The steps of updating driver first introduce how to update the damaged Qu driver. If there is no backup driver (including Dong CD-ROM), you can use the driver wizard software to update it automatically. Dan, I have a backup driver. Of course, it is better to install the original one. Shou first right-click from this pc -> Management -> Open "Set Bei Manager". Two device drivers are not installed properly. Please select one of Ze to update. 2 If you use the manual Geng new driver, there are two options. One is that the system automatically searches for the driver to install in the Zai computer, generally searching for the Windows\System32\driversWen folder or the folder backed up by the system. The other is the driver that Zi has backed up, or the driver CD that comes with the purchase. What is taken in Zhe is backup. In the following interface, select "Browse Lan Computer to Find Driver Software". 3 Lai To reach this interface, you need to manually specify the location where the driver files are stored. Before specifying, you should check the item "contain subfolders" Zhe, and then press the "browse" button. In your own magnetic Pan, expand the folder paths in turn, find and select the folder where the Qu files are stored, and then press the "Open" button. Ti indicates: Install the backup driver manually, and select a folder (the driver file is included in the Qi) instead of a file. After the 4 Ba path is loaded into the edit box, click Next to start installing the driver manually. However, after a while of installation, Dan opens a prompt window "Windows encountered a problem when installing the driver software with Bei, and the third party INFBu contains digital signature information", which means simply that the driver Cheng sequence installation failed because there is no digital signature. How can Ru solve this problem? The following steps are introduced in detail. Qi dynamic disable driver mandatory signature Although Microsoft engaged in Ge driver digital signature, it also gave Hui, a machine that didn't join, the disabled driver mandatory signature. How can She set this disabled driver mandatory signature? This is the content introduced by Yao below. First, click the "Start" icon in the lower left corner of the Kai taskbar on the desktop of Win1, and select "She" in it. Enter the settings window, find the item "update and security Quan", and open it. At that time, I searched for it for a long time, but I didn't send the item "update and security" to Xian. Later, I found out that Yao could only see it when it was pulled to the scroll bar, and this item was at the bottom. Ha, Zai, smart people sometimes get confused, mainly because the scroll bar color of Win1Xi system is very light and it is difficult to see at all. In the Dao update and security window, first select "Recover Fu" in the left option, then go to the right window of recovery and select the "Restart Now" button of "Gao Start". Why does Yao restart the computer immediately? Originally, Xu, which disabled the driver's mandatory signature, can only be set in the advanced mode of boot. After An clicks the restart button immediately, you will enter a blue window. There are some options in Zhe, including continuing, troubleshooting, and turning off Nao. Because the system version is different, the options may be different. Dan is the same. You must choose the "Troubleshooting" Yi item, and then you can enter the high Ji setting window when you restart the computer. Enter the troubleshooting window, which is simpler than Shang's interface. There are only two options, one is "Reset Ci Computer" and the other is "Advanced Option". To reset this pc, Shi asks you to save important disk files first, and then reinstall WindowsXi system. This is definitely not what we want, so we know Dao, and we have to choose "Advanced Option". After entering the Gao-level options window, you have to make a choice. It's really troublesome for Window1Jin to sign by drivers. There are many options here, such as System Restore, System Image Recovery, Qi Dynamic Repair, Command Prompt, Startup Settings and Hui to Back to Previous Version. These are all in Chinese, and their functions are easy to understand without explanation. Here, you Chang choose directly. There is also a startup settings window, which still Rang people can't live. Why does a setting have to go through so many settings? Think of XP system, how simple it is? Is the version of Microsoft Sheng just to make users toss more? Helpless. In fact, in this Ge interface, don't choose anything, just press "Restart" and you will get it. It's really helpless to go through such a procedure. Qi actually doesn't really restart the computer, just set a Xia preset, and it is really restarted here. After the restart, enter the black advanced options interface of Ru, with different versions of Win1, and Ye has a blue interface. In this interface, find and select Ze "Disable driver compulsory signature", and then press EnterHui,://3Rxing/Question/34B 178FE9C84577. Tip: It turns out that the cursor is signed by driver in Jin, because the cursor Xiang can't be seen clearly when taking pictures. In order to make everyone see it clearly, the cursor Yi is put on "Start Windows normally". What should Jin do after signing with the driver? If Hou is disabled, he will automatically re-enter the Windows system. However, Hou will go back to the device manager, find the device to be updated, right Jian, and update the driver. When you start the driver update Hou, and then follow the steps in 1-4 above to select the driver file Jia, a "Windows An All" warning window will pop up when installing. At this time, select the item "Always install this Qu driver software". The installation starts immediately, And an installs the driver, which generally doesn't take too Jing. After the installation is completed, Hui pops up a page, prompting that "Windows has successfully updated the driver file", which even shows that the driver Cheng sequence is successfully installed and the problem is successfully solved. Tip: Qi real Win8 also has such a problem, and its setting method is similar to Yu's; Win7 disables the driver's digital signature and changes the Jian list. You can set it directly by pressing F8 to enter the advanced mode. Ke refers to the following two articles. 22Win8 update Qu prompt third party inf does not contain digital signature information 21Ru How to enable the disabled driver signature of Win7 system How to solve the problem that INF does not contain digital signature information < P > Great God, I changed my computer from Win8 to win7Shi today,,, you still change win1, and the win1 driver cannot be installed. Some applications can't be used, and the system settings are limited
Because the new version of win1 operating system has become very strict with the digital signature of driving Cheng sequence, some drivers have not been updated, and the third party has already made De drivers with strong compatibility and sent them to the Internet for download. Although this drive Ming is stable and highly compatible, it can't be installed without digital signing. Try the following Cao (no signature): "Start menu"-"She home"-"Update and security"; Click "Restore" on the left side of the update and security Quan interface, and then restart at the right window point Ji; After restarting, click Troubleshoot on the "Select an option" Jie; Open the troubleshooting interface, and Jie tries to click "Advanced Options"; Click "Advanced Options" Hou, then click "Start Settings", then click "Restart", and then restart the computer by Ci; When the computer restarts, we Mian press F7 on the keyboard according to the prompt. Tong, after the above operation, we closed the driver digital certificate Jian of Microsoft.
