Dell Update reports there's an update for "SupportAssist OS Recovery Tools". When I click Install Now, it looks like it installed, but it reports the same update again an hour later (or immediately if I force update check).
I have this problem on two XPS 13 9550's, and this thread shows five other users (and counting) having the problem on machines including XPS 15, Inspiron 15-7569.
Is Dell aware of this installer bug, and will there be a fix? That notification balloon is really irritating.
