strange but interesting

I've been running Vista Home Premium for over two months or so and today
something interesting happened. The computer was 'asleep' and I awakened
it. I rec'd a handful of run time errors each with a different number. I
had no idea what that was about so I rebooted just for the hell of it.

Now when I place the cursor over the various words/links in the right side
of the Start box (Run, Help and Support, Default Programs, etc.) , I now see
an appropiate icon at the top of that window corresponding to the link in
question. Over the 'Help and Support' link I now see a question mark at the
top of the window. I didn't have that 'feature' for the last two months.
Does Vista, albeit rather slowly, attempt to 'repair' itself?
