Ok, so my IRL brother is trying to hack my computer, so he burned this program called Login Recovery, and all he has to do is put this into my computer, and it shows the encrypted password. Once he has that, he uses some program that decrypts it, and there he has it.

I'm looking for a program that won't let you put a disk into your computer when you're not logged on, or something along those lines.

I know that you can just take out your hard drive, disk drive, or whatever... but that's too much of a hassle.

I go one better and reset the administrator account passwords directly. Very Happy

Anyway, your best bet in this case is to put a bootup password into the BIOS to prevent the machine from even booting without it. This is risky, however - forgetting the pass is NOT a good idea.

ONLY way to do what you want to do is to encrypt entire hdd. From the start to the end (and with pre-boot authentication). That way he cannot get into system files or anywhere else, since EVERYTHING is encrypted. All you need to do is to choose a good, complicated and long passphrase and make sure you dont let him know it...and when you are away from the computer, lock it (screensaver with good Windows passphrase, press Windowskey+L) or turn it off. He cannot even install keylogger on the system since there is no system where to install it (since system is encrypted). All he can do is sneak your passphrase when you type it in or install hardware keylogger. Otherwise he is 100% out of your computer forever.

Luckily, there is one free program for that purpose, Free Compusec. Smile

When I was away in Hawaii, him and his friend took out the battery from my motherboard which took off the BIOS password. I havn't tried that whole encryption thing yet, just the BIOS PW seemed to be working.

Is there anything that I can do so he can't get my password even if he takes out the Motherboard's battery?

No, it does not work as you already pointed out. Simply taking off the battery resets the password.

Encrypt entire hdd with pre-boot-authentication supported program (like Compusec Free). Everything else will fail, as pointed out already.

You could get a case which you are able to lock. This would prevent removal of the CMOS battery in order to reset the BIOS.
