Question on applying WSUS Offline - to integrated installer

[Sonicmojo]

Hello,

I have a question about using WSUS Offline AFTER I have installed Windows 7 SP1 using an intergrated/slipstreamed install source.

Using Win Toolkit 1.5 - I built an up to date Win 7 iso that contains 195 updates baked right into the install.wim file.

If I install with this iso and then use WSUS Offline after the install - will WSUS realize that 195 patches are already in place and ignore them - and only install "what's left" - like .Net installers etc? Or will it try and blast in all the fixes it current has in my "usb" folder than I created a day or two ago?

Ideally I want to be able to install Win7 with my iso, run WSUS to fill in any last minute items and then run WIndows Update to see if I have nothing "key" left to install.

Appreciate any thoughts.

Sonic.

Simple answer: WSUSOU will ask the Operating System what's missing and what's not. If the Windows Update Agent itself does acknowledge the presence of the slipstreamed patches, WSOSOU won't try to install them. Unfortunately the whole update system is a mess.
Do a test: Does Windows Update display the already included Update KBs in its list?

As far as I know, Win Toolkit uses DISM to integrate updates into the ISO, so they should be recognised. As boco already said, just check using Windows Update, then wsusou should detect the updates too.
WARNING for ISO modding: Be sure not to remove components (e.g. Windows Script Host (WSH)), they are required for wsusou to work.

No worries. All I ever do to my images is integrate all the relevant patches. No other mods are made

Thanks for the tips. I guess I will see what WU has to say after I install the OS and check it out.

Cheers!

FYI:

There's a difference between WSUSOU and Windows Update. WSOSOU does only have the true updates, and, if WUA doesn't recognize the integrated KBs, will attempt to install them again. Windows Update, on the other hand, will not install the updates itself in that case, but something called "Express CABs". Usually Express CABs do only have the Manifest files in them to correctly register the (already installed) packages in the OS Update Catalog and the SxS Store. Updates integrated by DISM should already be registered correctly, but, as I pointed out earlier, the update system is a mess.

I looked into using DISM to slipstream updates into source files. however not all updates can be slipstreamed. for I while I also used vLite for this.

now I use the reverse integration method. which involves installing the OS, applying updates, using WOU and them syspreping it. from there I can capture a wim file to reintegrate into the OS DVD.
this is the simplistic version.


since windows would have installed these updates, WOU would not install them. this is the long way of doing it but you ensure that all the updates are installed correctly.
