For beginners, you must pay attention to one thing: when you download something, some websites default to disk C. When you can choose to download one disk, you'd better put it on another disk. You can't choose, and there's nothing you can do. The files on disk C are also places that viruses like to patronize (needless to say, so many experts in the forum are naive, sorry).
For long-term users, drive C will accumulate some redundant information and take up too much space. Should we delete it if it is not necessary?
Deleting idle files and freeing up space can make our computer faster without wasting resources. What about deleting those?
1. Open my computer-Tools-Folder Options-View-Check the "Show all files and folders" option-OK.
2. Delete the contents of the following folder:
All files under x: \ documents and settings \ user name \ cookies \ (keep index files)
All files under x: \ documents and settings \ user name \ local settings \ temp \ (user temporary files)
X: All files (page files) under \ Documents and Settings \ User Name \ Local Settings Temporary internet Files.
All files under x: \ documents and settings \ user name \ local settings \ history \ (history)
X: all files under \ documents and settings \ user name \ recent \ (shortcuts to recently browsed files)
X: all files under \ Windows \ temp \ (temporary files)
X:\WINDOWS\ServicePackFiles (backup files after upgrading sp 1 or sp2)
Compressed file under x:\WINDOWS\Driver Cache\i386 (backup file of driver)
All files under x: \ Windows \ Software Distribution \ Download.
3. If the system has been upgraded by windoes updade, please delete the following files:
Hidden files starting with $u ... in x:\windows\
4. Then defragment the disk, and please quit all running programs during defragmentation.
5. After defragmentation, open Start-Programs-Accessories-System Tools-System Restore-Create a restore point (it is best to use the current date as the name of the restore point).
6. Open my computer-right-click the system disk-Properties-Disk Cleanup-Other options-click Cleanup in the System Restore bar-select Yes-OK.
7. After all kinds of software and hardware are installed properly, XP rarely needs to update files. Delete the system backup file: Start → Run → sfc.exe/Purge Cache nearly 3xxM. (This command is used to immediately clear the Windows File Protection file cache and release the space it occupies. )
8. Delete the dll file under \windows\system32\dllcache (minus 200——300mb). This is a backup dll file. As long as you copy the installation file, you can do it completely.
9.XP will automatically back up the hardware driver, but it is generally unlikely to change the hardware after the hardware driver is installed correctly, so you can also consider deleting this backup. The file is located in the \windows\driver cache\i386 directory and named driver.cab You can delete it directly, usually the file is 74M.
1 0. Delete unused input methods: For many netizens, not all input methods that come with Windows XPt system are suitable for their own use, such as IMJP8_ 1 Japanese input method and IMKR6_ 1 Korean input method. If they are not used, we can delete them. Input method is located in \windows\ime\ folder, occupying 88M space.
1 1. After upgrading, I found that windows\ has many directories similar to $ ntuninstallq311889 $. Kill them all, 1x-3xM.
12. Besides, putting things in the \windows\help directory is also a kind of harm to me, hehe. . . Kill them all!
1 3. Turn off system restore: The system restore function takes up a lot of hard disk space for a long time. Therefore, manual setting is needed to reduce the hard disk occupation. Open the System Properties dialog box, select the System Restore option, and select the Turn off System Restore on all drives check box to turn off System Restore. You can also set to restore only the disk or partition where the system is located. Select the partition where the system is located, click the "Configure" button, and cancel the "Turn off system restore of this drive" option in the pop-up dialog box to set the disk space for system restore.
14, the hibernation function will take up a lot of hard disk space. If you use less, you might as well turn off * * *. To turn it off, open the Control Panel, double-click Power Options, select the Hibernation tab in the pop-up Power Options Properties dialog box, and uncheck the Enable Hibernation checkbox.
15, uninstall unused components: XP installs some system components for the operating system by default, and a large part of these components are impossible for you to use. You can uninstall them in Add/Remove Windows Components. However, some components in XP are hidden by default and cannot be found in Add/Remove Windows Components. At this time, you can open the file \windows\inf\sysoc.inf with Notepad, and replace all the "hidden" characters in the file with spaces with the find/replace function. In this way, the hidden properties of all components are removed. After saving, run the Add-Remove program, and you will see many options that you didn't see before. Delete those components you don't need (remember to save them as sysoc.inf instead of the default sysoc.txt), such as Internat messenger service, fax service, Windows messenger, code table, etc. , can release nearly 50MB of space.
