hi...recently i forgot all my password in my comp...and its left onli wif the guest account on...how an i get back my password without formating my comp????

try log into safe mode... then choose administrator account... then deleted ur current password... try la maybe this will help....

how to choose safe mode? and how to delete?? at control panel??

Use ERD commander

press f8 when start up the com.delete from administrator a/c lo in control panel under user account

this only works if they did not change/set the default administrator account during setup.


there are several ways to reset the admin password and several tools like Knoppix-STD, EBCD, etc

This method is using Knoppix-STD and i've often use it to reset my laptop passwords on machines that have been disjoined from a domain in which case the local admin password is unknown.

1. download Knoppix-STDKnoppix-STD
2. boot with the Knoppix-STD CD and at the desktop right-click | XShells | Root Aterm
3. at the root Aterm shell console type cat /etc/fstab. This will list all the drive in your system.
4. mount the drive in which your system partition resides mount -o rw /dev/hdax /mnt/hdax where x is the partition.
5. browse to your newly mounted config directory in system32 within the windows directory cd /mnt/hda2/WINDOWS/system32/config which is where your SAM db are kept.
6. Run the chntpw program bundled with knoppix-STD by typing chntpw and run chntpw -l sam system security to list all users on the sytem.
7. to change the password issue the command chntpw -u administrator sam system security. when prompted with Do you really wish to disable SYSKEY? (y/n) [n] answer no. when prompted with Please enter new password: * enter the new password or leave it blank. When prompted with Do you really wish to change it? (y/n) [n] select yes. when prompted with Write hive files? (y/n) [n] select yes.
8. reboot the machine by right clicking on the desktop and selecting reboot. done.


NOTE: do not give links to hacking softwares or those that use brute-force attacks. meaning i will only allow techniques that resets the password but NOT reveal it.

cool
