public WindowsComputerSystem()

Method Details

getWmiQueryExecutor

protected abstract WmiQueryExecutor getWmiQueryExecutor()

Returns the WMI query executor for this platform.

Returns:

a non-null WmiQueryExecutor

getManufacturer

public String getManufacturer()

Description copied from interface: ComputerSystem

Get the computer system manufacturer.

Returns:

The manufacturer.

getModel

public String getModel()

Description copied from interface: ComputerSystem

Get the computer system model.

Returns:

The model.

getSerialNumber

public String getSerialNumber()

Description copied from interface: ComputerSystem

Get the computer system serial number, if available.

Performs a best-effort attempt to retrieve a unique serial number from the computer system. This may originate from the baseboard, BIOS, processor, etc.

This value is provided for information only. Caution should be exercised if using this result to "fingerprint" a system for licensing or other purposes, as the result may change based on program permissions or installation of software packages. Specifically, on Linux and FreeBSD, this requires either root permissions, or installation of the (deprecated) HAL library (lshal command). Linux also attempts to read the dmi/id serial number files in sysfs, which are read-only root by default but may have permissions altered by the user.

Returns:

the System Serial Number, if available, otherwise returns "unknown"

getHardwareUUID

public String getHardwareUUID()

Description copied from interface: ComputerSystem

Get the computer system hardware UUID, if available.

Performs a best-effort attempt to retrieve the hardware UUID.

Returns:

the Hardware UUID, if available, otherwise returns "unknown"