16. Clear the temporary files of the system: the temporary files of the system are generally stored in two locations: a temp folder under the Windows installation directory; The other is the x:\Documents and Settings "user name" \Local Settings\Temp folder (Y: the partition where the system is located). Files in both locations can be deleted directly.
17. Erase temporary Internet files: A large number of temporary Internet files generated when surfing the Internet regularly will save a lot of hard disk space after being deleted. Open IE browser, select Internet Options from the Tools menu, select the General tab in the pop-up dialog box, click the Delete File button in the Temporary Internet Files column, select the Delete All Offline Content check box in the pop-up Delete File dialog box, and click the OK button.
18. Clear the pre-read files: Although the pre-read setting of Windows XP can improve the system speed, after a period of use, the number of files in the pre-read folder will become quite large, resulting in a long system search time. Moreover, some applications will produce dead-chain files, which will increase the search burden of the system. So these pre-read files should be deleted regularly. The expected files are stored in the Prefetch folder of the Windows XP system folder, and all files under this folder can be deleted.
19. Compress NTFS drives, files or folders: If your hard disk uses NTFS file system and space is really tight, you can also consider enabling NTFS compression. Right-click the drive you want to compress-Properties-General-Compress Disk to Save Disk Space, then click OK, and select the required option in Confirm Property Change. This can save about 20% hard disk space. When compressing drive C, it is best to use safe mode for compression, which is more effective.
20. Close Dr.Watson: To close Dr.Watson, open the registry editor, find the branch of "HKEY _ Local _ Machine \ Software \ Microsoft \ Windows NT \ Current Version \ AEDEBUG", double-click the name of the Auto key under it, change its "Numerical Data" to 0, and finally press F5 to refresh the setting to take effect, thus canceling its operation. Still 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 the hard disk will be read for a long time and occupy a lot of space once the program goes wrong. If this has happened before, please look for the user.dmp file, which can save tens of MB of space after deletion.
2 1, close the remote desktop: "My Computer"-> "properties"->; "Remote" and "Allow users to connect to this computer remotely" in "Remote Desktop" are ticked.
22. Cancel XP's support for zip: Windows XP turns on support for ZIP files by default, which takes up some system resources. You can choose "Start → Run", type "regsvr32/u ZIPfldr.dll" in the "Run" dialog box, and press enter to confirm that XP can cancel the support for zip decompression, thus saving system resources.
23. Turn off the error report: When the application fails, a window will pop up to send the error report. In fact, such an error report is almost meaningless to ordinary users, so it is a wise choice to close it. In the System Properties dialog box, select the Advanced tab, click the Error Reporting button, select the Disable Error Reporting option in the Error Reporting dialog box that pops up, and finally click OK. In addition, we can turn off error reporting from the group policy: type gpedit.msc from Run, run the Group Policy Editor, expand Computer Configuration → Management Template → System → Error Reporting Function, double-click Error Reporting in the setting bar on the right, and select the Disable radio box in the pop-up Properties dialog box to disable Error Reporting.
24. Turn off unused devices: Windows XP always tries to install drivers for all devices of the computer and manage them as much as possible, which will not only slow down the system startup, but also cause a lot of system resources to be occupied. In view of this situation, in the device manager, you can disable uncommon devices, such as PCMCIA cards, modems, infrared devices, printer ports (LPT 1) or serial ports (COM 1). Double-click the device you want to disable and select Do not use this device (disable) in the General tab of its properties dialog box. Settings will take effect when you restart, and then enable these devices from Device Manager when you need to use them.
25. Regularly clean the system restore point: turn on disk cleaning and select other options-> Clean up the system restore point, and then click Clean.
26, uninstall unnecessary programs, I don't need to say this.
27, other optimization:
A. Install the application software on other hard disks (don't install it under the system disk, which is also good for reinstalling the system);
B. Transfer all My Documents folders to other partitions: right-click the My Documents icon on the desktop and select Properties-> "moving";
Transfer all IE temporary folders to other partitions: open IE browser and select "Tools"->; "internet options"->; "general"->; "settings"->; "Move folder";
Transfer the virtual memory to another hard disk;
E Point all pagefile.sys files to one place: Control Panel → System → Performance → Advanced → Virtual Memory → Change. Note that "Settings" will take effect;
Right-click the "My Computer" icon on the desktop and select "Properties"-> "advanced-performance settings"->; Advanced-Virtual Memory, set to 330-720. And clean it regularly.

