It is recommended to use the Optimizer to clean the system after a period of time.
XP slimming, lose weight daquan
First, make the system disk cleaner (you can guarantee the running speed of your computer in a certain program)
1. Enter: Control Panel-System-Advanced-Environment Variables.
2. Click TEMP-Edit in the user variable to change the long content list to D:\TEMP (you can change it to another disk as needed, but it is not the location of the system).
3. Same as above, change TMP to D:\TEMP. Because these things are the main internal factors that make your system disk expand rapidly, their properties are hidden and some friends can't find them:)
4. In System Variable, change TEMP and TMP to the above values.
5. Right-click My Documents-Properties-Destination Folder on the desktop, set Destination Folder Location, change it to D:\My Documents or D:\ My Documents (up to you), and then optionally move it.
This is very important. In fact, when our computer crashes, there are generally nothing important in the system disk, but all the useful things are in my document, so I don't have to worry about anything when I move it to a new place. Also, quite a few friends will not back up my document content in DOS mode (because the folder name is very long, it will be more troublesome if it is in Chinese).
6. Right-click Internet Explorer-Properties-General-Temporary Internet File-Settings-Move Folder-Select D:\ Temporary Internet File \ (if not, you can create it first, or you can use D:\TEMP or something, you have the final say)-OK.
7. System-Advanced-Performance-Settings-Advanced-Virtual Memory-Change-Select D or other non-system partitions-Customize the size-Enter the size m-set; Select C or the partition where the system is located-no paging file-Settings-OK to transfer the virtual memory to other hard disks.
Well, the world (system disk) is quiet:)
Note: I have adjusted the virtual memory, temp and tmp, but I changed it back when installing some software. If you change it, you must remember the original path. )
Second, lose weight for XP (if your hard disk is enough, you don't have to lose weight, because if you want to use one of the functions, there is no way.
1. Delete system file backup.
Sfc.exe/ Puji Cache
2. Delete the driver backup
The Driver.cab file (73mb) in the windows\driver cache\i386 directory.
3. Cancel the system restore (but remember to keep the system restore of the system disk. Turn it off if you don't want to use it. I'll keep it anyway:)
4. Delete the help file (minus 40 mb)
5. Delete the file under \WINDOWS\system32\dllcache (minus 200-300mb), which is a spare dll file.
As long as you copy the installation file, you can do it completely.
6. Install the tool software on the system disk, and install the application software on other hard disks. Special reminder: your FOXMAIL, QQ and other things must not be installed in the system disk. Once the system is finished, you are finished:) (This is also good for reinstalling the system.
7. Delete the input method that is not used under \windows\ime! (Japanese, Korean, Simplified Chinese Input Method, 84.5MB)
8. If you think you have the ability to handle some emergencies, then install xp with ntfs, which will save the hard disk itself. Don't pretend to be a hero or wait to cry.
Third, delete the nasty msn and windows messenger.
Go to C:\windows\inf\ and open sysoc.inf
Look up msmsgs = msgrocm.dll, okentry, msmsgs.inf, hide, 7, delete hide.
Change to msmsgs = msgrocm.dll, ocentry, msmsgs.inf,, 7, and then save.
Go to Control Panel-Add Delete Program, and you will have the option to delete it.
Fourth, let Dr Watson, an incompetent doctor in China, be laid off.
The doctor looks at the computer and only tells you what the symptoms may be (I don't think he knows what the symptoms are), but he won't tell you what the disease is. The most important thing is that he will never meet you. What's the use of such a doctor? It's better to let him be laid off than to let me be laid off:)
In the "start"->; Enter "drwtsn32" command in "Run", or "Start"->; "program"->; "attachment"->; "system tools"->; "system information"->; "tools"->; "Dr. Watson", call out Dr. Watson in the system, and only keep the option of "Dump all thread contexts" (otherwise, once the program goes wrong, the hard disk will be read for a long time, occupying a lot of space. If this has happened before, please find the user.dmp file, which can save tens of MB of space after deletion).
Unload useless dynamic links.
