HP and Windows Passwords
HP security features and Windows operating system security
features work independently from one another. For example,
a device disabled in Computer Setup cannot be enabled in
Windows.
Some password options are provided by your HP software,
and others are provided by your operating system. HP passwords
and Windows passwords are also independent of one another.
The following table lists the different passwords used by HP and
Windows and describes their functions.
For additional information about Windows passwords, such as
screen-saver passwords, refer to Start > Help and Support.
