Things you didn't know, you never veered, but you change some settings within that can improve the speed of the camera.

Enter the start-run-regedit & quot; & quot; command.

Remind: If you modify the registry can cause a system crash, it is recommended that you back up the registry before modifying it.

If you are not very familiar with it, the best is to use & quot; & quot rabbit magic settings; & quot; Windows unexpectedly & quot; masters of to optimize the registry.

Regedit open registry

Windows registry is to help Windows control hardware, software, user environments and Windows interface of a data file, the registry contained in the Windows directory as two files system.dat and user.dat, have their backup system.da0 and user.da0. Through the Windows directory of the regedit.exe program can access the registry database. In the past, in earlier versions of windows (Win95 previously), these features rely on other system.ini and win.ini, and applications related to the .ini file.
In the windows operating system family, the system.ini and the win.ini file contains all the control functions of the operating system and application of information, the management of computer hardware and system.ini win.ini manage desktops and applications. All drivers, fonts, settings, and parameters are stored in the .ini file, any new programs will be recorded in the .ini file. These records will be referenced in program code. Because from win.ini and system.ini file size limit, the programmer to add auxiliary .ini file to use to control more of the application. For example, Microsoft Excel has a excel.ini file that contains the options, settings, default parameters, and other relationships to Excel is running properly. In the system.ini and win.ini in only need to point out the path and file name excel.ini.

Back in the Dos and the era, most Win3.x applications are using the ini file (initialization file) to store configuration information, such as setting the path environment variable. System.ini and win.ini in control of all the windows and the application's features and access method, which in a small number of users and a few applications to work very well. As applications of increasing number and complexity, you will need in the .ini file to add more parameters. So, in a changing environment, and the applications installed on the system, everyone will change the .ini file. However, no one in the delete after removing the application .ini file settings, so the system.ini and win.ini files the two will become larger and larger. Each additional content will lead to more and more slow system performance. And each application's upgrade such challenges: upgrade will add more parameters, but never get rid of the old settings. But there's an obvious question, a .ini file maximum size is 64KB. To solve this problem, software developers themselves start to support their .ini file, and then point to specific ini files like win.ini and system.ini files. So down multiple .ini file affects the system the normal access level settings. If an application's .ini file and win.ini file settings conflict, who is of higher priority?

The registry was originally designed as an application data file related reference documents, and finally expand for 32-bit operating system and application includes all the features of the dodo. The registry is a set of control operating system look and how to respond to external events work files. The & quot; & quot; events range from direct access to a hardware device to respond to specific user interface to your application to run, and so on. Registry since its purpose and nature of change is complex, it was designed specifically for the 32-bit applications work, the file size is limited to approximately 40MB. Use a powerful registry database to unified centralized management system hardware, software configuration, and other information to facilitate management, enhances system stability. The most intuitive one instance is why windows users of different can have their own personalized settings, such as wallpaper, a different desktop. This is achieved through the registry.

This shows that the registry (the Registry) is Windows9x/Me/NT/2000 operating system, hardware, device and client applications to work properly and to save the settings for the core & quot; & quot; database; it is a huge tree hierarchy of database. It records the user install the software on the machine and for each procedure of interconnected relationships; it contains the computer's hardware configuration, including automatic configuration of plug and Play device and have the device description, State property, as well as various kinds of status information and data, etc.BR>
Registry do?
The registry is for Windows95 WindowsNT and in all 32-bit hardware/drivers and 32-bit application design data files. 16-bit drivers cannot work under the WindowsNT, all devices are controlled by a registry, generally these are controlled through the BIOS. In Win9x, 16-bit drivers will continue to work on real-mode style device, they use the system.ini to control. 16-bit applications will work on NT or Win9x, their program still refer to the win.ini and system.ini files to obtain information and control.
In the absence of the registry, the operating system does not obtain the necessary information to run and controlled subsidiary of devices and applications and correctly respond to user input.

In the system registry is a record for 32-bit driver settings and location of the database. When the operating system needs to access hardware devices that use the driver, or device is a BIOS supported devices. No BIOS supported device driver must be installed, this driver needs is independent of the operating system, but the operating system needs to know where to find them, file name, version number, other settings and information, there is no registry on the device, they would not be in use.

When a user to run an application, the registry provides application information to the operating system, so that the application can be found, correct data file location is required, other settings can also be used.

Registry data and saved on default secondary file location information, menus, buttons, bars, window status and other options. It also saved a setup information (for example), install software, the software version number and date, serial number, etc. According to the installation of the software, it includes information differently.

However, in General, the registry control all 32-bit applications and drivers that control method is based on the users and computers, and not dependent on the application or driver, each registry parameters control the functionality of a user or computer. User capabilities may include desktop appearance and user directory. Therefore, the computer functions, and installation of hardware and software related, so a user entry is public.

Some programs have an impact on users, and some time on the computer but not for the personal settings, the same, the driver may be specified by the user, but in many cases, they are common in the computer.
