how to integrate/slipstream new updates

Thanks. Take kb3177467 for example. Using wget/curl and the 3 URLs below, one can download these three files:

windows6.1-kb3177467-x64_7203ed8c6247dc914f8a3c95f64d754fe651f998.cab
windows6.1-kb3177467-x64_42467e48b4cfeb44112d819f50b0557d4f9bbb2f.msu
Windows6.1-KB3177467-x64.msu

Code:

http://download.windowsupdate.com/d/msdownload/update/software/crup/2016/08/windows6.1-kb3177467-x64_7203ed8c6247dc914f8a3c95f64d754fe651f998.cab

That first URL (for the cab) is from your export example.

The two msu files are identical in size (9319), the cab is a bit smaller (9146). The filenames contain the sha1 hashes.

Jackpot!

The log itself is in plain text c:\windows\WindowsUpdate.log.

The file is verbose but buried inside are all the direct download links.

last step is to script:
1) parse the log for URLs of the installed msu's
2) curl/wget the all the msu URLs into a directory
3) sort the msu's based on the timestamps of the cab files in \Windows\SoftwareDistribution\Download\*
4) dism the directory into the image

another way to get listing of installed updates:

TechNet Wiki

Code:

wmic qfe list full /format:htable > hotfixes.htm

Also, the update history is available through the link in WIndows Update, I

it also available in a different format through ControlPanel> Programs >Programs and Features > Installed Updates

Still, the amazing thing is that the plain-text log file reports all the complete URLs for msu's of the installed updates.

there is no need to download/install/learn/maintain/deal-with-its-bugs any program, the msu URLs are already available in plain text in the windowsupdate log file, free for the greping.
