Windows comes preloaded with an arsenal of drivers — software that lets Windows communicate with the gadgets you plug into your PC. But if you install something that’s either too new for Windows Vista to know about or too old for it to remember, you need to know how to change the driver for a device that isn’t working in Windows Vista.

1. All you need to do is open up a command prompt and type in the following: driverquery. That will give you a list of the drivers and date associated to each. If you want more information, like the actual driver file, you can use the /V command, which you might consider pairing with more so it doesn’t go flying.
2. Device drivers are a big nuisance when it comes to running different devices and software on windows machines. Windows users have complained for years that they find it difficult to search and install drivers as it is hard to find a driver for each device separately.
3. Step 4: Finally, check the box labelled Device driver packages and then click OK button. Click Delete files button when you see the confirmation dialog to begin deleting old drivers from Windows 10. Simple as that! You can also free up space by deleting Windows Update cache in Windows 10.
4. Answer: Files which are given the.DRV extension are known as Device Driver files, however other file types may also use this extension. If you are aware of any additional file formats that use the DRV extension, please let us know.
5. If you are downloading drivers to install on another device, you can copy or extract the driver files to a USB flash drive and connect the USB drive to the other computer. After the drivers have been downloaded, you must determine how the drivers are packaged.

PC users often blame Windows operating system for eating up GBs of disk space over time. This is because, a significant number of Windows users never try to delete temporary files and old files created by Windows operating system.

Other than deleting temporary files and uninstalling unwanted programs, there are tens of ways to free up disk space in Windows operating system. It’s just that most users are not aware of these methods.

Deleting previous version of drivers in Windows 10

We have previously talked about deleting Windows.old folder to free up disk space after upgrading to newer version of Windows 10. In this guide, we will show how you can free up GBs of disk space by deleting old device drivers in Windows 10.

You likely know that Windows 10 automatically installs new device drivers in the background using Windows Update. That is, Windows Update automatically downloads and installs hardware drivers when they are available. When Windows 10 installs a new driver (using Windows Update or other sources), it keeps copies of previously installed device driver packages so that users can restore previous version of a driver if there is any issue with the new driver.

Fortunately, there is a provision in Windows 10 to delete old device drivers without the help of third-party tools. You can delete old Windows 10 hardware drivers in a few mouse clicks to free up disk space.

When you delete old device drivers in Windows 10 using this method, Windows 10 keeps the most current version of driver packages and will delete all previous ones. So we advise you periodically delete old drivers to regain disk space.

Steps to delete old drivers in Windows 10

Here is how to delete old device drivers in Windows 10:

Step 1: Open up This PC, right-click on the drive where Windows 10 is installed and then click Properties.

Step 2: Under the General tab of Properties dialog, click Disk Cleanup button to let the tool calculate the amount of free space that you can free up by deleting unnecessary files.

NOTE: If you the Disk Cleanup button is not showing up, please refer to our restore missing Disk Cleanup button guide.

Step 3: When you see the following dialog, click Clean up system files button.

Step 4: Finally, check the box labelled Device driver packages and then click OK button.

Click Delete files button when you see the confirmation dialog to begin deleting old drivers from Windows 10. Simple as that!

You can also free up space by deleting Windows Update cache in Windows 10.

The following components are necessary to install and support a device on a Windows operating system:

The device itself
If you plan to design and build a new device, follow industry hardware standards. When you follow these standards, you are more likely to have a streamlined development process as well as lower your support costs. Not only do test suites exist for such devices, but, in many cases, generic drivers exist for standard types. Therefore, you might not have to write a new driver.

The driver package for the device
A driver package includes all the software components that you must supply to ensure that your device is supported with Windows. Typically, a driver package contains the following components:

• Driver files

• Installation files

• Other files

A brief description of each component of a driver package follows.

Driver Files

The driver is the part of the package that provides the I/O interface for a device. Typically, a driver is a dynamic-link library (DLL) with the .sys file name extension. Long file names are allowed, except for boot-start drivers. When a device is installed, Windows copies the .sys file to the %SystemRoot%system32drivers directory.

The software that is required to support a particular device depends on the features of the device and the bus or port to which it connects. Microsoft ships drivers for many common devices and nearly all buses with the operating system. If your device can be serviced by one of these drivers, you might have to write only a device-specific minidriver. A minidriver handles device-specific features on behalf of a system-supplied driver. For some types of devices, even a minidriver is not necessary. For example, modems can typically be supported with just installation files.

Installation Files

In addition to the device and the driver, a driver package also contains one or more of the following files that provide driver installation:

Device Driver Files In Linux

• A device setup information (INF) file

  An INF file contains information that the system-provided device installation components use to install support for the device. Windows copies this file to the %SystemRoot%inf directory when it installs the device. Every device must have an INF file.

  For more information, see Supplying an INF File.

• A driver catalog (.cat) file

  A driver catalog file contains a cryptographic hash of each file in the driver package. Windows uses these hashes to verify that the package was not altered after it was published. To ensure that the catalog file is not altered, it should be digitally signed.

  For information about how to sign drivers, see Signing Drivers for Public Release and Signing Drivers during Development and Test.

A driver package can also contain other files, such as a device installation application, a device icon, device property pages, and so forth. For more information, see the following topics:
