So you can then use the following command to reset your forgotten user password: passwd username. Next, open the Linux Bash shell and it will log you as root without asking a password. I personally recommend setting the password to Clear (blank) user password. Open the command prompt, type either ubuntu config -default-user root or lxrun /setdefaultuser root.

So don't do that to bypass the protections that have been set in a corporate domain against such personal use of a PC you don't really own and have no right to adminsiter yourself. Run sudo chntpw SAM to see a list of users and to change the admin password or use sudo chntpw u SAM to change the password of a specific user.

It may also not work if the encryption password comes from the TPE module which won't allow you to boot from the external drive which was not first allowed to run as it was not signed.īut anyway it's good to signal users that their Windwos password is not a real protection for their data, and that it can be easily cleared in most cases: suppose your PC is stolen (or seized by the police/justice.), they know what they can do easily to enter your drive and get access to all the contents.Īlso clearing a password this way may invalidate all access tokens that allow you to use some remote sites or storage that will need a new authorization, because the SAM database will no longer have the necessary access tokens.Your PC will then be 'disconnected' from a secure corporate domain and you'll need to contact the domain admin to reauthorize your PC (and fbefore they accept to reconnect you they'll want to inspect your PC, and may force you to resintall it completely). If you have encrypted it using the storage option of Windows, you won't even be able to mount the volume correctly and edit its content from an external tool to clear the password stored in the SAM registry file, you first need the password.

This only works if your Windows drive is not encrypted. SystemRescueCd doesn’t just reset passwords in your Ubuntu, Red Hat, or Linux Mint system: It can also help you recover access to your Windows computer. In here, use your distribution’s command in this fashion.
