How to Open .sys Files: A Step-by-Step Guide

If you’ve ever downloaded a driver file, you’ve probably noticed that they come in different formats. While executable files (i.e., .exe files) are simple to install, other file types like .sis and .sys may leave you wondering what to do with them. In this guide, we’ll show you how to install .sys files on your Windows computer.

To illustrate this process, we’ll use a Microsoft Bluetooth driver as an example. Let’s get started!

Step 1: Download the Driver

First, visit the download page for the driver you need and download it to your computer. Once the file has downloaded, open the folder location where you saved it.

Step 2: Extract the Contents

In the folder, you’ll see a handful of files, including .sis files and other types of files like .inf and .cat. The .inf file is particularly important because it contains information about the driver that Windows needs to read in order to install it correctly.

Step 3: Access Device Manager

In Windows 7, go to the Device Manager by clicking on the Start button, right-clicking on Computer, and selecting Manage. In the Computer Management window, you’ll see the Device Manager on the left-hand side.

Step 4: Update the Driver

Locate the device that needs a driver update in the Device Manager. It will have a yellow exclamation point next to it. Right-click on the device and select “Update Driver Software.”

Next, choose “Browse my computer for driver software” and then “Let me pick from a list of device drivers on my computer.”

Click on the “Have Disk” button, then browse to the location where you saved the driver files. Select the .inf file and click “OK.”

Windows will then install the .sys file in the proper location, fixing the driver issue.

In conclusion, installing a .sys file to correct a driver issue on your Windows computer is a straightforward process. By following these steps, you can easily install drivers in various file types and keep your computer running smoothly.
