Device Manager displays all devices installed in the system The devices shown in Device Manager represent the computer’s hardware configuration information. The Device Manager display is recreated each time the computer is started, or whenever a dynamic change to the computer configuration occurs, such as addition of a new device while the system is running. You can use Device Manager to enable or disable devices, troubleshoot devices, update drivers, use driver rollback, and change resources such as interrupt requests (IRQs) assigned to devices.
Two types of devices are hidden by default in Device Manager. Non–Plug and Play drivers, printers, and other classes of devices that are not typically useful in configuring or troubleshooting hardware issues are hidden. Also hidden are devices that were previously attached but are not connected to the computer at the present time, also known as non-present devices. Typically you will not need to view hidden devices unless you need to configure or troubleshoot hardware. Each category of hidden device requires a different procedure for Device Manager to display the devices in that category
To view currently attached non–Plug and Play drivers, printers, and other devices
In Device Manager, on the View menu, select Show hidden devices.
The following procedure shows non-present devices for this instance of Device Manager only.

According to a posting by a Microsoft representative in one of the company’s support newsgroups, a “Windows XP SP3 Hotfix Preview Pack (unofficial)” is a fake, not made by Microsoft, and worth avoiding.
In a LAN with both DHCP and statically assigned IP addresses, to determine, using Ping, what IP Addresses are in use, ping xxx.xxx.xxx.255 where xxx represents the network id e.g. 192.168.0.255. Then arp -a to list live ip addresses on your subnet. Compare to dhcp scope and you have your list of static ip addresses in use.
