How to set additional security for windows by Syskey password


Syskey is the utility that encrypts the hashed password information in SAM database in a windows system using a 128-bit RC4 encryption key that, by default, is stored in the windows registry. Syskey can optionally be configured to require the user to enter the key at boot time as a startup password or load it on removable storage media (e.g., USB flash drive). Generally, windows have a feature of security by adding user password. But if you are not satisfied with a single password on startup you can set an additional password by the Syskey utility.

Syskey utility is an inbuilt feature of windows for securing data by using 128-bit encryption. Syskey was introduced with Windows NT 4.0 SP3. You can add Syskey password on the system which is asked on windows startup. After setting up this password on your windows you can not boot windows without this password and no one can reach your user’s password without knowing Syskey password. By using Syskey password your system will have two layers of security.
