Open The Hardisk ,
Bring it to anywhere.

Or open the ram ,
Bring it anywhere.

Because all the password is crackable ...
Just the time it take..

Yeah.. Indeed.
I think better set long2 password+symbols etc.
If i'm not mistaken lopthcrack cannot crack long2 password.
Correct if i'm wrong because i tried it myself on my pc.

windows xp password are useless.. use 3rd party software .. remove the whole password also can

What do you mean and how?

Here But u need to search for the ahem version..

I still have to thank you on guiding me how to use OphCrack that time

where i cn geet tat ahem..hehe..

I'm really learnig alot from this. Thanks to those who contribute. I don't want to share with my brother beczo he everyday play game, and another younger brother PMR coming ....

Use Random Password Generator and change it everyday Link

This way is much secure

Err no need whatever crap software lah.

Just unplug your CDROM / DVDROM power cable from your casing (when you don't use it)

Disable boot via USB in your BIOS.

Change password every 1~2 weeks which consists of 14 alphanumerical + special symbols like !@#$%^&*()_+|"?><

That will make your computer secure from being accessed.

Then, the DVD rom will loose a bit if do that many times.

hmm....the same thing also happen in my family, i used the admin user and change the name, then create a new user with the same name as the previous admin. He was totally shock how i crack his pass, but it was too late. Now he always detach the power supply cable and hid it somewhere (dont have spare and not going into so much trouble just to use my lil bro pc)

yea, cut the power supply is the best
simple and easy.
or add bios password.

wow... extreme measures hah...
gave me an idea oso to keep my lil bro from playing games all the time n not studyin... he got pmr comin...

I used 2 USB

1) 64 MB
2) 256 MB

task is to scan pdfs that are zipped

64 MG USB took abou 1 minute
256 MB USB took about 13 sec
HDD took about 10 secs

Under load
HDD 13 secs
256 USB 19 secs

so in the end... even if the HDD is under heave load
it still beats the USB

my method is crude, but should be sufficient to prove a point
however, I dont have access to more "modern" USB devices
maybe those will yield better results

maybe your brother have a secret linux livecd to hack your account

obviously he used administrator to login to ur comp la... set admin pass, change pass regularly...

what obviously? the only obvious thing I see here is you know nothing. There's tools that can completely remove all Windows passwords, including Administrator password. The solution? Install Universal Shield, the next best thing to sex when protecting your files. It installs as a service so no one can disable it. If anyone try to uninstall, it will ask for password, if wrong password given, it will fake the uninstallation process. You can choose to hide the whole drive (just make sure you didn't hide your drive that have Windows files in it), a folder or just a single file, your wish. Then your brother will be fcuked up and he'll give up someday because he won't be able to crack it unless he can bring teh hard disk to another PC and play the game there...

I did try with XP installed with my VM. It was easy enough to go to safe mode and disable the service so that you can log on as build-in local admin account.

It was a little tricky for those protected files. I could actually see those files once in safe mode so I figured something has to be loaded in normal startup. And then I come across this one:

lol?

So simple solution.

The only protection that cannot be undone or take a seriously long time to undo is probably encryption based protection. I'm pretty sure you cannot encrypt the whole HD itself without affecting the booting of XP. In any case, you can override the local admin password (in fact, any users password, and if you're smart enough, you can even change it back so that they don't know you did it) using a LiveCD. Anyhow, he'll be able to boot into the system. So in other words, the solution you provided is not as godly as you think.

Know nothing huh? zzz

BIOS password protection can be reset easily and those USB holes are everywhere on modern PC nowadays.

ooooo really? if you go here, the 18th feature in the list, developer Everstrike said that:



I've tried it myself and it's true that Safe Mode defeat the protection! I've sent Everstrike an email and let see what they'll respond to this. About encrypting, that's gonna be one hell of a job. Encrypting would take times, especially when the data to encrypt are large in size, and decrypting back... I'm too lazy to do that back and forth everytime I don't want anyone to mess with my game...
