This article will tell you why you should delete useless drivers in the computer and how to make it.

1. How to Delete Useless Drivers?
In your computer, there are some old drivers that can easy to be unnoticed. If you
installed any new devices recently but are not working properly, or they often cause
computer crashes, then, you can consider deleting the old or unused device drivers
in your computer.
A computer accumulates a lot of applications, drivers and assorted files over time
that can quickly reduce performance to a crawl. Every time you add an important
device to your computer, a driver is needed to communicate with the software and
hardware. Many drivers are pre-installed on your computer for such basic items as a
mouse or keyboard. Adding a new printer or game will require installation of a driver
that matches your specific software and hardware package.
Getting rid of unneeded drivers is an important action, yet it can be quite
complicated. Unfortunately, drivers do not have a beeping locator signal that tells
you where all the files are located. Usually, during installation, a program will rapidly
list the different elements of the driver (not telling you where they are being
placed on your computer) until you see an "Installation is Complete" message. It is
wise to double-check to ensure that everything is properly installed.
Since drivers are specific software and hardware version, any time you upgrade or
make major changes to your computer, you may need to get rid of unneeded drivers.
For instance, when you buy a better printer, you might want to delete the old
printer driver. Flushing old drivers out is like flushing out old used oil from your car;
new oil will improve performance, ensuring that your system runs more efficiently.
Your computer will work better when it doesn't have unneeded and old accessories
and parts.

2. Driver’s parts are installed in many different sensitive "Systems" files. Most driver
installation does not provide a helpful or reliable list of the location of the driver
files. Over time, it is easy to lose track of where driver files are located, especially
if the files have been changed or moved.
A number of different types of files extensions - including .sys, .dll and .exe - are
used by drivers. Unfortunately, many of these files are not clearly labeled. If you
mistakenly delete the wrong one, you could seriously harm your computer.
Drivers accumulate over time, every time a new plug-in or device is added to a
computer a driver is also installed. Many bits and pieces that are essential to proper
functioning of the driver are located in disparate files.
Unneeded drivers slow down the performance of computers over time; computers
attempt to search for program portions that are incomplete or missing. It is like
hitting the gas when you are in neutral.
One way to get rid of unneeded drivers is to go into the Device Manager by
following the path: Control Panel > System > Hardware > Device Manager. There you
can right-click on different devices and select "Uninstall". It is good to check your
Device Manager from time to time to see what you have installed.
A large pile of old drivers can easily confuse the operating system. Some "generic"

3. drivers work with different programs and devices, but are not as optimum as a
"specific" driver. You will have better computer performance with specific drivers
tailored for your specific devices.
More experienced computer users can edit the "Windows Registry Key" in order to
delete unneeded drivers. Only experts should attempt this action. They should
backup the Registry before making any changes. Be careful, because irreparable
harm could result from an error in modifying this registry. Anyway, there is also
some special registry cleaner software to delete the unneeded drivers as well as
other unwanted files and virus in the computer easily.
