First, make sure you are logged in as an administrator. Check out these step-by-step instructions:ġ. So with a system privilege command prompt in your hands, you can actually do a lot of stuff including creating new accounts to resetting administrator password to gain access to the password protected Windows. This backdoor allows you to run command prompt (cmd.exe) with system privilege from the Windows 7 login screen. This method is a bit restrictive because it requires an administrator privilege to the computer in order to make changes to the system but it does not involve installing any third party software or changing any system files like the old DreamPackPL. Here is an interesting method which I recently discovered that allows you to plant a backdoor to your Windows 7 operating system so that you can always reset or even add a new user account without even first logging in to Windows. As long as you can boot up the computer with CD or USB, there are quite a lot of tools that allows you to reset the user account password even if you don’t know the original password. If BIOS is secured with a password to prevent changing of boot order, you can change the jumpers or remove the battery from the motherboard to clear the CMOS settings. For example, you can use Kon-Boot to login to any user account in Windows with any password by booting up the computer with the CD or USB.

As long as there is physical access to a computer, it is always possible to gain access to the operating system even if it is password protected.
