Hello all,
I'm ran the unattended installation for Windows Framework 4.0, aka Update for Windows (KB2819745).

I used "WUSA.exe /quiet /norestart /log
I need to have a way to verify that the update installed.  I know I can look at the "Review your update history", but I need to know where Windows is pulling that history from.I looked in the registry, there is no GUID's to find associated with this update.  I looked in the HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall keys and did not find anything there.
I'm creating package and I need to write a script or action with our packaging software to verify success.  I'm not asking for help with packaging, I"m asking where the heck does the Update History pull it's info from?  If I knew where, I could write a script to verify it.
