How Do I Reinstall A Devicewindows 7 From Command Prompt

Windows

Installing or reinstalling a device driver on Windows 7 can sometimes be a daunting task, especially if your device is not functioning properly. However, with the help of the Command Prompt, you can easily reinstall a device driver and get your hardware back up and running smoothly. In this article, I will guide you through the step-by-step process of reinstalling a device driver on Windows 7 using the Command Prompt.

Step 1: Open Command Prompt as Administrator

First, we need to open the Command Prompt as an administrator. To do this, click on the Start button, type “cmd” in the search box, and right-click on “Command Prompt” from the search results. Then, select “Run as administrator” from the context menu. This will open the Command Prompt with administrative privileges.

Step 2: Identify the Device

Before reinstalling the device driver, we need to identify the device for which we want to reinstall the driver. To do this, we will use the “Device Manager” utility. In the Command Prompt window, type “devmgmt.msc” and press Enter. This will open the Device Manager.

Once the Device Manager is open, look for the device that you want to reinstall the driver for. It will be listed under the appropriate category. For example, if you want to reinstall the driver for your graphics card, look for “Display adapters” and expand the category to see the listed device.

Step 3: Uninstall the Device

Now that we have identified the device, we need to uninstall its current driver. To do this, right-click on the device and select “Uninstall” from the context menu. You may see a confirmation dialog asking you to confirm the uninstallation. Click “OK” to proceed.

Note: Before uninstalling the device driver, make sure you have a backup of the driver in case you need to revert the changes.

Step 4: Reinstall the Device Driver

With the device uninstalled, we can now reinstall the driver. In the Command Prompt window, type the following command:

pnputil /add-driver <path_to_inf_file> /install

Replace “<path_to_inf_file>” with the path to the .inf file of the device driver you want to reinstall. The .inf file is usually included in the driver package downloaded from the manufacturer’s website or the installation disc.

After executing the command, Windows will search for the specified .inf file and install the device driver accordingly. You may need to restart your computer to complete the installation process.

Conclusion

Reinstalling a device driver on Windows 7 using the Command Prompt can be a useful technique when your hardware is not functioning properly. By following the steps outlined in this article, you can easily reinstall a device driver and get your device back to its optimal state of operation. However, keep in mind that it is important to always backup your drivers before making any changes to your system.
