Senseless waste of time

So I get asked why one of the guys can't view a flash demonstration he wants to look at on the web and please sort it out now.
Now, I don't by default grant administrative rights to users. They don't really need them and it stops them from installing all kinds of dangerous rubbish on their machines. This guy was set as a power user and for some reason MS Server & XP Pro doesn't want Flash Player installed without admin rights. After 15 minutes of sodding about I give up and grant the user admin rights, and Flash is his to behold.
I tell him he should be good to go now, and out of interest what exactly was it (ie the URL of the page) that he was so interested in looking at...
Can you guess what happens next?
He doesn't remember. He knows the keyphrase he gave Google to find it, but there are 74.6 trillion results and which one he was looking at is (after 15 mins) a distant memory. Now I could at that point showed him how to use his browser history (ie a fairly basic operation with any web browser I would have thought) but he seemed to have lost interest in the whole idea at that point. I certainly had.
Anyhows, now he has admin priviledges, so the scope for cocking things up on the network multiplies about 20 fold. Looking forward to tomorrow! With a bit of luck someone will ask me how to find file>print. I'm not joking.