Almost all users who use computers have this experience. At first, it was fine. After a while, some were stuck, some were slow, or the so-called old ones were not as good as new ones. ...
Similarly, users who use computers have almost the same experience. The newly installed system is new, but how to use it is a bit awkward. It's carefree to do it yourself or to be patched by others. This can also be called the so-called new is not as good as the old. ...
Computer operation is realized by cpu calling the storage data of hard disk, and because the reading and writing speeds of cpu and hard disk are different, in order to improve efficiency, it is necessary to set up transitional storage devices.
In the computer, the storage devices include: L 1 cache (first-level cache), L2 cache (second-level cache) inside the CPU, memory (that is, what we often say) and external storage (that is, what we often say). When running program instructions, the CPU in the computer will first look for data from the L 1 cache L2, and if it can't find it, it will go to the memory.
Because CPU is much faster than memory, CPU has to wait for memory. So no matter how fast our CPU is, its performance can't be reflected. So now the CPU integrates the cache, which is slower than the first one. Then why don't we all use cache that can read and write at high speed? This is mainly because of the price. Memory is dynamic random access memory (DRAM) and cache is static random access memory (SRAM). These two modes are different. DRAM has high integration and low price. SRAM has low integration and high price. So the general cache is 32 KB ~ 2 MB. The storage capacity of memory is much higher, and multiple memory sticks can be inserted to expand the capacity.
Memory setting is to make CPU work more smoothly. Read the program that needs to be executed into memory so that the CPU can read and write when working.
Memory plays a great role in the computer. All running programs in the computer need to be executed through memory. If the programs executed are large or many, the memory will be exhausted. In order to solve this problem, virtual memory technology is used in Windows, that is, a part of hard disk space is used as memory. When the memory runs out, the computer will automatically call the hard disk as memory to alleviate the shortage of memory, which is what we often call virtual memory.
As we all know, although hard disk can't catch up with memory in running speed, its capacity is incomparable with memory. When running a program requires a lot of data and takes up a lot of memory, the memory will be filled with data, and the temporarily unused data will be placed on the hard disk, and the space occupied by these data is virtual memory. We often see a pagefile.sys file whose capacity changes at any time under Windows XP, which is actually virtual memory.
From the above analysis, it can be seen that after the relevant conditions are determined, the free size of the memory is the decisive factor to determine the running speed of the computer. The memory is limited by its own physical size, that is, how to make the related files as little as possible or not occupy valuable memory space when using the computer.
Some people will ask, almost all the memory capacity is above G now, is this necessary? Of course, in addition to the above, using as little memory as possible without affecting the use of the computer also means reducing hardware loss and saving electricity. Why not, o(∩_∩)o ...
Similarly, some people may ask, small memory (space) will definitely affect the speed, but it is not only memory that affects the speed, but also the speed of cpu and hard disk, and the motherboard. How do you calculate these? Of course this makes sense, but you have the computer. What can you operate? Well, it is impossible to change the hardware.
What factors can determine the free size of memory? 1, physical hardware, 2, device drivers, 3, software programs, 4 virus trojans, 5, system settings, 6, startup projects, 7 service settings, etc.
The computer is in hand, its physical hardware is fixed, and the device driver is basically certain as a match with the physical hardware. As long as you use mature and official related software programs, develop a good habit of surfing the Internet, and install maintenance software, you can reduce or even eliminate the impact of software and hardware conflicts, lack of software, and poisoning the computer. This paper focuses on how to release the free size of memory as much as possible from three aspects: system setting, startup project and service setting.
Because the computer xp system used by users is absolutely huge, this paper takes xp system as an example
I. System settings
1) Remove the gorgeous appearance.
The beautiful background that we have been putting on the desktop not only wastes computer resources, but also slows down the computer's execution of applications. I want to beautify the desktop, but it slows down the computer, so we need to stop using the background. Right-click the desktop, click Properties, and then select None in the Desktop dialog box.
