I never really suspected Adobe was causing your CPU usage anomoly - with the possible exception of context menu concerns, as it may have pertained to the sustained spike.
You could try using all Vista drivers for chipset and USB devices, but that approaches nonsense.
I wasn't guessing when I posted:
It is not often that I disagree with my esteemed colleagues.
The CPU spike is caused by activity over the USB, which requires CPU time. Yes, your wireless mouse is USB.
You are observing a driver issue, one that may or may not be corrected in the future with a driver update - whether that driver is for your chipset, wi-fi, mouse, or any other USB device. Most historical reports of this anomoly remain unsolved.
For those people experiencing a "normal" spike, you are also affected by this driver issue. Is it a problem? Apparently not.
