Physical Presence Check

To prevent malicious software attacks, a Physical Presence Check must be performed to inject a “new” key or “clear” a key. During the next reboot after a new key is written to Public WMI, the following message will be displayed to the user:

Microsoft Windows Product Activation Key Change

A change to the Microsoft Windows Product Activation Key is pending. Please contact Hewlett-Packard support

(www.hp.com/support) for instructions on how to complete the request. Otherwise press the “ESC” key to continue without any changes.

Windows Product Activation Key (020)

ESC – continue without changing

For more information, please visit: www.hp.com/go/techcenter/startup

A Physical Presence Check is not required if the system is in Manufacturing Mode or if the key has not been set since it was last cleared by a complete BIOS re-flash.

Computrace

The Absolute Computrace Pre-boot module writes to the hard disk if it detects the needed hard drive components are no longer present. This provides persistent support and prevents the malicious deletion of files from the system. However, this method can impact OS stability. Pre-boot module support will fail when the OS partition or the hard drive is encrypted.

In Windows 8, a new method has been proposed. The Windows Platform Binary Table (WPBT) is a fixed Advanced Configuration and Power Interface (ACPI) table that enables boot firmware to provide Windows with a platform binary that the operating system can execute. The binary handoff medium is physical memory, allowing the boot firmware to provide the platform binary without modifying the Windows image on disk. In the initial version, the WPBT simply contains a physical address pointer to a flat, Portable Executable (PE) image that has been copied to physical memory.

If you are running Windows 7 or an older OS and the HDD is not encrypted, use the older method (changing the OS file).

If you are running Windows 8 and the HDD is encrypted, publish WPBT. For older OSs, the WPBT will be ignored.

For more details, refer to the WPBT published by Microsoft.
