Go to

https://www.microsoft.com/en-us/howtotell/Hardware.aspx for illustrations of the various types of

Genuine Microsoft labels.

• In the People’s Republic of China, the Genuine Microsoft label is required on all computer models preinstalled with any version of Windows 10.

• In other countries and regions, the Genuine Microsoft label is required only on computer models licensed for Windows 10 Pro.

If you have set both the supervisor password and power-on password, you can use the supervisor password to access your computer when you turn it on. The supervisor password overrides the power-on password.

Hard disk passwords

The hard disk password prevents unauthorized access to the data on the storage drive. When a hard disk password is set, you are prompted to type a correct password each time you try to access the storage drive.

To set the hard disk password, select one of the following types:

• User hard disk password only When a user hard disk password is set without a master hard disk password, the user must enter the user

hard disk password to access files and applications on the storage drive.

• Master hard disk password + User hard disk password The master hard disk password is set and used by a system administrator. It enables the administrator to

access any storage drive in a system or any computer connected in the same network. The administrator can also assign a user hard disk password for each computer in the network. The user of the computer can change the user hard disk password as desired, but only the administrator can remove the user hard disk password.

When prompted to enter a hard disk password, press F1 to switch between the master hard disk password
