As far as I understand, you mean I have to install Office 2007 SP3 and then the patches KB3191894 and KB3203441 before checking for updates again. Should I install the older speed up patches as well or these latest two only?
However I still don't understand, why Office 2007+SP2 doesn't have problems -without any speed up patches installed- when checking for updates (although it's an older SP).
Please install any applicable of the speed up patches, i.e. all four of them. The Update Search issues in Windows Vista (and even Windows XP) are about applicability of issue-triggering updates. Windows Update would be working fine if it wasn't for a small set of Updates that include the Update for Kernel-Mode Drivers, the Cumulative Security Update for IE and the Word and Excel related Security Updates for Compatibility Pack SP3, MS Office 2007 SP3 and MS Office 2010 SP2.
The Update issue arises if at least one of these Updates becomes applicable and is not already installed. By installation of MS Office 2007 SP3 word2007, excel2007, wordconv2007 and xlconv2007 become applicable at the same time. With Office 2007 SP3, you automatically have Compatibility Pack SP3 installed, too.
MS Office 2007 SP2 is not affected for KB3191894, KB3191897, KB3203438 and KB3203441 not being applicable.
I'm considering the term "speed-up patch" as somewhat euphemistic, because actually these Updates pose a problem to the Windows Update Client. Their being installed manually is what solves the issue, not the updates themselves. Manual installation creates inapplicability until their next incarnation is being released.
An Update for MS Office does not get listed in Update HIstory when installed manually.
