Vista - Wireless mouse and the ole screen saver issue

Okay..I know this has been discussed before...but my question is a bit
extended from earlier discussions.

I bought a Logitech mouse...and now on my Vista operated machine...the
screen saver does not always come on.

Upon reading earlier post..it was said I needed to go into updates to find
the "HID non-user input data filter"..and install. Well, updates never found
it nor is it a part of a previous update that I have done. After much
looking, I found the update on the microsoft webpage. I was able to download
it.

It is an .cab extension file. I had downloaded TurboZip to extract the .cab
file since nothing I had does that.

My question is..where the heck do I extract it to? I dont want to assume
anything so I thought I would ask.

Any thoughts are appreciated.
