Don't know what you read online,but a strong password is not easy to break... you just have to know how to create one. Check this for example.

Password Protection: How to Create Strong Passwords

And you can add a strong password to the BIOS, to Windows login, and to files... and if still not enough, add your files to a zip or rar folder which you can also add a strong password to... and you can even hide and password protect or encript a disk partition where you save your files, with specialized software.

Just one example:

it is very easy to break bios password . if you just remove the battery from the mother board and put it again . the bios password is erased automatically and you can easily login to the system. and i have a tool to break the any kind of windows login password. so both are not secured so give me some ideas dude. i already tried all those things.

1. Computer cases (most I've seen) have the way to use a lock..

2. Any strong password can be hacked but it takes a long time to achieve it with special software (and honestly, who would want to wait for months) so those Windows login passwords you have broken may have not been strong enough...

3. And if your information is on Office files you can add strong file passwords and use other passwords to protect each page after you insert a Word document into a xls Worksheet, hide the text, and another password to protect a xls/xlsx book, store them in ZIP/RAR or other compressed folders under password, in hidden locked and protected partitions or USB hard drive, flash drive, CD, DVD or Blu-Ray disk, etc.

You didn't mention partition locking software... did you break that to?
4. Disk or partition protection software use encryption and as far as I know, encryption can't be broken or at least without expensive software and after a long process.

The disadvantage is you have to make sure you don't loose/forget the password and use a HDD that's in perfect condition because the encryption can make it impossible to recover from another Windows installation, computer or the web.

5. And to make absolutely sure no one will hack your information, why not back it up in removable media that you can keep under lock, carry with you, save in a bank safe deposit box... if it's very important to you or valuable, that would be the best way to protect it and keep from stealing.

one more question guys. actually i encrypted one folder then i asked me to backup the key to decrypt the file in another machine. and i installed the key to the another maching to open the encryped file... so what is my question is. i dont know how to uninstall the key from that machine so that no one can view that file again in that machine.

I don't think that's what the program meant.. backing up the key may have meant to keep the key safe on removable media in case of computer failure, to use it on any other computer you want to access the files from.

1. I'd have to know which encryption program you used to install it and know exactly what it meant.
2. you may have to install the program on the other computer before you can uninstall the key... (if you haven't installed it already).

iam using bit locker encryption which is pre installed in windows 7 ultimate. so i encrypted one folder so it gives me a 200kb file to decrypt it on another machine. so i double clicked that file on that machine and i installed it. so if i encrypt any file in my computer i can able to view that file in both the machine.