2) Maintain the system frequently.
If too many games, too many applications and too many old materials are installed or deleted in the system, your computer will become slower and slower. So it's best to do a comprehensive maintenance of the computer every once in a while (usually 1-3 months). Click "Start"-> "Programs"-> "Accessories"-> "System Tools" and use the "Disk Cleaning" and "Defragmentation" in it to do a comprehensive maintenance of the computer. PS: It can also be used by similar software operated by third parties.
3) Regularly clean up the traces of use.
When the computer is in use, it will produce temporary files, cache files and so on. At a certain time, it will not only occupy space, but also produce fragments, which will not only increase memory space, but also increase disk reading and writing time and affect system performance. Can be combined with the above cleaning and maintenance. For example, the historical trace cleaning tools of Jinshan cleaning experts.
4) Organize and optimize the registry.
After Windows starts, the system will read the relevant information in the registry and temporarily store it in RAM. However, when the computer is used for a period of time, it will inevitably produce a lot of garbage and remain in the registry. Therefore, it is very necessary to sort out and optimize the registry. Regarding the optimization of the registry, you can use software such as Windows Optimizer and Super Rabbit. Take the Windows optimizer as an example. Click "Clean up registration information" → "Scan", and the software will automatically clean up the garbage in the registry for you. After scanning, a menu will pop up for you to choose whether to back up the registry. It is recommended to select backup, and click "Clear" after backup.
5) Turn off the special effects in the system properties,
Right-click my computer, select Properties → Advanced, click Settings in the performance item, and then select Adjust for Best Performance. Then check "Use visual styles on windows and buttons" and "Use shadows for icon labels on the desktop".
6) compress the folder
Windows XP has a built-in. ZIP file, we can browse the zip file as a folder. But the system needs to use some resources to realize this function, so disabling this function can improve the system performance. The implementation method is very simple, just cancel the registration of zipfldr.dll, click Start-Run, enter: regsvr32/u zipfldr.dll, and then press enter.
7) Turn on the DMA transfer mode of the hard disk.
Right-click "My Computer → Properties → Hardware → Device Manager →IDE ATA/ATAPI Controller → Find the IDE channel where the hard disk is located → Properties → Advanced Settings" on the desktop, turn on the DMA transfer mode of the hard disk to speed up data reading and writing, and just check the DMA option.
8) surfing the internet
When surfing the Internet with a browser, try not to use too many plug-ins except some necessary ones.
9) The temperature of the computer environment.
When the ambient temperature is too high, the temperature of the CPU itself will rise even if the interior of the chassis is well ventilated. 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.
About system settings, I think of eight. If anyone has a better optimization performance setting, please add O (∩ _ ∩) O. ...
Second, start the project.
When installing software, many users may set the related software to boot for some reasons, but the started software is basically not used, which not only occupies memory space, but also may affect the operation of other programs. Therefore, in the "Start" option, in addition to killing software and input method, try to be empty.
1) 1
Enter msconfig in the Start-Run dialog box, open the system configuration utility, and select Start.
2) "Start" project
Windows Start has its own startup folder, which is the most common startup item. The specific location is "All Programs"-"Start" option in the start menu.
The location on the hard disk is: c: \ documents and settings \ your user name \ start menu \ programs \ start.
The location in the registry is:
HKEY _ Current User \ Software \ Microsoft \ Windows \ Current Version \ Running.
3) The corresponding startup add-in in the registry.
Run subkey -in
[HKEY _ Current _ User \ Software \ Microsoft \ Windows \ Current Version \ Running] and
Under [HKEY local machine \ software \ Microsoft \ Windows \ current version \ running].
Third, the service settings
A service is an application type that runs in the background, similar to a UNIX background application. Service applications can usually provide some functions to users locally and through the network, such as client/server applications, Web servers, database servers and other server-based applications.
Services can be divided into services required by the system and services not required. Necessary services are indispensable for system operation. If necessary services are prohibited or damaged, the system may be abnormal or crash or affect Internet access. Non-essential services are services that can be prohibited.
PS: Although the prohibited services listed in this article will not affect the use of the system, users must know what they are doing when operating, so that when they want to recover, they can reverse the operation to recover it O (∩ _ ∩) O. ...
