This option is available only if you are logged on as an administrator or as a member of the Administrators group. Warn To display a warning message, allowing you to allow or deny driver installation, whenever an installation program or Windows attempts to install a device driver without a digital signature. This is the default behavior. Block To prevent an installation program or Windows from installing device drivers without a digital signature.

To use Sigverif, complete the following steps: 1. Click Start, click Run, type sigverif, and then click OK. 2. Click Advanced, and then, on the Search tab, select Look For Other Files That Are Not Digitally Signed. 3. Select the Include Subfolders check box, and then click Browse. 4. Locate and then select the %SystemRoot%\System32\Drivers folder, and then click OK. Click OK again, and then click Start. Sigverif might take quite some time to compile the list of unsigned drivers. When Sigverif completes, it displays its results. You can also find the results in the Sigverif.txt log file in the %SystemRoot% folder. You can open the log with any text editor, including Notepad.

Managing Hardware Devices and Drivers
Several categories of devices have Control Panel applications associated with them that allow configuration of those devices. Such applications include: Keyboard Mouse Phone And Modem Options Sounds And Audio Devices
In addition, you can manage network cards using the Network Connections folder and printers using the Printers And Faxes folder. Installation, removal, and configuration of devices using these applications are subject to the same limitations as Device Manager: many tasks require membership in the Administrators group. Enumerating Hardware with System Information
The System Information utility, MSInfo32.exe, lists (or enumerates ) installed devices in its Components node. You can use MSInfo32 to examine and export the devices on the local computer or on a remote computer. System Information also allows you to launch, from the Tools menu, the File Signature Verification Utility, Sigverif.exe. Practice: Installing Device Drivers
In this practice, you will install a network adapter, change the Driver Signing Options, and then return the computer to its default configuration. Exercise 1: Install a Network Adapter
1. Open the System Properties page from Control Panel, and then, on the Hardware tab, click Add Hardware Wizard. 2. Click Next and wait for the Hardware Wizard to scan your computer for new devices. If you have not added any devices, the wizard will ask whether the new device has been connected. 3. Select Yes, I Have Already Connected The Hardware, and then click Next. 4. From the Installed Hardware list, scroll to the bottom, select Add A New Hardware Device, and then click Next. 5. Select the Install The Hardware That I Manually Select From A List (Advanced) option, and then click Next. 6. From the Common Hardware Types list, select Network Adapters, and then click Next. 7. Select Microsoft as the Manufacturer, and Microsoft Loopback Adapter as the Network Adapter, and then click Next.
