Remove - The Remove button lets you remove a device from the registry and from memory. The Print button lets you generate a report of the devices in the computer. You can print a summary report for your computer, a report for a specific device, or a report for all the devices installed. A report lists the devices in your computer, the properties of these devices, and the resources each device uses. Disabled devices are still present in the system, but they do not use protected-mode drivers.
