Phantom User on Win7

I have a windows 7 small PC with two user accounts "Guest" and the one I use. I rarely if ever log in on the guest account. However sometimes I would come back to this PC and notice it is logged in as guest. This usually happens in the morning. This is a PC only I ever use yet I often see it signed in as guest without my doing. I've also noticed that after this happens my bluetooth headset acts odd. I can hear feedback from the microphone. As in instead of playing just the sound from the PC on the earphones I can barely hear them and instead I hear the sounds from the microphone. What could be causing this?

Think you might have a ghost there em could you not just disable the guest account and see if that makes a difference. But I never seen this problem but i would just disable the account if not in use

someone is whispering you something . *Use only your admin account*

I didn't think of ghosts!

Thanks layback bear, that might be it. Though if I remember correctly auto-login is disabled.

Any way to fix the BT microphone problem? That irritates me more. It seems when the guest account logs in the bluetooth headset microphone turns on with the headset until I restart the computer. I do realise that there is little information to diagnose the problem but I don't know what's causing it. I am hoping somebody has experienced something similar and found a possible solution.

I don't want to disable the account completely because occasionally I actually do have a guest and I'd rather they use the guest account rather than mine.

Would you just not put a password on the guest account so and see if this help's. As for the Mic, I can't answeo this but maybe someone else could post and help. But if it is only happening when it logs in by itself then try the password and see what happen's.