Fifth, deleting the resource manager often leaves useless dynamic links in memory. In order to eliminate this phenomenon, you can open the registry editor and set the key value: HKEY _ local _ machine software Microsoft Windows CurrentVersionXplorer Always Sun LoadDLL = dword:1,and this function will be turned off. Restart the computer.
Sixth, small hard disk users are blessed, and friends with burners can do the gho version of XP.
First of all, when xp is newly installed, it is about 1.5G, and the default hibernation and virtual memory files account for 3 10m. If these two files are closed, it can be reduced to1.2g; Delete two compressed packages 80m in c:\windows\dllcab (only to play the role of not putting the system disk every time) to1.1g; I also deleted 30m Japanese and Japanese dictionaries (I hate XXXXX), and deleted unnecessary fonts in C: \ Windows \ Fon (about 50m) to1g; Delete all contents in c:\windows\system32\dllcab, which is a copy of dll. 320m can be safely deleted, so it is reduced to 680m. There are other 250 million forgotten (a little much, Microsoft will be very unhappy when it knows), and interested friends can find it themselves. I heard that the minimum can be reduced to below 400 mm.
Be careful not to delete it wrong. This article is for reference only, please bear the consequences yourself.
Seventh, the software that completely slimmed down WINXP came out! ! You can uninstall any bundled component. Including IE. OUTLOOK, even Movie Maker, MSN and so on.
Here it is: XPlite
There are many download addresses, and here are two:
Pat compatibility], [compatibility 32], [ime compatibility], [compatibility 95], [module compatibility] and [embedding].
Second, hardware.
1, the Windows system automatically turns off the hard disk DMA mode.
Everyone should know the DMA mode of hard disk. PATA modes of hard disk are DMA33, DMA66, DMA 100, DMA 133, and the latest SATA- 150 has come out! Generally speaking, most people still use the hard disk in PATA mode, and the transmission speed of the hard disk in DMA mode is 2~8 times faster than that in PIO mode. DMA mode plays an important role in system performance. But you know what? Windows 2000, XP and 2003 systems sometimes turn off the DMA mode of the hard disk and automatically switch to PIO mode! This leads to the sudden decline of hard disk performance when using the above system. The most obvious phenomenon is that the system startup speed is obviously slow. Generally speaking, when a normal Windows XP system starts, the slider moving from left to right can start the system up to 2 ~ 4 times, but when this problem occurs, it may go 5 ~ 8 times or even more! Moreover, when operating the system, the hard disk runs slowly. When running some large-scale software, the CPU utilization often reaches 100%, which leads to a pause. When playing some large 3D games, the screen obviously stops. When the above problems occur, you'd better see if the DMA mode of your hard disk is automatically turned off by the Windows system. Check whether your system is turned on in DMA mode:
A. Double-click management tools, and then double-click computer management;
B. Click System Tools, and then click Device Manager.
C. expand the node "IDE ATA/ATAPI controller";
D. double-click your "main IDE controller";
E. click advanced settings.
When you see Device 0, the following transfer mode should be set to DMA (if available) and then set to Current Transfer Mode. If it is "super DMA mode (number, DMA33 is 2, DMA66 is 4, DMA 100 is 5, DMA 133 is 6)", then your system is normal. But if you set Super DMA Mode 6 before and didn't change it, now it's Super DMA Mode 4 or Super DMA Mode 2 or PIO Mode and you can't change it! Maybe the system turned off DMA mode by itself.
2. Whether the 2.CPU and fan work normally and whether there is enough refrigeration.
When the speed of the CPU fan slows down, the temperature of the CPU itself will rise. In order to protect the security of CPU, CPU will automatically reduce the running frequency, which will slow down the running speed of the computer. There are two ways to detect the temperature of the CPU. You can use the "finger test" method to test whether the temperature of the processor is hot, but it should be noted that this method must first unplug the power plug and then connect a ground wire to prevent static electricity from penetrating the CPU or even damaging the CPU. Another scientific method is to use a multimeter with a temperature sensor to detect the temperature of the processor.
Because the types and models of processors are different, the reasonable temperature is also different. But generally speaking, the temperature should be lower than 1 10 degrees. If the processor test is found to be higher than this temperature, check whether the fan in the chassis works normally.
