Help Please! Running Miner in the background (Windows)

[Punktonic]

Hey all.  Was hoping someone could give me some advice on my question, still a bit of a noob.  

I need to know how to setup BFGMiner to run in the background, ideally without any sign it's running, and not stop when I log off and another user logs on.

My laptop can't mine anything, but we have a shared computer in the house and every user has a login and password. I'd like to set it up so that it keeps running when I log off, stays running when nobody is logged on, and continues running when another user logs on.

If anyone could give me step-by-step instructions on how to use BFGMiner to do this, or GUIMiner, it would be greatly appreciated.

Thanks!
