The first thing I'd do is get my head straight and realize that :
if I don't trust him
He shouldn't be using my computer at all.
A computer is a very personal thing, and anyone who doesn't respect that shouldn't be near it.
On a technical note:
I would go to Control Panel/ Users and make sure that my account has administratory priveledges, and that his is either deleted, or changed from administrator to something more limited.
I would then change my password, and keep it in a safe place. (Not stored in my computer files!)
Also, you should realize that password protection is about as reliable as your car alarm.
There are many ways to break a password, most of them are simple enough that I feel confident I can get into any Windows Operating System, and I'm not a prodigy or anything.
In other words, my best advice is this:
Don't put anything on your computer you don't want others to see, because, eventually..
someone will. Back up your personal things to CD's, Dvd's, or get yourself an external hard drive to keep personal things on, and when you're not using those items, disconnect it, and lock it up.

you can change your password on firstinmath by hacking into someone's account
Change the password on your account, then they will no longer be able to access your account from the old machine as it will still have the old password recorded.
If someone steals your hotmail account and didnt change your password yet all you have to do is change it but if they did change the password you can only click forgot password and that's what you do when that's happenes.
Change your password
Only if they have your password.
I suggest delete the account, report it, or just change the password. =D
you can change your password i forgot my email nd i cant change my password
Yes, only you can change your status........... if you give someone your password and they get on your account, then they can change it.
An account compromise is the unauthorized use of a computer account by someone other than the account owner. Acquiring or Brute Forcing a password of an account that is not your own. To be sure you do not loose Data or general account integrity: Change your password often ; you might consider use of a password generator to rate the strength of selected passwords. A good password idea : there are none. Use passwords you can remember, do not use anything directly related to personal information. Check your security program status and update your computer often to ensure you are not being victimized by keyloggers or other malicious software that can compromise your computer or internet security.
Not that I know of. If someone gave an account away, someone else would change the password on it. You need to buy it.
