Windows password lost what to do??????
It may be the questions when you lost one. Today I am going to talk about cracking or recovering the windows password using OPHCRACK.
According to windows, there are no way of recovering a password and you must format your system.
But you can try by booting your system in safe mode. If there's a administrator password set then this cant be a option. So let's try Ophcrack .
Ophcrack is a Rainbow Table based freeware which uses LM hases invented to crack passwords.
But if you are willing to reset your password rather than recovering than you can go through
Reset password of windows xp/ vista/ 7
Thus to use the Ophcrack just follow the following steps:
Step 1:
Download Ophcrack from the following links below:
For Xp (415.65 MB): http://space.dl.sourceforge.net/project/ophcrack/ophcrack-livecd/2.3.1/ophcrack-xp-livecd-2.3.1.iso
For Vista (496.24 MB): http://space.dl.sourceforge.net/project/ophcrack/ophcrack-livecd/2.3.1/ophcrack-vista-livecd-2.3.1.iso
Then just burn the iso file into CD by any iso burner. But make it bootable.
In case of USB installation just refer to my article on Making a USB drive bootable.
Step 2.
Now just insert the CD or USB in your computer. Then you must put the boot priority of CD to 1st if you are booting from CD and if you are booting from USB then you must put the boot priority of USB to 1st.
To do this you need to go to bios setup and change the order. For most of the systems the keys like DELETE, F10, F2, F12 etc are used for going to the Bios setup.
Step 3.
After booting from the Live CD, wait for it to load and select Ophcrack VESA mode(Recommended). If you have a graphics card you can try Graphics Mode.
If you have more than one partition containing the password hashes in-case if you have more than one OS installed it will ask you to select one. But most of the computers will have only one hash partition, so you may not see this step. Select any partition if it gives a multiple options and press enter.
Step 5.
Wait for Ophcrack to run find your password. After getting the password you need,you can simply click exit even if the progress is not 100%. No need to wait till end.
Step 6.
After the process it will ask you to press any key to exit Ophcrack. Then Type ‘y’ to shutdown the System.
Thus it is a simple tool and easy to use. It can recover upto 14 alphanumeric passwords.
To crack a strong password the vista and xp special tables can also be found.
