How to Recover Windows Password with USB Flash Drive if you don’t Have CD Drive

:( The bad thing is you forgot your windows password. And the worse thing is you didn’t have a CD drive for some reason. But the good news is that there are still some programs that can help you!

Before using windows password recovery softwares, you should know the following basic things of windows password recovery:

1. Password Hash:

When you type in password in Windows XP, NT, 2000 login windows, windows operating system converts (encrypts) these passwords in something like this: 7524248b4d2c9a9eadd3b435c51404ee

This is called password hash and this encryption is done using high level encryption schemes.

2. SAM Files:

In windows Operating system, these password hashes of every user account are stored in SAM Files. When user types in password on login screen, windows compares this SAM file contents with typed password and allows access (if matched). So, it is necessary to get these SAM files, if you want to recover your password.

3. Problems with SAM Files:

There are two problems with recovering passwords from SAM files:

This SAM File is locked during active windows session and hence cannot be accessed without booting. Thus, you have to boot system from another Operating System (NTFSDOS or Linux usually) and then copy SAM File to floppy drive or convenient external device like USB flash drive. Even if you copy this SAM file, since the SAM File is in encrypted format, you can’t see passwords in plain text form and so you have to recover (actually crack) passwords. For this purpose, either Dictionary or Brute force attack is implemented. But it still take a very long time if you password have many characters. The most convenient windows password recovery way is to use some programs to change the corresponding position in SAM file. Then you can log in again with no password.

Nowadays, most of windows password recovery tool is to boot up with CD. Fortunately, there are still a few windows password recovery tool support USB flash drive recovery. But you have to pay for some.

Enjoy these windows password recovery tool!

    Windows password reset you can try to use the last method. Not only it is free one but also you can create a new reset disk. For this if you also lost your password you can use it directly.

    I have also used USB driver to reset lost Windows password. It is pretty easy! But when we have no password reset disk, to use some password reset tools such as Windows Password Killer can be a nice choice.

    I had hard times resetting my win7 password... I googled dozens of methods but nothing seemed to work. I dunno why, maybe they were outdated.
    Then I followed this video:

    and it worked perfectly! Probably because it is quite new.

    I ended up doing a fresh install on my windows 8 laptop. It took a little longer but the headaches weren't there if I were to try to recover it.

    I also didn't have anything important so I was willing to delete everything on the laptop.

    Through creating a disk to reset Windows password is indeed helpful method. Thanks for your share of how to create the disk. I think the most important when you create a disk can be the software is safe or not. Normally, when you choose software to create the disk, most software you can see in Google may be all effective but cannot guarantee safe. According to my own experience I recommend Windows Password Killer, which is safe, quick and effective and you can learn from:
