How to save memory in Windows XP

Now we have made a big difference. Memory In this age, many people upgrade their memory to over 1 GB. However, with the enhancement of functions, many software accounts for more and more system resources. The rapid changes will make us overwhelmed. What should I do at this time? Next, let's talk about how to effectively save memory and make reasonable use of every resource in the Windows XP operating system.

Let's take a look at the following. We can all use those settings to save memory.

Optimize memory data

In Windows, the more data in the resident memory, the more memory resources you need. Therefore, do not set too many shortcut icons on the desktop or in the taskbar. If the memory resources are insufficient, consider using as few programs as possible that reside in the background. Do not open too many files or windows when operating your computer. After using the computer for a long time, if the computer is not restarted, the data arrangement in the memory may be chaotic, resulting in a decline in system performance. Now you have to consider restarting the computer.

Enable disk write Cache

Right-click my computer and choose Properties> hardware to open the device. Management Find the currently in use hard disk, right-click to select Properties. On the "Policy" page of the hard disk attribute, enable "Enable write cache on disk" (1 ).

 

Figure 1

This option will activate the hard disk write cache, thus improving the read/write speed of the hard disk. However, after enabling this function, a sudden power failure on the computer may cause irreparable data loss. Therefore, it is best to enable this function again when there is a UPS. Of course, if you do not perform any important data processing work when using a computer, it does not matter if you do not use UPS. This function will not cause too much loss to the system.

Disable unnecessary services

If you do not have a printer in your house, you can disable the "Printer Spooler" service. If you do not perform tasks on a regular basis, disable the "Task Scheduler" service. For most people, "Remote Registry" is useless and can be disabled. Below is the list of all the optimized services above. I marked the optimized areas with red circles.

Enable ultra MDA

In Device Choose "Basic/secondary ide controller" in the ide ata/atapi controller and right-click and choose "properties" to go to the "Advanced Settings" page. The most important settings here Project It is the "transmission mode". Generally, select "DMA (if available )".

Monitor memory

No matter how large the system memory is, it will always be used up. Although there is a virtual memory, the read/write speed of the hard disk cannot be compared with the memory speed, so when using the memory, you must always monitor the memory usage. A system monitor is provided in Windows to monitor memory usage. Generally, if only 60% of the memory resources are available, you need to adjust the memory. Otherwise, the computer's running speed and system performance will be seriously affected.

 

 

Configure recovery options

When a fatal error occurs during Windows XP running Memory The snapshot is saved as a file for system debugging. For most common users, this file is of no use and affects the performance of the virtual memory. So close it.

Right-click my computer, select Properties> advanced, and click set under performance, select the "advanced" page in "performance options. Here is a "memory usage" option. If it is set to "system cache" (2), Windows XP uses about 4 MB of physical memory as the read/write Hard Disk In this way, the data exchange speed between physical memory and virtual memory can be greatly improved. By default, this option is disabled. If the computer has enough physical memory, such as MB or more, you 'd better enable this option. However, if the physical memory is tight, the default option should be retained.

Set page files

Now return to the "virtual memory" Setting dialog box, select the Custom size, and set the "initial size" and "maximum value" according to the above calculation results ". Here, we set the "initial size" to 91 m, and the "maximum" to 200 m. Insurance .

Change the location of the page file

The main objective is to maintain the continuity of the virtual memory. Because the hard disk reads data by the head on the magnetic material, and the page files are stored in different areas on the disk, the head is about to jump, which is not conducive to improving efficiency. In addition, the system disk has a large number of files, and the virtual memory is definitely not continuous. Therefore, you need to place the files on other disks. To change the file location on the page, right-click my computer and choose Properties> advanced> Performance Settings> advanced> change virtual memory. Drive Select the position you want to change. It is worth noting that after a page file is moved, the original file must be deleted (the system will not delete it automatically ).

Change the page file size

After the location of the page file is changed, we can adjust its size. During Adjustment, do not set the maximum and minimum page files to the same value. Because the memory is usually not "full", when the internal storage reaches a certain level, it will automatically put some data that is not used for the time being into the hard disk. The larger the smallest page file, the lower the proportion, and the slower the execution speed. The maximum page file is the limit value. Sometimes many programs are opened, and the memory and the minimum page file are full. This will automatically overflow to the maximum page file. Therefore, it is unreasonable to set the two to the same value. In general, the minimum page file is smaller, so that more data can be stored in the memory as much as possible, the higher the efficiency. The maximum page size is larger to avoid "full.

Fragment of page files

After the file data has been stored on the hard disk for a long time, fragment will naturally generate. To maintain or improve the hard disk Work Efficiency, we should perform a fragment for the hard disk from time to time. The so-called virtual memory is actually a data file on the hard disk. Should the virtual memory be organized like a common file?

The Windows system processes page files (Virtual Memory) in a way different from general files. In contrast, page files are less fragmented than normal files, and it is usually unnecessary to organize page files. In fact, when Windows XP is used for disk fragment, page files are not involved.

Although Windows does not sort out page files, in fact there are fragments of page files. Friends who are pursuing perfection may still want to fragment page files. Try the following method:

Right-click the "my computer" icon on the desktop and select "properties" from the function menu that appears later ". In the system attribute settings window, click "advanced"> "performance"> "Settings"> "advanced"> "change ", in the subsequent "Virtual Memory" settings window, select "non-paging files. Click "set" to exit and restart the computer.

Disable page files

If you have a memory of more than MB, the page file will no longer function obviously, so we can disable it. The method is to go to the Registry Editor "hkey_local_machinesystemcurrentcontrolsetcontrolsession ma-nagermemorymanagement" and set its value to "1" in the "disablepa-ging executive" option.

Clear page files

There is a "clearpagefileatshutdown (clear page files when shutdown)" at the same location, set this value to "1 ". The "clear" page file mentioned here does not mean that pagefile is completely deleted from the hard disk. SYS file, but to "clean" and organize it, so as to better use the virtual memory to prepare for the next Startup of Windows XP.

Adjust the cache area size

You can set the ratio of the system to use the cache in the "Main usage of the computer" tab. If the system has a large amount of memory, you can select "network server". In this way, the system uses a large amount of memory as the cache. In CD -In the ROM label, you can directly adjust the amount of memory used by the system as the high-speed cache for reading and writing the CD-ROM disc.

Impact of system themes

Speaking of occupying system resources, we have to mention the system topic. Although a beautiful system topic can bring visual enjoyment to our windows, it also consumes a lot of our system resources, the following describes how to avoid occupying too much resources for a Windows topic:

We can set ****. copy the tsk desktop topic file to the root directory of your memory card, and create a folder named my documents files. This means that no memory resources are occupied. You can switch to the "today's topic" folder, which is also convenient. Management .

Release Memory Space

If you find that the system does not have much memory, pay attention to releasing the memory. The memory is released from the memory. The simplest and most effective way to release memory is to restart the computer. In addition, it is to close programs that are not currently in use. Note that if image data is stored in the clipboard, a large amount of memory space is required. At this time, as long as you cut a few words, you can overwrite the original image on the clipboard in the memory to release the large amount of memory it occupies.

Improve performance of other system components

The performance of other computer components has a great impact on memory usage, such as bus type, CPU, hard disk, and memory. If the memory size is too small and the displayed data volume is large, it is impossible to increase the running speed and system efficiency with more memory. If the hard disk speed is too slow, it will seriously affect the work of the entire system.

Disable Automatic update"

"Automatic update" is a new feature launched by Windows XP to help users upgrade the system. This feature can be used when Microsoft releases system upgrade patches or system security patches, automatically reminds users to upgrade their systems. If you do not set this system, you will often start to download the upgrade package on your own, wasting our system resources also occupies our network bandwidth. Therefore, we disable the "Automatic Upgrade" function and change it to "manual upgrade ".

For details, right-click "my computer", click Properties, click "Auto Update", and select "Disable auto update" in the "Notification Settings" column. I will update the computer manually.

Disable "System Restore"

The System Restoration function is a very imaginative idea of Microsoft. However, Microsoft has not been able to achieve this idea very well. Therefore, the system restoration function can only be tasteless, and it is a pity that it is useless. For users, it does not have much effect, so we decided to disable it to save memory. For details, right-click my computer and click Properties. The System Properties dialog box is displayed. Click System Restore. Drive Turn off the system restore option.

Disable Remote Desktop

This feature is familiar, because Windows 2000 server has a terminal service to do the same thing. We can find that Microsoft's policy, in the Windows 2000 era, this function is only available in Windows 2000 of the server version, and its name is also very professional. It is called terminal service. I am afraid the average user does not know what this function is. In Windows XP, this function was added to Windows XP Home and professional versions, and its name was changed to "Remote Desktop ". As the name suggests, this function allows you to allow others to access your desktop on another machine. It can be said that this function is useful in a network environment, such as a LAN. For example, if you have a problem, you can ask a colleague for help. Instead of getting to you, you can directly access your machine through remote desktop to help you solve the problem. But at home, there is usually only one computer, and this function is redundant, So Microsoft has given it a new function called "quick User Switching ", that is, you do not need to cancel your user so that another user can register as another user to use your computer. I personally doubt its practical value. Most people do not have the concept of a user when using a computer, so it is useful for users. So I suggest you turn it off, otherwise you will waste the memory if you don't use it.

Disable the automatic sending error feature.

You must have such an experience in Windows XP. Once a program ends abnormally, the system automatically jumps out of a dialog box asking if you want to send an error to Microsoft, this is the "auto-send error" function in XP, which is of no use to us. So why make it occupy your memory? Therefore, we should turn this feature off without hesitation. Right-click "my computer", click Properties, click "advanced"> "Error Report", and select "Disable Error Report" (3 ).

Disable unnecessarySpecial effects

The operating interface of Windows XP is indeed very nice-looking, behind which is a lot of consumption Memory In terms of speed and beauty, we prefer to select the former, right-click "my computer", click Properties, and click "advanced". In the "performance" column, click "Settings" and "Visual Effects". Here, all the special appearance settings are disabled, and we can save a huge amount of memory.

Disable "Internet time synchronization"

"Internet time synchronization" means that your computer clock is synchronized once a week with the Internet time server, so that your system time will be accurate, but this function is of little use to us, it may also cause a crash. So we need to turn it off.

Click Start> Control Panel> date, time, language, and Region options, and then click Date and Time> Internet time ".

Disable redundant services

Windows XP and Windows 2000 can be used as HTTP servers, email servers, and FTP servers. Therefore, many services are started whenever Windows XP is started, there are a lot of services that are useless to common users, so turning them off is a good choice.

Clear clipboard content

Clipboard is a temporary storage area in memory, used to store information cut or copied by various applications. If an image or a piece of text is stored in the clipboard at that time, it occupies a considerable amount of memory, which may lead to insufficient memory, therefore, as long as the image or text in the clipboard is eliminated, memory insufficiency may be solved. To clear the clipboard content, click Start, program, attachment, and clipboard view program to open the clipboard view program window, click the "delete" command in the "edit" menu, and then click the "yes" button. You may think this is a little troublesome, so you may wish to replace the image or text in the clipboard with a very small amount of content, such as a space. For example, if you are using word to edit a document, you can select a space in the document and click the "Clipboard" button on the commonly used toolbar, this space replaces the original image or text in the clipboard, which can also save memory.

Close unnecessary windows

You open multiple windows, that is Sports Multiple programs consume more memory. At this time, you can close the window that is not used for the time being, and close the functions of unused programs (such as the status bar, ruler, and taskbar) to save memory.

Reserve hard disk space as extra memory

Right-click "my computer" on the desktop, and then click "properties" to open the "System Properties" dialog box. In this dialog box, click the "performance" tab, and then click the "virtual memory" button to check Management (4), and then click OK.

 

Figure 4

Do not load programs in windows.

First, check which programs are automatically loaded during Windows Startup by clicking the start button, pointing to the program, and then to start ", the menus listed here are the programs automatically loaded when Windows is started. Remove unnecessary programs, restart the computer, and save memory. The specific deletion method is as follows:

(1) Start "Resource Manager" and find the C: windowsstart menuprograms "start" folder.

(2) select Programs and shortcuts that do not require Windows automatic loading, and click the "delete" command in the "file" menu. The confirm deletion dialog box is displayed.

(3) Click "yes" in the confirm deletion dialog box.

Virus detection and removal

Maybe your computer is infected with a computer virus, and the memory is insufficient because the virus is being blamed. Eliminating the virus can also solve the problem of insufficient memory. Of course, the method is to use a good Anti-Virus Software Scan and kill viruses.

How to Set virtual memory

1. The so-called virtual memory is to use part of the hard disk space as the memory when your physical memory is insufficient, but because the hard disk transmission speed is much slower than the memory transmission speed, therefore, using virtual memory is less efficient than physical memory. You should adjust the actual value multiple times. A large number of fragments are generated when the virtual memory is too large, which seriously affects the system speed. If the virtual memory is too small, the system will prompt you that the virtual memory is too small.

2. In general, Windows can automatically allocate and manage virtual memory. It can dynamically adjust the virtual memory size based on the actual memory usage.

3. Custom virtual memory. Generally, the default virtual memory size is to take a range value. It is best to give it a fixed value so that it is not easy to generate disk fragments, the specific value depends on your physical memory size. The physical memory is 768 MB. The virtual memory can be set to 1024 MB or MB.

4. The specific steps are as follows: Right-click "my computer" → properties → advanced → Performance Settings → advanced → virtual memory change → select virtual memory (page file) storage partition → Custom Size → determine the maximum and minimum values → settings → OK.

5. There must be sufficient space for partitions stored in virtual memory (page files) and insufficient hard disk resources, resulting in insufficient virtual memory.
