I do confirm too. After having seen for one time this software update tool, I attempted to use it but it did not work (error + infinite refresh). Thereafter I rebooted my system, launches it with a /DEBUG parameter but the tool disappeared from the menu!!! (no more yellow dot).
What makes me questioning how this is possible: the software version remained the same (5.55.7108) and there was no notification of an update...
Or does the tool appears only if some required updates are detected? Ugly.
I upgraded my other PC to version 5.55.7108 version, the update software tool was proposed in the menu on my other PC.
I used it to perform the proposed updates and thereafter the tool disappeared from the menu!!!
