Windows XP application optimization Guide

Author: lonely dream Source: China start Network Security Group

I bought my own computer since the start point was closed. As a result, I became financially nervous, so I stopped the bubble network and did not learn hacker knowledge. During this time, I kept installing the system, dizzy. So I have a little understanding of XP and 2000 systems. Today, the Black Wolf suddenly asked me to write an original article to him. Even if the technology is not enough, I will not be able to study online for N days, so basically nothing will happen, Khan ~~ I will write some articles on XP system optimization and 2000 system defense. I have also referred to a lot of materials, and the text expression is not very satisfactory, but the level is really low, I hope new users who are new to computers can understand it.
1. Cancel XP's default support for ZIP Stability
XP supports ZIP Encryption by default, but the system consumes a lot of resources. We can disable this function, select "run" at "start", and enter regsvr32/u zipfldr. dll is OK.
2. Set the permission for shared folders in XP
Win2000 operating system users can easily set folder sharing, but cannot find this function in XP. The specific modification method is as follows: Open "Tools" in "My Computer ". Select "folder properties" to bring up the "View" tag. In the file and folder sections, deselect the option "use simple file sharing (recommended, in this way, you can easily set the sharing.
3. quickly lock the computer
Select the latest available option. When the system starts to create a wizard, enter rundll32.exe user32.dll and LockWorkStation In the example box. The next step is to set the function properly.
4. The "Sleep" dialog box appears"
When the shutdown dialog box appears, you can press the shift key at the same time to sleep.
5. Solve the task bar crash (authoritative elimination of QQ, IE, and other causes of Task Bar crash)
"Control Panel" "region and language options" "language" "details", select the "preference" language bar in the pop-up settings window, and close "show language bar on the desktop ", in the third item "show other language bar icons in the comrade Area", it is OK.
6. How to use a 16-bit program in winXP
Enter start/separate d: TC2c.exe in the command interpreter, and press alt + enter to switch the screen.
7. Find the installation password in XP
Open the system drive letter "windows system32. Here is a configuration file named $ winnt $, which is clear.
8. Reduce disk scan wait time
Enter chknfs/t: 0 in dos, indicating that the wait time is 0 seconds.
9. Implementation of Automatic shutdown in winXP
For example, if you want to shut down your computer at, you can select "start", "run", and enter "shutdown-s" so that the automatic shutdown dialog box will pop up at the specified time, the default wait time is 30 seconds. If you shut down your instance in the instant recording mode. You can enter shutdown.exe-s-t 3600, indicating that the system will automatically shut down 60 minutes later. The value 3600 indicates 60 minutes. If you want to cancel the operation, enter shutdown-a in the running process, and enter shutdown-I to set the automatic shutdown dialog box. The Shutdown parameter settings are as follows:
-F: forcibly close the application
-M \ computer name: controls remote computers
-I: displays the graphic user interface.
-R: Shut down and restart
-T time: Set the shutdown countdown
-C message content: Enter the message content in the shutdown dialog box.
10. run multiple commands in sequence
You can also use the & | combination of XP command lines, such as aa & bb to execute aa, and then execute bb; aa | bb to execute aa first, if the operation is successful, no bb is executed. If the operation fails, no bb is executed. The returned value errorlevel = 0 indicates that the command is successfully executed.
11. Accelerate start-up and reduce fault recovery time
Right-click "my computer", "properties", and "advanced", and click "set" in "Start and fault recovery" to set the time for displaying the operating system list, you can also click Edit to manually edit the startup option and change timeout = 30 to 5.
12. Reduce disk space waste
During Running of the winXP operating system, files with names such as tmp, bak, log, txt, and old will be generated. These files can be deleted safely, bmp files in windows can also be deleted, if you do not like the wallpaper that comes with XP. Files in the Windows/temp directory can also be completely deleted, which are all files left by you during application installation.
13. Visual Effects
WinXP is indeed more elegant than win9X in terms of menu effects, but for users with small memory, we can modify it if it occupies too much memory, right-click "my computer" "property" "advanced", click "set" on the performance options, and click "adjust to optimal performance" to remove all animation effects, this speed must be significantly improved. You can also enter regedit in "start" "Run" to go to the Registry Editor, find the item with the key value MenuShowDelay in the right window of HKEY_CURRENT_USERcontrol PanelDesktop, and change the default value to 0.
14. Set hard drive mode
The hard disks we use are generally relatively large. We can use DMA instead of PIO to increase the transmission speed of the hard disk, reduce your cpu usage, and improve your system performance. The settings are as follows: "Start" "control" Panel "" performance and maintenance "" view basic computer information "" Device Manager "" ide ata/ATAPI controller "" IDE channel "" attribute "Advanced Settings ", select "DMA" in transfer mode.
15. outlook express
This technique reduces the OE error rate. On the OE page, open "tool" and "Account" in the menu, select your account, and then select "attribute" and "advanced ", it takes up to five minutes for the server to time out.
16. Modify the disk cache acceleration system
Run regedit to enter the registry and find HKEY_LOCAL_MACHINESYSTEMCurrentcontrolsetcontrolsession managermemory managementlopagelocklimit. Modify the hexadecimal value based on your memory.
64 M: 1000:
128 M: 4000;
256 M; 10000;
40000 m or larger;
17. Pre-read settings increase speed
Run regedit to find [HKEY_LOCAL_MACHINESYSTEMCurrentcontrolsetcontrolsession anagermemory managementPrefetchParametersEnablePrefetcher] and set it to 3. And then restart.
18. Disable disk Indexes
If you do not often find files visible XP quick search function is disabled, open my computer and select "properties" on a drive to cancel "use index to quickly find files ".
19. Optimize the NTFS file system
Cancel disk access to the last update. The speed of disk access is slowed down by running regedit to locate HKEY_LOCAL_MACHINESYSTEM Currentconlsetcontrolfilesystem. Add the DWORD Value to 1.
20. Disable system services. Improve Running Speed
XP consumes a lot of resources. In addition to the beautiful interface, it consumes a lot of memory and video memory. By default, many services run in the background, which are not required for individual users, we can disable all unnecessary services.
Application layer gateway service if you do not use internet Connection Sharing or built-in firewall, you can disable this service.
The Automatic update function automatically downloads and installs windows updates. When necessary, you can update the UPDATE function on the windows Website.
Clipbook can be disabled if you do not use the xp Remote Desktop function.
Error reporting service and applications are allowed when running in non-standard environments. Generally, it is useless. We can disable it.
Fast user switching compatibility allows switching between multiple users on a computer in xp. If not, you can disable it.
Imapi cd-burning com service can be disabled if you have professional recording software or no recorder.
The Indexing service provides fast file access, which is not very useful to individual users and can be disabled.
Print spooler: if you have not installed a printer, you can disable this service.
Remote registry Remote users can modify their registration reports, which must be disabled.
Smart card manages computer access to Smart cards. Smart Cards? Do you have one? Forbidden!
Ssdp discovery service generally does not use the discovery of upnp devices on the home network. Forbidden.
Terminal services is not afraid of N people controlling your computer, so do not prohibit it. Haha, login 3389, prohibit!
Uninterruptible power supply if you have a ups power supply that can communicate with your computer, do not disable it. Otherwise, do not disable it.
21. completely hide the file
Generally, everything hidden by using the folder option appears when a hidden file is opened. We set the value of DWORD CheckedValue in HKEY_LOCAL_MACHINESOFTWAREMicrosoftwindowscurrent versionpoliceradvancedfolderhiddenshowall to 0 (if no new one can be created ). This is OK!

