Microsoft update (MSU) does not find updates for other Microsoft products (e.g. Office) after MSU update

This post relates to an earlier thread of mine to fix a problem with Microsoft Update (MSU) during which I had to re-install MSU under Windows 7, 64bit, SP1. I installed this Microsoft update to fix the problem.

However, in the process of fixing the problem I had also unchecked the setting "install updates for other Microsoft products" in the MSU setting, as is shown below in highlighted yellow [unfortunately in German, but the idea should be clear]. This screenshot is from the Office online help where it explains that the checkbox should be checked to find Office updates.

However, I unchecked the box before installing the MSU update as an attempt to solve my original problem. I plaed to check it again later.

To my suprise, the checkbox disappeared after the update and now MSU only searches for Windows updates. See screenshot after the MSU update: the checkbox disappeared.

On the start page of MS update it can be seen that it only searches for Windows updates. See screenshot, first yellow highlight from top. [In German: "You receive updates for: Windows only"]

In the row below [second highlight from top] it says "Receive other updates for Microsoft products" and the link points to this somewhat oldish strange site at Microsoft, relating to Vista (!): http://www.update.microsoft.com/windowsupdate/v6/thanks.aspx?ln=de&&thankspage=5

This all looks very strange to me. Could it be that this is a bug in the MSU update from November 2015?

I would be glad to get your help on this!
