How would I hide icons in the system tray?

[Fathom Zero]

I'm looking for a solution because I'm tired of turning on uTorrent, only to find that it's been closed when I get back from work. Even more so, I'll be gone from the computer I'm using for a few days and I'd like to leave it running.

Any help would be very much appreciated, as always.

XP will hide system tray icons after a while if the program isn't being used. If someone is closing the program on you, tell them to fuck off when you leave it downloading stuff.

I just figured it out while fixing my taskbar.

Right-click and go to "Properties".

Scroll down to customize and it'll give ya the list of just about every item that was ever in your system tray and allows for configurations of "Hide when inactive", "Always hide", or "Always show."
