What Is Syskey?

About 24 years ago, Microsoft wanted to make its operating system more secure and added an extra layer of protection that is Syskey. So, Syskey was an encryption program. This encryption program used a 128-bit RC4 encryption key to encrypt SAM (Security Account Manager) database that stores user passwords in a hashed format.

Further reading:

In a hashed format, passwords are unreadable by an unauthorized program. Hashed passwords are encrypted so that hackers and cybercriminals cannot gain access to a Windows computer by simply looking up the SAM.

With Syskey, you had an option to specify a password that would protect the authentication credentials of Windows accounts stored in the SAM database. When the password was set, you would need to input the password during the startup before displaying and password prompt.

Syskey Can’t Be Found on Windows 10

Syskey can be found on versions of Windows before Windows 10. It was replaced by BitLocker disk encryption on Windows 10. Why did Microsoft abandon this encryption program?

The first reason is that the Syskey process is quite outdated in modern times. The second reason is that “tech support” scammers would take advantage of Syskey to make money.

Scammers usually call you claiming to be from Microsoft technical support. They say you’re your computer is infected with viruses to convince you to let them remotely connect your computer and fix the issues. Once you believe them, scammers will use Syskey to lock your computer.
