Hello, 

 

My roommate is the only user on her computer and she logs in as administrator.  She recently changed her password and can't seem to get back into her computer.  She has tried all kinds of different passwords.

 

We looked for the windows 7 CD but can't seem to find it anywhere.

 

She isn't very good with computers so I strongly doubt she has a restore point, or recovery disk or anything like that.  We did, however, recently back up all of her stuff.

 

I have been googling this but I am nervous about which approach is the best to use.  I was hoping that someone could advise me on how to unlock her computer for her.

If you want to recover the password then use Ophcrack: How to use Ophcrack

 

If you want to delete a password, use this tool (not for PC beginners): How To use Offline NT Password & Registry Editor

 

Both of these tools are live cds, that means they are burned to a disk and booted from the disk, not from windows. Change Boot order from BIOS

I am going to have to use my computer to help her.  I have a MacBook Air, and she has a Dell Inspiron.  My computer does not have a CD/DVD drive.  Will I be able to download those programs onto a USB to use on her computer?

I don't have an apple but hopefully this will work for you.

Now, I can't log into any account on her computer.  No guest account or anything.  How can I tell the computer to run the program on the disk or usb?

Maybe Kal Drogo changed the password!

The link I posted was to create a bootable USB. You will have to set USB as the first device in the BIOS of your roommate's computer. Save the settings and with the USB flash drive attached reboot the computer.

How do I set the USB as the first device in the BIOS?  

Remember, I can't log in at all.  The only thing that I can access is her log in screen.

You have to tap a certain key at boot before you log into Windows. What is the make and model of the computer?

Power down the computer. Attach the USB key. Press the power button and then tap the F12 key. This should bring up a boot menu letting you pick a device.

 

If that does not work, tapping the F2 key at power up should let you access BIOS. There should be a boot section showing boot device order.

Thanks.  

 

Sooo, I am in the middle of downloading ophcrack and I am looking at how to transfer the program to a USB.  However, I am stuck on this sentence...

 

"Now that our USB key is ready, we need to get our .iso image into a format that we can copy to it. Open up a Terminal (it too is in /Application/Utilities, and I’ll assume you know how to use the terminal)."

 

Yeah..I don't know how to use the terminal.  Can you talk me through that part?

You have to open terminal and type the following as shown in the screenshot of the link I posted.

/Users/<yourname>/Downloads/ is where the file you downloaded is located
So  whatever the filename you downloaded would look like this
hdiutil convert -format UDRW -o yourfilename.img yourfilename.iso

Then you have to copy it to the USB drive using the dd command but first you have to identify the USB device name using the diskutil list command

 

I have never done this so i cannot confirm if it will work Try the above and see if you get the img file.

 

This would be much easier if you had access to another windows computer.

 

Edit: In terminal you can type the command  pwd   ( present working directory) to see if you are in 

Users/<yourname>/Downloads/

Edit Edit: If you are not in

Users/<yourname>/Downloads/  when you typed pwd

Then type:

cd Users/<yourname>/Downloads

I am copying and pasting the text from terminal.

 

Loralees-MacBook-Air:~ lolerary$ hdiutil convert -format UDRW-o ophcrack-vista-livecd-3.6.0.iso
hdiutil: convert: no output file specified
Usage: hdiutil convert -format <format> -o <outfile> [options] <image>
hdiutil convert -help
Loralees-MacBook-Air:~ lolerary$ 
 
What I typed is in bold.  So perhaps the problem is that I am not specifying the downloads folder or something like that?

I thought I figured it out but it still didn't work:

 

Loralees-MacBook-Air:~ lolerary$ hdiutil convert -format UDRW -o ophcrack-vista-livecd-3.6.0.img ophcrack-vista-livecd-3.6.0.iso
hdiutil: convert failed - No such file or directory
Loralees-MacBook-Air:~ lolerary$
