I will usually run a history for a couple of days, just in case I have to go back and find something. I've had to use the history only a few times, but when it's needed, I can go back.
By the way, I don't know if everyone knows this, but every email and instant message can stay on your hard drive, even though you think they are gone. You really have to dig deep down in your ISP's files to find them.
It's quite amazing how much junk is accumulated on the hard drive, that we would never have known. I've even found some pretty large music files that attached themselves from a site that had theme music. Picture files also, that I didn't have a clue how they got there. And this is in spite of me thinking I had deleted all extraneous files.
When I'm bored, I like to muck around in the files.
That's why it's a good thing to do regular full maintenance every once in a while, say at least once a week. Windows has a wonderful system tools program for that.
