Device drivers are special programs created by computer operating system developers and device manufacturers for allowing related applications and users to utilize particular hardware installed in a computer. This means the drivers are necessary for related active applications to issue its requests directly to a hardware device in order to produce the results required by the user.

Creating a device driver to be used in MS Windows requires the knowledge of high-end programming language and machine language.

In most cases, high-end programming languages are applications that allow the user to create a program using codes that a developer can understand. This includes programming languages like Visual Basic, Visual C, Perl, and so on.

Machine language is a program that uses codes comprehensible to a hardware device. An example of this program is the Assembly language.

These are necessary requirements for the creation of a working device driver. Listed below are the considerations programmers need to make before creating device drivers.

1. The device that the driver will be used on;
2. The operating system that will use the driver;
3. The built-in functions and features of the device.

A programmer initially needs to come up with a name of the device during device driver coding. The name must be short and can easily describe the type of hardware component the device driver will be used for. This means in case the driver will be used for a floppy drive, then the name "fd" will suffice, and if it will be for a storage device, then "sd" is the preferred name for it.

This should be followed by a prefix detailing the function of a set of codes such as fd_read() for codes that will open the functionality of a floppy drive and fd_write()containing syntaxes for allowing the user to change the configuration and settings of the device.

The programmer must take into consideration the device driver's ability to utilize the memory of the machine to initiate its functions. This is done during device driver coding. Every application or program installed and used in MS Windows use the memory (RAM and OS virtual memory) of the machine as the primary location for its execution. Depending on the size of the installed memory, the number of active programs may be limited. This means the programmer needs to code their device drivers in a way that it will not consume too much RAM and OS virtual memory to avoid possible kernel-based errors.

If you're looking for software that keeps all your device drivers updated, I personally recommend Uniblue's Driver Scanner.
