Step by step optimization of Windows XP (2)

Who wouldn't want to make their computer run faster? Undoubtedly, we can choose high-speed CPU, large memory, new motherboard, even updated graphics card, and replace it with new hardware. The speed will of course be raised. However, if the configuration is certain, we can increase the speed. ? Then we only start from the operating system and do some optimization processing.

In the previous article, we have already talked about how to reduce the hard disk space for Windows XP. Then the next step is to speed up Windows XP.

First of all, we start from the simple, for the lower configuration, or the speed of the friend, the first thing we need to do is to sacrifice the visual effect to improve the speed of the computer, right click on my computer, in Select the property in the menu, this time pops up the properties dialog box, we select the advanced page, we click on the settings in the performance of the first column, select the visual effects page, there are four options, which are the best settings for Windows to choose the computer, Adjust to the best appearance, adjust to the best performance, customize, this time we choose to adjust to the best performance just fine, then click OK to complete the setup. Then we then in the desktop display properties, we select the desktop page, set the background to none, that is, no background, because the desktop wallpaper will also occupy system resources. At this time, the appearance of our Windows XP is almost the same as that of Windows 98. Although it sacrifices visual effects, it greatly improves the speed of the computer. Here, my habit is to choose custom when setting visual effects, use visual styles on windows and buttons, and use shadows on icon labels on the desktop. Others are not selected, and finally Then set an image of JPEG or GIF as the wallpaper for the system. The smaller the size of the wallpaper, the better, so that our Windows XP looks relatively beautiful and also speeds up.

Although Microsoft has optimized the system for Windows XP, there is still a lot of hands-on space for us to optimize. First, we will optimize the system from the registry.

First of all, we briefly introduce the registry registry is a huge database for storing various configuration data of computer hardware and software. The registry records the software installed by the user on the computer and the related information of each program. Users can adjust the running performance of the software through the registry, detect and recover system errors, customize the desktop, and so on. The user can modify the configuration, which can be easily done by using the Registry Editor and clicking the mouse. The system administrator can also complete remote management of the system through the registry. Therefore, the user has mastered the registry, that is, he has mastered the control of the computer configuration, and the user only needs to use the registry to adjust the working state of his computer to the best.

We need to modify the registry, then you need to use the registry editor, Windows XP comes with the registry editor, we open it, modify the registry, so as to optimize the system, open Start menu, select Run, type regedit Click OK, this time we see the dialog box is divided into left and right columns, the left column is the directory, under my computer there are five items HKEY_CURRENT_USER, HKEY_USERS, HKEY_LOCAL_MACHINE, HKEY_CLASSES_ROOT, let's first A brief look at their HKEY_CURRENT_USER contains the root directory of the configuration information of the currently logged in user. The user's folder, screen color, and control panel settings are all stored here. This information is associated with the user's profile. This item is sometimes abbreviated as "HKCU". HKEY_USERS contains the root of all user profiles on the computer. HKEY_CURRENT_USER is a child of HKEY_USERS. HKEY_USERS is sometimes abbreviated as "HKU". HKEY_LOCAL_MACHINE contains computer-specific configuration information (for any user). This item is sometimes abbreviated as "HKLM". A subkey of HKEY_CLASSES_ROOTHKEY_LOCAL_MACHINE\\Software. The information stored here ensures that the correct program can be opened when opening a file using Windows Explorer. This item is sometimes abbreviated as "HKCR". Starting with Windows 2000, this information is stored under HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER. The HKEY_LOCAL_MACHINE \\Software\\Classes entry contains default settings that can be applied to all users on the local computer. The HKEY_CURRENT_USER \\Software\\Classes entry contains settings that override the default settings and apply only to interactive users. The HKEY_CLASSES_ROOT entry provides a registry view that combines information from the two sources above. HKEY_CLASSES_ROOT also provides this merged view for programs designed for previous versions of Windows. To change the settings of an interactive user, you must make changes under HKEY_CURRENT_USER \\Software\\Classes instead of under HKEY_CLASSES_ROOT. To change the default settings, you must make changes under HKEY_LOCAL_MACHINE \\Software\\Classes. If an item is written to an item under HKEY_CLASSES_ROOT, the system stores the information under HKEY_LOCAL_MACHINE\\Software\\Classes. If you write a value to an item under HKEY_CLASSES_ROOT and the item already exists under HKEY_CURRENT_USER \\Software\\Classes, the system stores the information under the previous registry key instead of HKEY_LOCAL_MACHINE \\Software\\Classes. HKEY_CURRENT_CONFIG is a subkey of HKEY_LOCAL_MacHINE \\Software. The information stored here ensures that the correct program can be opened when opening a file using Windows Explorer. This item is sometimes abbreviated as "HKCR". Starting with Windows 2000, this information is stored under HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER. The HKEY_LOCAL_MacHINE\\Software\\Classes entry contains default settings that can be applied to all users on the local computer. The HKEY_CURRENT_USER \\Software\\Classes entry contains settings that override the default settings and apply only to interactive users. The HKEY_CLASSES_ROOT entry provides a registry view that combines information from the two sources above. HKEY_CLASSES_ROOT also provides this merged view for programs designed for previous versions of Windows. To change the settings of an interactive user, you must make changes under HKEY_CURRENT_USER\\Software \\Classes instead of under HKEY_CLASSES_ROOT. To change the default settings, you must make changes under HKEY_LOCAL_MACHINE \\Software\\Classes. If an item is written to an item under HKEY_CLASSES_ROOT, the information is stored under HKEY_LOCAL_MacHINE \\Software\\Classes. If you write a value to an item under HKEY_CLASSES_ROOT and the item already exists under HKEY_CURRENT_USER \\Software\\Classes, the information is stored under the previous registry key instead of under HKEY_LOCAL_MacHINE\\Software\\Classes.

When we open the left column folder, what appears in the right column is called the key value. What we want to modify is the right key. Values, key values ​​are divided into the following categories: binary value (REG_BINARY), DWORD value (REG_DWORD), expandable string value (REG_EXPAND_SZ), multi-string value (REG_MULTI_SZ), string value (REG_SZ), binary value (REG_RESOURCE_LIST ), binary value (REG_RESOURCE_REQUIREMENTS_LIST), binary value (REG_FULL_RESOURCE_DESCRIPTOR), none (REG_NONE), link (REG_LINK), QWORD value (REG_QWord), we introduce the role of these key values.

binary value (REG_BINARY): raw binary data. Most of the hardware component information is stored as binary data and displayed in hexadecimal format in the Registry Editor.

DWORD Value (REG_DWORD): Data represented by a 4-byte long (32-bit integer) number. Many of the parameters for device drivers and services are of this type and are displayed in the Registry Editor in binary, hexadecimal or decimal format. The associated values ​​are DWORD_LITTLE_ENDIAN (the least significant byte is at the lowest bit address) and REG_DWord_BIG_ENDIAN (the least significant byte is at the highest bit address).

Extensible string value (REG_EXPAND_SZ): A variable-length data string. This type of data includes variables that are resolved when the program or service uses the data.

Multi-String Value (REG_MULTI_SZ): Multiple strings. A value that contains a list or multiple values ​​that a user can read is usually this type. Each entry is separated by a space, a comma, or other mark.

String value (REG_SZ): A text string of fixed length.

Binary Value (REG_RESOURCE_LIST): A series of nested arrays that store a list of resources used by a hardware device driver or a physical device it controls. This data is detected by the system and written to the \\ResourceMap tree and displayed as a binary value in hexadecimal format in the Registry Editor.
Binary value (REG_RESOURCE_REQUIREMENTS_LIST): A series of nested arrays used to store a list of possible hardware resources available to the device driver or a physical device it controls. The system writes a subset of this list to \\ResourceMap tree. This data is detected by the system and displayed as a binary value in hexadecimal format in the Registry Editor.

binary value (REG_FULL_RESOURCE_DESCRIPTOR): a series of nested arrays, for storing a list of resources used by the physical hardware devices. This data is detected by the system and written to the \\HardwareDescription tree and displayed as a binary value in hexadecimal format in the Registry Editor.
None (REG_NONE): There is no specific type of data. This data is written to the registry by the system or application and displayed as a binary value in hexadecimal format in the Registry Editor.

Link (REG_LINK): A Unicode string that names a symbolic link.

QWORD Value ( REG_QWord ): Data represented by a 64-bit integer number. This data is displayed as a binary value in the Registry Editor and was originally used in Windows 2000.

After understanding the simple situation of the registry, we started our optimization action. It is recommended that users who have no experience in registry modification should back up before modifying. The registry, the specific method is as follows: After we run regedit, pop-up window, the simplest backup method is to click the right mouse button on my computer (as shown)

We click export, At this time, a new dialog box will pop up, as shown in the figure

In the following export scope, we select all, then enter a file name above, select a path, click Save, and we will complete the registration. Backup of the table, after we accidentally modify the error, we can import the backup registry into the system, which will restore the previous
