How to Add Devices to Windows Operating System


The device installation process should automatically detect and install any devices present on the system at the time of installation, what if it does not? And what if you need to add devices to the system later? You know how to accomplish the physical installation of most devices, but the other half of the equation is to make sure that Windows properly detects the device and adds the correct drivers. The information ensure that you can add devices to Windows regardless of the device type or the source of the device drivers.

Add Devices to Windows

Procedure : Install a Device

To install a device:

1. Check with your device vendor’s documentation to see if the vendor recommends installing the latest device drivers before connecting the device, so that the PnP auto-detect function works with the latest device definitions. If they recommend this, run the manufacturer’s setup program to install the drivers before you connect the device. The specific steps in the program will vary according to the manufacturer’s programming.

2. Attach the device to the computer.

3. If necessary, turn on the computer and log on as a member of the Administrators group. If the device is PnP compatible, the system should detect and install it automatically.

4. If the device is not detected through PnP, and you did not install drivers earlier, run the manufacturer’s setup program.

5.  If you do not have a manufacturer’s setup disk, run the Add Hardware wizard.

6.  In Windows XP:

a.    The wizard will scan for any new hardware that the system has not yet detected.

b.    If the wizard does not locate any new hardware, select Yes, I have already connected the hardware and click Next. (Select Yes even if you are install- ing a driver without a physical device attached. If you select No, the wizard will end so that you can connect the hardware.)

7.  In Windows 7, do one of the following:

  • If the device is physically attached, select Search for and install the hardware automatically and click Next to scan for any new hardware that the system has not yet detected. If the device is not found, click Next to select the device from a list.
  • If the device is not physically attached, select Install the hardware that I manually select from a list, and click Next.

8.  Select the type of hardware and click Next.

9.  Select the device driver to install:

  • For Microsoft-supplied device drivers, select the manufacturer and model to install. Click Next.
  • For manufacturer-supplied drivers, click Have Disk and browse to select the location of the driver (this location should contain the driver’s information (INF) file, the file that contains the information that the system needs to install the device). Click Next.

10. Click Finish.

11. In Device Manager, verify that the device is working properly.

Procedure: Use Device Manager to Verify Hardware Device Status

To use Device Manager to verify that a hardware device is working properly:

1.  Log on as a local administrator.

2.  Open Device Manager.

a. On the Start menu, right-click Computer in Windows 7 and My Computer in Windows XP.

b. Choose Properties.

c. In Windows XP, select the Hardware tab and click Device Manager..

d. In Windows 7, in the left pane, click Device Manager.

3. Expand the category of a hardware device (for example, Network adapters).

4. Right-click the hardware device and choose Properties.

5. Review the Device status portion of the Properties dialog box. You use this information to determine if the device is working properly.

Procedure : Use Device Manager to Update a Device Driver

To use Device Manager to install an updated device driver:

1. Log on as a local administrator.

2. Open Device Manager.

3. Right-click a device and choose Update Driver Software.

4. Choose Browse my computer for driver software. Click Next.

5. Specify a location to search. Click Next.

6. If the wizard finds another driver, you will be prompted to use that driver or keep the current driver. Make your selection and click Next and complete the wizard to install the driver.

7. If the wizard cannot find a driver, the wizard will end. Click Close.

Procedure : Uninstall Devices

To uninstall a device:

1. Right-click the device in Device Manager and choose Uninstall to remove the driver.

2. Turn off the computer and physically remove the device.

Procedure: Identify Unsigned Drivers

You can use File Signature Verification (sigverif.exe) to identify unsigned drivers on a system. To identify unsigned drivers:

1.To run File Signature Verification, from the Start menu, in the Start Search text box, enter Sigverif.exe, or run Sigverif.exe at a command prompt.

2. Click Advanced if you want to set logging options. Otherwise, skip to step 5.

3. On the Logging page, specify the name of the log file, and whether to append data to the log or overwrite the log each time you scan.

4. Click OK to close the Advanced File Signature Verification Settings dialog box.

5. Choose Start to start the scan. When the scan is complete, any unsigned drivers will be listed in the SigVerif message box.

6. Click OK to close the SigVerif message box.

7. Click Close to close File Signature Verification dialog box.
