Previously, I would check the following registry location for Office updates: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
There are entries something like:
{90140000-0011-0000-0000-0000000FF1CE}
I would then use a reporting tool to look for this to identify where office updates are installed. (LANSWEEPER is a great tool for this kind of reporting)
Recently I needed to do this for an Office Update that was causing issues with opening attachments in outlook.
Something must have changes since i had to do this, so if you have this issue, adjust your registry path:
The proper location to scan is:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\Packages
And search for the actual KB #
you are welcome
and sometimes you can use this path as well: (if the computer is a 64 bit windows 7)
SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\
