Good control of driving and troubleshooting system

New computers just bought, or the Windows system crashes, we often need to reinstall the system operation, but after the successful installation of the operating system, the most difficult thing for everyone is the system-driven problem. For many friends who don't often touch computers, may encounter the system to find unknown device prompts, such a hint not only let people look upset, and many people do not know how to deal with; When you follow the on-screen prompts, the system cannot find the driver for the device, simply click the Cancel button, The system can not successfully install the unknown device. In order to let the system trouble to eliminate more handy, this article deliberately summed up the following several tricks, to help everyone clever management system driver.

1, restore the Vista driver file

Many friends in their own computer space is small, less memory, forced to install the Vista system, installed the system, found that the system running speed and storage space are not satisfactory, the only way to these friends have to find ways to the Vista system "slimming" operation, Removed the system's list of self-contained drivers that were temporarily unavailable. Although such a "slimming" operation can save 1GB of disk space for a computer, but when a new device is installed in the Vista system, the system cannot install the correct driver for it, so can we just watch the new device and not use it? Actually, We just follow the operation, the "slimming" system with the driver directory back to the local computer, Vista system will be able to automatically install the new device driver, then we will be able to use the new device normally:

First of all, put the installation CD of Vista system into the physical optical drive of the local computer in the correct way, and click the "Start"/"Run" command in the system desktop, in the pop-up System Run dialog box, enter string command "cmd", click "OK" button, Access to the Vista system DOS command line work window;

Second, at the command prompt at the window, enter the string command "Imagex/apply F:\lrmcfre_cn_dvd\sources\install.wim", and then click Enter to perform a file decompression, where F:\lrmcfre_cn_dvd For Vista system installation CD-ROM directory;

Then open the Vista System's Explorer window, find the "filerepository" subdirectory in the extracted directory, and directly copy the contents below the subdirectory to the local computer's "C:\windows\system32\driverstore" folder, As a result, we will again encounter the unknown device prompts, only to install the driver path manually to the "filerepository" subdirectory.

2, delete invalid hidden drive

With very limited resources in the local system, we often remove invalid devices that are not available for a long time from the system. However, because of improper deletion, the driver files are left on the local computer, and if there are too many drivers for these invalid devices, it will not only consume a lot of valuable system resources. , which can drag the computer system running speed, but also easy to cause the computer system to appear all sorts of strange malfunction phenomenon. To make the Windows system run more smoothly, we can find ways to remove the invalid device drivers that remain in the local system from being clean. Because these invalid device drivers cannot be seen in the System Manager window of the local computer, we cannot remove the invalid device directly from the Device Manager window, but we can try to remove the invalid hidden driver by following the procedure:

First, right-click the computer icon in the desktop of the local computer system, perform the Properties command from the pop-up shortcut menu, open the Properties Settings window for the corresponding system, click the Advanced System Settings option on the left side of the window, and open the Advanced Settings dialog box for the system properties.

Second, click the Environment Variables button in the Settings dialog box, open the Settings page shown in Figure 1, click the New button, and in the new dialog box that appears, we set the variable name to "Devmgr_show_nonpresent_devices" and then change The value of the quantity is modified to "1" and the "OK" button is clicked to save the above set operation;
