi ManelR,
Actually it is not simply to identify correct Product using XML files from PMImport.cab. Affected products are associated with updates, not bulletins, and it is hard to track all associations between different XML files and guids.
MS12-056 includes 6 updates and each update has own affected products.
So in order to try to identify correct product for MS12-056 bulletin, you need firstly to find update you want to distribute from this bulletin.
For example, MS12-056 includes updates IE8-WindowsServer2003.WindowsXP-KB2706045-x64-ENU.exe (http://www.microsoft.com/en-us/download/details.aspx?id=30510)
From file name you may suppose that you should select Internet Explorer 8 (x64).
I have checked on my side that IE8-WindowsServer2003.WindowsXP-KB2706045-x64-ENU.exe and IE8-Windows6.0-KB2706045-x64.msu are indeed imported if Internet Explorer 8 (x64) is selected.
Please find information about remaining updates from MS12-056 below.
