They are the same, but I don't want to be bothered to install the Intellipoint first then look for the HID Non-User Input Data Filter. I know what that optional update is for. It's for wireless mouse, wireless keyboard etc. Had it when I had my Vista computer.
It's an optional anyway. I am using a wireless mouse and I had no problem on computer not going to " sleep ".
So, I'll just wait and see if it shows up again in WU.