3, the impact of USB and scanner
Since Windows tests every drive (including the optical drive) at startup, if a CD is placed in the optical drive, it will also extend the startup time of the computer. So if the computer is equipped with scanners and other devices, or the USB hard disk is connected when it is started, then try to disconnect them first to see if the startup speed has changed. Generally speaking, due to the slow speed of USB interface, the corresponding devices will obviously affect the startup speed of the computer, so you should try to connect USB devices after startup. If there is no USB device, it is recommended to turn off the USB function directly in BIOS settings.
4. Do you use disk compression?
Because "disk compression" may cause a sharp decline in computer performance, resulting in a slower system speed. So at this time, you should check whether "disk compression" is used. The specific operation is to click the right mouse button on "My Computer" and select the "Properties" option from the pop-up menu to view the properties of the drive.
5, the influence of the network card
As long as it is not set properly, the network card will obviously affect the startup speed of the system. If your computer is connected to the local area network, after installing the network card driver, the system will automatically get the IP address through DHCP by default, but most companies' local area networks do not have DHCP servers. Therefore, if the user is set to "automatically obtain the IP address", the system will constantly search for DHCP servers in the network at startup until it obtains the IP address or times out, which will naturally affect the startup time. Therefore, LAN users had better specify a fixed IP address for their computers.
6. Folders and printers * * *
Computers with Windows XP Professional Edition will also start very slowly. Sometimes, the system seems to give people the feeling of collapse. After logging into the system, the desktop does not appear, and the computer seems to stop responding. It will take 1 minute before it can be used normally. This is because after using the Bootvis.exe program, the Mrxsmb.dll file adds 67 seconds to the computer startup!
To solve this problem, just stop * * * sharing folders and printers: select Start → Settings → Network and Dial-up Connections, right-click Local Area Connection, select Properties, uncheck the check box before * * * sharing files and printers on Microsoft network in the open window, and restart the computer.
7. Improper configuration of system accessories
Some users often ignore some trivial matters when assembling machines, which leads to improper matching of computer accessories and speed bottlenecks. For example, some friends choose high-end CPU, but sound cards and the like all buy ordinary cheap goods. In fact, this is often not worth the loss. Because in this way, when the computer is running games and playing DVD, the sound card occupies high CPU resources, the data transmission speed is slow, or there is no hardware decoding at all, and software decoding is needed, which often leads to the pause of sound and even the intermittent operation of programs. For example, some friends have upgraded their machines. In the past, some parts of old machines, such as memory chips, were not allowed to be discarded and installed on new machines. However, due to the speed limitation of the old memory, new machines often have to slow down to adapt to it, thus reducing the performance of the whole machine and greatly affecting the overall running speed.
8. Hardware drivers
Many players are novices. They don't know much about hardware drivers. When installing Windows, they don't know how to install drivers. It's like cooking jiaozi in a teapot. Can not pour out, can not give full play to the performance of hardware, a great waste of resources. As we all know, the same hardware, different versions of drivers or drivers from different manufacturers often lead to huge differences in performance, not to mention no drivers. Take playing DVD as an example. Even if you are the most advanced TNT graphics card, if there is no driver installed, you will not use the acceleration function of any graphics card when playing DVD, but use software to simulate the acceleration, and the effect is naturally terrible.
9. Disconnect unused network drives.
In order to eliminate or reduce the number of network connections that Windows must re-establish, it is suggested to disconnect some unnecessary network drives, that is, go to My Computer, right-click the mapped network drive and select Disconnect.
10, out of memory.
One advantage of Windows operating system is multi-line and multi-task. The system can use CPU for time-sharing operation, so that you can do many things at the same time. But there are advantages and disadvantages, and multitasking will also put forward higher requirements for your machine. Friends all know that even the most commonly used WORD software needs about 16MB of memory, but when running large-scale software such as 3D MAX, 64MB of memory is not enough. So at this time, the system will automatically use the hard disk space in virtual main memory to run programs and store exchange files and various temporary files. Because hard disk is a mechanical structure and memory is an electronic structure, the speed difference between them is several orders of magnitude, so virtualizing main memory with hard disk will greatly slow down the running speed of the program.
