This article reviews Trinity Rescue Kit (TRK) a free tool set that allows you to remove a forgotten administrator password and has many other recovery features for Windows.

Update: TRK 3.4 doesn't allow you to change the password on Windows 8 and Windows Server 2012. Follow this guide, to reset a password on Windows 8 or Windows 8.1.

Last year, I wrote a short article that explains what you can do if you forgot your password. Some of those who commented on the article recommended the Trinity Rescue Kit (TRK), a free Linux-based recovery solution. However, TRK can do much more than just reset passwords. Like MSDaRT, which I reviewed some days ago, it can be helpful to recover a Windows installation in offline mode.

trinity-boot TRK comes as an ISO file which you have to burn to a CD. It is also possible to boot from a USB stick. After booting, you have several options for how to start TRK. Most of them are related to possible driver problems you might experience once you start TRK. You can also test the system memory here before TRK starts.

In most cases, the default settings are the best choice. I tried TRK under VMware Workstation 6, and encountered only one minor driver issue. TRK didn’t support my German keyboard. This is not a big deal if you are familiar with the English keyboard mapping. However, I think, this indicates that driver problems might be one of TRK’s weaknesses.

Once TRK has been loaded, you will find yourself on a Linux prompt. Hence, you have no other choice than to consult the documentation. You can do that by entering “trkhelp”. Most of the commands are quite easy to handle; you don’t have to be a Linux expert. However, basic Linux knowledge is sometimes required.

These are the main tools of TRK:


trinity-mountallfs This tool scans all local storage devices and mounts their filesystems. Once you have access to your Windows installation’s filesystem, you can work with Linux commands like cp or rm to make changes. You can also use the text editor vi, but Windows users will probably prefer pico.


The tool behind Fileserver is Samba, the famous Linux implementation of Microsoft’s SMB/CIFS networking protocol. Fileserver allows you to access the filesystem remotely from a Windows box. This way you can change the files of your patient remotely with your familiar Windows tools.


Some viruses can only be removed when the operating system isn’t running, because they replicate faster than the antivirus software can kill them. TRK comes with four different scan engines: Clamav, F-prot, Grisoft AVG, and BitDefender Scanner. This is certainly a nice feature because it increases your chances of coping with new malware. All scanners can be updated online, directly from the TRK command prompt.


This tool allows you to reset any user’s password without knowing the administrator password. Note that if you didn’t export private keys, you won’t be able to access EFS encrypted files anymore. This is always the case with tools that reset the password while Windows is offline. You should also be careful when you disable syskey, because all local passwords will become invalid. Read the manual carefully!


trinity-registry-editor TRK comes with a command-line based registry editor. For example, the ls command lists all keys, and with the cd command, you can navigate to a subkey. This is certainly a very inconvenient way to edit the registry.


Clonexp can create an image of an NTFS partition and copy it to another computer. This can be useful if you want to create a backup of your disk before you start messing with it.


The name of this tool speaks for itself. Undelete only works if the files haven’t been overwritten yet by Windows. If you have ever accidentally deleted important files which you can’t recover via the Windows Recycle Bin, I recommend pulling the power plug of your computer immediately, and then trying to undelete them with a tool like TRK while Windows is offline.

TRK is certainly a useful tool if you are not afraid of Linux. However, it is not really a match for MSDaRT. Microsoft’s solution is not only easier to use, it also offers more tools to recover a Windows installation. But the Trinity Rescue Kit has one essential feature that MSDaRT lacks. It is free!

    all you have to do is read the site’s tutorial and you can reset the vista passwords, instead of begging for help why not actually do some reading about the Topic here…

    Download TRK burn it to a disk, boot from the disk, and at the prompt type winpass -h winusername

    A friend of mine gave me a computer that belonged to a friend of his, which has a password which has been long lost. As soon as I am able to get my hands on a blank disc and put TRK on it, I’m excited to give it a try.

    I’ve been on the forums quite a bit on the trinity rescue kit website and have seen a lot of positive feedback on the program. If it does work as easily as everyone says it does, it’s going to be a huge relief to be able to finally have a sure-fire way to get around the infamous “Vista Password”.

    Wish me luck, and good luck to anyone else using this program.
