Howto – Clear Windows password with Rescatux

What problems does it solve?

You forget Windows password

Whatever the reason is you have forgotten your Windows password. When you try to login into Windows with your previous password or trying with a blank password it denies your login.

Your former sysadmin disappears

Your former sysadmin is no longer there. It doesn’t matter if you have fired him and he’s angry at you or if he had a fatal car accident. You need to take in control of your Business Windows server.

When not to use this howto

About encrypted Home directories

If you want to recover data from the account you are clearing its password and this account is encrypted this is not the method for you. Find another way to crack the original password.

Locked or expired account

If the account you are trying to clear its password has been blocked or it’s expired you will need to find a way to un-block or un-expire it. Well, you can always use this method and finally figure out that it was blocked.

Network access only

If you have your computer in a datacenter and you don’t have a direct access to it (Screen, keyboard and mouse directly or via a KVM) then RDP won’t let you login into the system with the cleared password account. You need another method that let’s you define a new password instead of just clearing it.

What do you get after performing these steps?

If everything goes ok the next time you boot your computer when Windows login appears you will either be logged in automatically or you will need to select your cleared password account. Just pressing RETURN (I mean that you don’t need to write any password) will log in into the system.
