Where did you get the Windows 7 driver for your scanner?

Try
http://www.canon.co.uk/support/consu...ducts/scanners
I won't give the rest of the url as, rather alarmingly/depressingly, the
site told me which scanner I have.

I wouldn't be too alarmed/depressed, _if_ you had it connected at the
time; it's not that they have records of you having purchased the
scanner, only that they had some clever script which interrogated the
scanner. (Unless it's that script possibility that's alarming/depressing
you.) Many USB devices self-identify (in fact I think it's in theory a
requirement of the USB spec., though a few cheaper devices implement it
rather flakily).

If you don't clear Cookies on the browser, they will remember.

It's like when I search for "socks" on Amazon, then when I visit CNN
I keep seeing adverts for socks on the screen. That kind of remembering.
Cookies at work.

I regularly clear cookies, just not between web sites :-)
Cookies are cleared at least once a day.

I also clear out any stuff stored by Adobe Flash (on the
browser that has Flash).