1 1, hard disk space is insufficient.
One disadvantage of using Windows system platform is unclear file management. Sometimes you don't know whether this file is useful to the system at all, so there are more and more files in the Windows directory, and the capacity is getting bigger and bigger. In addition, the current software likes more and more, and some temporary files and swap files generated by the system will make the available space of the hard disk smaller. When the available space of hard disk is less than a certain extent, it will lead to the shortage of available space of exchange files and temporary files of the system, which will reduce the operating efficiency of the system. More importantly, because we often store and delete all kinds of software on the hard disk, the available space of the hard disk becomes fragmented, so the system often does not store files in sequential order, which will lead to the frequent movement of the head when the system stores and reads files, greatly reducing the transmission speed of the system.
12, too many hard disk partitions is not right.
If your Windows 2000 is not upgraded to SP3 or SP4, and too many partitions are defined, it will take a long time to start, or even hang up. Therefore, it is recommended to upgrade the latest SP4, and at the same time, it is best not to divide the hard disk into too many areas. Because Windows must load each partition at startup, the total time to complete this operation will increase as the number of partitions increases.
Third, virus articles.
If your computer is infected with a virus, the running speed of the system will be greatly slowed down. After the virus invaded, it first occupied the stronghold of the memory, and then based on this, it began to copy itself endlessly in the memory. As it becomes more and more huge, it quickly takes up a lot of memory in the system, which leads to the slow start-up or even failure of normal programs due to insufficient main memory. At the same time, the virus program will force the CPU to execute useless junk programs, so that the system is always in a busy state, affecting the operation of normal programs and causing the computer to slow down. Here are some viruses that can slow down the system.
1, the bride virus that slows down the system.
Virus type: hacker program
Attack time: random
Communication mode: network

Alert level: ★★★★★
Virus introduction:
This virus can run normally in Windows 2000, Windows XP and other operating systems. The runtime will automatically connect to the www.hotmail.com website. If you can't connect to this website, the virus will sleep for a few minutes, then modify the registry and add itself to the registry startup item. The virus will release four virus bodies and a vulnerable virus mail and send it out through the mail system. The virus will also release FUNLOVE virus to infect LAN computers. Finally, the virus will kill dozens of known anti-virus software and make these anti-virus software invalid.
Viral characteristics
If users find these features in their computers, they are likely to be infected with this virus.
After the virus runs, it will automatically connect to the www.hotmail.com website.
The virus will release Bride.exe, Msconfig.exe and Regedit.exe into the system directory; Release: Help.eml, Explorer.exe file to desktop.
This virus will add the path of Regedit.exe virus to HKEY _ local _ machine \ software \ Microsoft \ Windows \ current version \ running in the registry.
When the virus runs, it will release a FUNLOVE virus and execute it. The FUNLOVE virus will multiply in the computer, causing the system to slow down and the network to be blocked.
The virus will look for the email address in the computer, and then send a large number of emails with the title:; (For example, if the user's computer name is Dong Zhang, the title of the virus email is Dong Zhang).
The virus will also kill dozens of famous foreign antivirus software.
If users find all or part of the above phenomena in their computers, they are likely to be infected with Bride(Worm.bride) virus. Please use their antivirus software to clean up immediately.
2. Avalon virus that slows down the system.
Virus type: worm virus
Attack time: random
Transmission mode: network/file
Infected object: network
Alert level: ★★★★★
Virus introduction:
This virus can run normally in Windows 9X, Windows NT, Windows 2000, Windows XP and other operating systems. When the virus runs, it will restore itself to TEMP, SYSTEM and RECYCLED directories, and randomly generate file names. After the virus runs, it will consume a lot of system resources, obviously slow down the system, kill some running antivirus software, and establish four threads to spread wildly in the LAN.
Viral characteristics
If users find these features in their computers, they are most likely infected with this virus:
When the virus runs, it will restore itself to TEMP, SYSTEM and RECYCLED directories with random file names.
When the virus runs, it will obviously slow down the system.
The virus will kill some running antivirus software.
The virus will modify the self-startup entry in the registry to start itself.
The virus will set four threads to spread in the local area network.
