Want to know why you run low? Driven problems do not ignore

The role of the driver is to make the system aware of these hardware and let them function properly as required. However, if you do not really understand the driver, you may lose a lot of performance. This is also an important reason why some computers have the same configuration, and the results are lower than others.

1. What is the WHQL driver

Drivers now have a tag called WHQL. This WHQL is an abbreviation for Microsoft Windows Hardware Quality Lab. Chinese means Windows Hardware Device Quality Lab (certification). It is mainly for Windows operating system compatibility testing. This lab is mainly engaged in testing the compatibility and stability of computer hardware products, drivers, and Windows operating systems. If it passes the tests, it proves that this product is 100% compatible with the Windows operating system, so that the computer system can achieve better stability. Sex. The biggest feature of this category is the high stability and compatibility with Microsoft operating systems. Under normal circumstances, the user's preferred driver is the best version certified by Microsoft WHQL.

2. Is there a difference between the driver provided by the system and the driver provided by the manufacturer?

The drivers that come with the Windows system are 100% certified by the WHQL driver. This is a collaboration between Microsoft and related hardware vendors. Stability is certainly beyond doubt. However, this driver comes at the expense of "sacrificing" functionality, even at the expense of performance. The reason is that for Microsoft, the driver that comes with the system must ensure maximum compatibility and stability, and there is almost no consideration of functionality and performance. In particular, sound cards and video card drivers often lack a lot of features.

In the latest Windows 10, this situation has changed, apparently Microsoft has strengthened collaboration with hardware vendors, drivers are updated more frequently (relative to the past), and at the same time try to provide more extensive features.

3. Is driving really newer the better?

Do not know if the little friends pay attention to not, the system comes with a very old driver, it is almost an original version. Some people may ask, is it better to drive the program as new as possible, it is best to keep the time updated, so as to ensure the maximum performance and function of the system?

For Xiao Bian, this is incorrect. For example, after the graphics card is released, the initial driver update is gradually improving, improving the graphics card's features, performance, and even optimization of a new game. This period is generally a positive driver update. When this product is replaced especially when the time is longer, the difference between the old and new graphics cards will be more and more technical, resulting in the driver is difficult to adopt a consistent performance gain standard, eventually the new driver can only give up those old graphics card, and the new version of the driver sometimes It will also add some features that were not supported by earlier hardware, leading to the performance of early hardware that could not keep up with the latest drivers, although this is not the vendor’s intention. So sometimes it's important to back up your own drivers, not to catch up.

For Xiao Bian, the best choice for drivers is WHQL official certification, and it is the driver that is released within half a year and one and a half years after the product is released. Find the one with the best performance and leave a backup copy.

4. How to install the driver without certification?

Finally, there are some very exceptional exceptions, some products are either too old, there is no new version of the system's adapter driver, or some very special hardware, you must use a non-certified driver, or can not be installed.

In the Device Manager, find the device you want to install manually, and double-click the pop-up properties dialog box to switch the tab to the "Driver" column.

At this time, click Update Driver, and select “Browse my computer for driver software” in the pop-up page to install it manually.

Locate the driver directory to be installed. Double-click to select it. The system will pop up a dialog box stating "Unable to verify the publisher of this driver software". At this time, select "Moderately install this driver software" to force the driver to be installed.