Windows 2000 system reinforcement

The personal users who use the XP system generally aim for their beautiful interfaces, but those technical pursuers will not be tempted by the beautiful interfaces of XP, so I will mainly introduce the optimized application of the XP system and the security reinforcement of the 2000 system,
2000 system security has always been a headache for network administrators. Although win2003 has been launched, many still use the 2000 system, in fact, as long as you set the system correctly and add security software, the security can be greatly improved, but there is no absolute security setting. Every system has vulnerabilities, and attack and defense are always opposite. The following describes the settings of 2000, and no security software is used. The security reinforcement process for the 2000 system is described as follows:
1. Install a minimal operating system and the latest service package;
2. install and configure the application you want to run on the host;
3. Apply for a new service package and install the latest security patch;
4. delete or disable unnecessary services and components in the operating system;
5. Reinforce other parts of the operating system;
6. set strict access control permissions for files and other objects.
The following describes the procedure:
1. Minimal Operating System Installation Considerations: from a clean system, do not install multi-system startup on the host to prevent damage caused by startup control of other systems. Only NTFS partitions are used as file system partitions because they provide Log check information. In addition, you must use NTFS to use DACL for files to achieve access control security. Only the TCP/IP protocol is installed, and no other protocol is installed, do not install any additional programs or services when selecting an installer. If the server version of win2000 is installed, configure it to standalone (independent server) mode.
2. install and configure applications and service programs: do not install any redundant programs, install and use services and applications carefully, and select the latest installation and service version whenever possible. Install and configure the normally used applications on your system, and install and configure the programs you selected to provide network services on your system. Check whether the program you want to install has security defects. In an application environment with high security requirements, do not install MS-ofiice or any development tools. The fewer executable programs, the better.
3. apply for a new service package and install the latest security patch: Microsoft provides the windows update Program, which can be directly connected to the Microsoft download site to obtain the updated hotfix, that is, the security patch released after the release of the large service package, it is usually used to compensate for recent security vulnerabilities.
4. Configure the services provided by the operating system: Disable all unnecessary services provided by the operating system. Enable system services that have other requirements as required,
