Solve the problem of incorrect installation of win8 driver

For Win8, for users, the most worry is not Win8 download, not Win8 installation, nor Win8 activation. The most worrying is the Win8 compatibility, which is whether the software and hardware used now can be used on Win8. This post will explain the problem of incorrect or uninstalled Win8 driver installation.

This post is roughly divided into three parts. First, what is the driver? What are the consequences if the driver is not installed? Then, when installing the Windows driver on the old system, how to solve the driver installation in win8 is incorrect. Or not installed; finally said in the new system, how to solve the Win8 driver installation is not correct or not installed.

First, the driver and its role

A lot of times we can hear the saying that the first step is to install the driver after installing the system or see a lot of people on the Internet asking for a certain A kind of hardware driver. So what is the driver?

The full name of the driver is the device driver (English: device driver), which is a driver that allows high-level computer software to interact with hardware. This program creates a hardware and hardware, or hardware and software communication interface, through the bus (bus) or other communication subsystem (subsystem) on the motherboard to form a connection mechanism with the hardware, such a mechanism makes the hardware device (device The exchange of data on it is possible.

The above is a standard statement. It is not very easy to understand. I will give an example here. Due to the limitation of the level, it may not be appropriate. Here we compare the files on various computers to hardware. We need to read the information in these files and we must use software to interpret them. These softwares are drivers.

Some netizens have to say, I don't have a driver, just plug it in. This is actually the driver that comes with the operating system itself, but it can only implement the basic functions, even the basic functions can not be achieved, just like the graphics card driver is not installed, the resolution of most computers will be unusual. Just like Win7, we can open docx, rtf, odt and other documents with WordPad without any software, but if the document is plain text or simple layout, it is better to say that if it is complicated layout, it will be chaotic and even garbled. .

This should be able to understand the role of the driver. So how do you know if the driver is installed? Very simple, open the control panel, click on the device and the printer, if there is a yellow exclamation mark in the device, it is basically a driver problem. Let's talk about what to do if you encounter a Win8 driver that is not installed.

Second, when the Windows driver on the old system is normal, the driver installed in Win8 is not installed correctly or not installed.

When the Windows driver on the old system is normal, the driver of win8 is generally used. It can also be installed normally. Here you can directly upgrade to win8 or use the old system DriverStore, both of which can be installed normally when Win8 drivers.

1, upgrade to Win8

This is XP, Vista, Win7, you can follow the tutorial section of the forum. But there are a few things to pay attention to when upgrading Win8:

1, only 32-bit upgrade to 32-bit, 64-bit upgrade to 64-bit.

2. Upgrade can use U disk installation, virtual CD-ROM installation, hard disk installation, etc., but all must be started under the premise that the old system has been started to upgrade.

3. Upgrading a 64-bit system requires more than 20G of disk space on the system disk, and 32-bit needs more than 16G. If the disk space is not enough, you can consider using EaseUS Partition Master and other software to allocate more partitions to the system disk. Considering that the modern application can only be installed on the C drive, it is recommended that the C drive allocate at least 40 G or more.

4, the upgrade program will automatically detect incompatible programs and require uninstallation. It is recommended to uninstall anti-virus software, shadow system, HIPS software, sandbox, etc., most of which are not compatible with Win8, even if compatible, It is also necessary to install another version.

5. When upgrading, there will be several places that will be slower, about 20 minutes slower than the new installation, but the time to install the software is actually faster.

2. Use DriverStore

The old worm should have heard of DriverStore, or drive backup. That's right here is the drive backup folder for that system. When we encounter the incorrect installation of the win8 driver, you can directly troubleshoot, select "Browse the computer to find the driver software" in the pop-up window, then enter or select the driver backup folder of the old system, Win8 will Automatically search for the driver and install it for hardware that does not have a driver installed. There are several ways to find the driver folder of the old system:

1. Copy the backup folder of the old system to another disk before you install the system. Windows system driver backup folder: %systemroot%, System32, DriverStore (since the forum blocked the backslash, so everyone changed the number to the backslash, which is the symbol to the left, the same below).

2. After the new system is installed, look for the backup folder of the old system in the folder that was backed up for the old system. This folder is in C:, Windows.old, Windows, System32, and DriverStore (using the C drive as the system disk). As long as the user installs the new system, the folder of the old system is not formatted.

3. Users who have formatted the old system disk during installation can use the system backup or the DriverStore folder in the Ghost backup. This requires the old system to back up the system after the driver is installed and restarted, and the backup file has been retained.

Use the DriverStore folder in the system backup, mainly to those who are accustomed to using Windows backup, Windows Backup will compress the C drive into a VHD format virtual hard disk file, assuming I am on August 23 Back up the system on the H drive, then the file should be under H:, WindowsImageBackup, cyk553312-PC, Backup 2012-08-23 071047. Double-click this file in Win8 to load it. After loading, the DriverStore looks for the Windows and System32 folders in the newly created hard disk partition. In addition, you can use the software such as diskgenius to load and extract virtual hard disk files.

Some users because the Windows Backup disk space occupied too much, so switch to Ghost backup. This can be opened with Ghost explore, open the Windows, system32 folder, copy the DriverStore under the folder.

④, if it is installed to a different disk partition or dual system, it can be found in the old system of direct drive backup folder on the line.

If you have not been backed up in the system before installing the new system, the old system will also be where the partition is formatted, it can only be solved by newly installed systems.

Third, the new system encountered Win8 driver is not properly installed or not installed solutions

Some users buy a computer is a DOS or Linux system, or is not carried out before the installation of the system system backup, the old system partition will be formatted, this time if there is a problem with Win8 driver how to solve it? Right-click on the icon

1, the use of troubleshooting

yellow exclamation mark in the device and the printer, select troubleshooting, windows will automatically search the drive in question, select automatically pop in Searching for driver software, the system will search for drivers for the problematic hardware in Windows update and automatically download and install.

2, use software to search for hardware drivers or download drivers to the official website

Windows update has collected quite a lot of hardware drivers, but there will still be a lack of hardware drivers, this time only Go to the official website of the computer manufacturer to find and download the driver, or go to the hardware manufacturer to download the driver, or use the driver life, driver wizard to download and install the driver. Ordinary users recommend using the third.

3, consider installing Win7

such as the question, if Windows update, computer manufacturer's official website, the driver's official website, driver life, driver wizard, etc. can not solve the driver problem, it is recommended to consider Install Win7 to ensure that the system and hardware are working properly.
