Greetings,

 

I know you can integrates updates in WinToolkit with msu files (official updates for download) or cab files (extracted from msu files).

But there are also express cab files. You can find them in Windows\SoftwareDistribution\Download once you installed updates via Windows Update.

 

Example

windows6.1-kb2533552-x64.cab          size 9   MB

windows6.1-kb2533552-x64-express.cab  size 0,6 MB

 

I extracted both cab files and compared it. There are same filenames, but with different size. windows6.1-kb2533552-x64.cab also contains additional files named 1 to 75 without file extension.

 

 

WinToolkit accepts both types of these cab files. So are there differences regarding the integration and the resulting windows image?

express cab contains only the update manifest files + xml file.. those are used by WU to identify the original package contents and to determine what components of it are needed for the system so it download them only

 

i.e.

if the update are multilingual, it will download only lang resources matching your system

 

only WU knows how to handle this mechanism

so, express cab are useless and cannot be used for integration

      [SendTo] InstallShield Cabinet-Log File Viewer
      By ricktendo
      Here is something you guys might find useful, Its a must have if you are into driverpack making and it comes with InstallShield (used to extract drivers/files from installers with data1.cab/hdr packages created with InstallShield)
      Here is my SendTo style installer, I extracted the files from InstallShield 2018 SP1 (may also require Visual C++ Runtimes)

      cab addon maker type programs for windows 7 - where to find
      By BusyElf
      After some time spent writing cab addon for larger number of files, i started to look for programs that automate most if not all tasks.
       
      I found out there are :
       
      Inf-Addon Maker - haven't found valid DL links (both here and at win-lite)
       
      DX Universal UpdatePack/Addon Creator (filename DXUPAC.exe DXTool_x64_005FE78D48FC1B11F7068FBBE6FC368A.exe) - DL links present but no options found to select Windows 7. Also at start program requires exe of hotfix/update (which i assumed this program creates as CAB output at end, not requires as input at start)
       
      Inf-Assistant - no valid DL links
       
      Are there any usable Win7 INF addon cab makers then ?
       
      EDIT: I downloaded DXUPAC.exe and it was staring in my face the whole time  :doh:  It is split into several "send to" targets so i did not it see as one single package to work with. Which reminds me : do these pieces of DXUPAC have source code somewhere ?
      I kind of like using Notepad2 and manually assembling the INF files.

      copying multiple versions with same file name to multiple target folders
      By BusyElf
      I would like to add nircmd via true addon CAB (a great little utility by Nir Sofer) to my Win7 x64 offline image (ie for making ISO out of it later).
       
      It has both x86 and x64 versions.
       
      SInce i intend to use it on x64 Windows, it means that calling application (usually cmd.exe) will call the corresponding version of nircmd (x86 cmd calls x86 nircmd and respectively x64 cmd.exe calls x64 version of nircmd).
       
      Now a problem : i can make a CAB file that holds both versions under different names in same folder inside CAB, but since in future i intend to add other dual-bitness applications, this will be a problem for me.
       
      I have my CAB referenced in Entries.ini like so
      [txtsetup_files]AddUtils.cab = 1,,,,,,_x,,3,3Note that i have left out other relevant information to make this post short and to the point.
       
      I would like to package both versions of nircmd in CAB file under different subdirectories, like so :
      MYCABFILE.CAB   < CAB file itself\X86VER\nircmd.exe  < first version in subdirectory\X64VER\nircmd.exe < second version in other subdirectoryI was reading INF reference documentation on MS site and it mentions multiple directories, but it is unclear to me if the above is possible.   There are two descriptions that don't explain this well enough :
      [SourceDisksNames]diskid = disk-description[,[tag-or-cab-file],[unused],[path],[flags][,tag-file]]I don't know if "path" part refers to my above case of subdirectories in CAB file or some other location.
       
      Second one is
      [SourceDisksFiles]filename=diskid[,[ subdir][,size]]Also, i'm not sure to what "subdir" points to.
       
       
      I was trying to find other true addons as examples (so far, they have been useful), and closest one is for Notepad2, similar to what i need, but it either copies x86 or x64 version (as defined in section names), and i need BOTH versions of nircmd.exe to be copied in their respective directories (%SystemRoot%\System32 and %SystemRoot%\SysWOW64).
       
      I hope i haven't overcomplicated my post, i just wanted to be as specific as possible.

      Exclude *-express.cab from integration
      By Shodan2000
      Hello Legolash2o,
       
      first thanks a lot for this great and powerful tool.
       
      I have a request to exclude *-express.cab (see this thread) from selection, since according to the forum member abbodi1406 they cannot be integrated.
      Still they can be selected in WinToolkit and novice users like myself surely don't know that these cab files are useless for integration.
       
      So far I encountered cab file dialogs here:
      Main menu->Tools->Misc->Update Retriever Tab Basic->All-in-one Integrator->tab Updates + Languages

      Definition Update for Microsoft Security Essentials
      By eveafterdark
      Hello everyone,
       
      maybe someone has been through that and has knowledge to share
       
      is there a .cab file for mseinstall.exe (microsoft security essentials)  so that I could add it to an offline  image using dism ?
      I did some searching but found none, so I guess there's no .cab or msu for it ... ?
       
      the other thing - I suppose I could add  the .exe to silent installers (with WinToolKit) but then I was wondering -  is it possible to add Definition Update for Microsoft Security Essentials KB2310138 (Definition 1.165.1048.0) ?

      it is the package windows wants to download for ms security essentials after a fresh install and of course I wouldn't like to download it everytime I make a fresh install.

      By "add" I mean add it to an offline image with dism, the same way I add e.g. IE11 or prerequsities for IE11. (the way I create my images is I first do things I can do using command line and for the rest I go for wintoolkit)
      First thought is it does not make any sense to add updates (virus def) while there is no program installed yet that could use these definitions.

      But let's say I did that, and then I go to Wintoolkit and add mse.exe (silent installer). Will it work ? I mean will the antivirus program use these definitions and updates itself without downloading them?

      I'll try to do that myself but if anyone tried this before, I'll be glad to hear some feedback
      Cheers,
      eveafterdark
