Playing the computer will inevitably reinstall the system, which is the most easy thing for computer experts, but do you know when computer experts most headaches? Is installed after the system to do things, which can not be sloppy, because once done badly, it will lead to failure, and may even cause data loss or reinstall the system.One.PC Security and Protection1. Turn off default sharingAfter Windows is installed, some hidden shares are created, which are not very secure. We can cut off the sharing by pressing Win + R, entering gpedit.msc, expanding the User Configuration Windows Settings Scripts (Login / Logoff) folder step by step in the open window, double-clicking in the sub-window to the right of the Scripts (Login / Logout) folder, deleting the Login option, and deleting the shared batch. For example, the script file shown here is "delshare.bat" in the C disk. you can delete the Windows default share by clicking the OK button. Note that the "delshare.bat" in the C disk must be created in advance by yourself with the following code:@echo offnet share C$/delnet share d$/delnetshare ipc$/delnet share admin$ /delAfter completing the above setup, reboot the system to automatically cut off the default shared channel for Windows 2003. If you have more hard drives, add them yourself under net share d $/ del, such as net share e $del, net share f $/ del, etc.2. Don't rush to access the networkAfter installation of Windows, do not immediately connect the server to the network, because the server has not been patched at this time, there are various vulnerabilities, very easy to be infected with viruses and intrusion. This time to add the shock wave and shock wave patches and restart and then connect to the Internet.Tip: Patches should be installed after all applications have been installed, because patches often have to replace or modify certain system files. If patches are installed before applications are installed, patches may not work as expected. HotFix for IIS, for example, requires that you reinstall each time you change the configuration of IIS.3. Disable empty connectionsBy default, any user can connect to the server via an empty connection, enumerate accounts and guess passwords. There are two ways to disable an empty connection.(1) Modify the key “ofLocal _ Machine \\\\\\\\CurrentControlSet \\\\\\\\Control \\\\\\\\LSA” Restrich Anonymous to 1.(2) Modify the local security policy for Windows 2000 and set the "Local Security Policy Local Policy Options" in the Restraint Anonymous (an additional restriction on anonymous connections) to "Do not allow enumeration of SAM accounts and shares."4. Consider playing SP2The latest patch is the simplified Chinese version of Windows XP Service Pack 2, but not everyone needs this one.5. Disconnect the Auto Save channelOnce a Windows system accesses a program in error, the Dr.Watson program in the system automatically saves some of the personal privacy information at the time of the error, which is often the hacker's favorite "stalking"; to avoid leaking the privacy information, you should disable the automatic saving feature of the Dr.Watson program:Open Registry Editor, expand “HKEY_local_machine\\\\\\\\software\\\\\\\\Microsof\\\\\\\\WindowsNT\\\\\\\\CurrentVersion\\\\\\\\AeDebug” Button,To the right of the corresponding AeDebug subkey, double-click the Auto value and set the Value data to 0. Then enter the system's DrWatson folder (located) and delete the User.dmp, Drwtsn32.log.6. Prevent filename spoofingSet the following options to prevent filename spoofing, such as preventing a malicious file with a.txt or.exe suffix from being displayed as a.txt file to make the file more open: double-click My Computer Tools Folder Options View, select the Show All Files and Folders property setting, and remove the Hide Known File Type Extension property setting.Two. Driver Backup and Hardware Optimization1. Set the CPU's L2 Cache to speed up overall performanceOpen Registry Editor, expand “HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/SessionManager/MemoryManagement”， In the right window, change SecondLevelDataCache to a decimal value like CPU L2 Cache (for example, L2 Cache of P4 1.6G is 256Kb, it changes to a decimal value of 256).2. Enable DMA transfer modeWhen DMA mode is enabled, computer peripherals (mainly hard disks) can exchange data directly with memory, which can speed up the read and write speed of hard disks and increase the data transfer rate by:Select Control Panel System / Hardware to open Device Manager, where the IDE Controller has two Primary IDE Channels and Secondary IDE Channels, then go to Properties Advanced Settings. This dialog lists the transfer modes of the devices currently connected to the IDE interface. Click the list button to set the Transfer Mode to DMA (if available).3.Set up virtual memoryGo to "Control Panel System / Advanced / Performance / Settings. In the" Advanced "Settings window of" Performance Options ", first adjust both "Processor Plan" and "Memory Usage" to "Program" so that the system will give more resources to the foreground program and make it run faster. Click the "Change" button to enter the Virtual Memory Settings window, set the virtual memory value to 2.5 times the physical memory value, and set the initial size to the same as the maximum.If your memory is larger than 256M, it is recommended to disable the paging file; if the memory is lower than 256M, do not disable the paging file, or you will crash the system or fail to start XP again!Three. System Performance OptimizationAs long as we follow the steps below to optimize XP, adjust the system to the best condition, you can greatly improve the speed of the system operation.1. Turn off error reportingClick Start Settings Control Panel, open the Control Panel, double-click System, click the Advanced tab, click the Error Reporting button, select Disable Error Reporting, and uncheck the "Notify me of critical errors" checkbox below, then click OK to exit.2. Mitigate tasks loaded at startupMany software will automatically load at XP startup, making the system boot time longer and should cancel the automatic load of the software. Select Run from the Start menu, type msconfig to start the System Configuration Utility and enter the Startup tab, which lists the items loaded at system startup and their source. If you do not want it to load automatically, clear the check box before the item.3. Modify the registry to reduce pre-reads and reduce progress bar wait timesOpen Registry Editor, expand the registry”HKEY_LOCAL_MACHINE\\\\\\\\SYSTEM\\\\\\\\CurrentControlSet\\\\\\\\Control\\\\\\\\Session Manager\\\\\\\\Memory Management\\\\\\\\PrefetchParameters”， One key, Enable Prefetcher, changes its value to "1", and a friend who doesn't change hardware often can set the device type on the bus device to none in the system properties.4. Cancel ZIP support for Windows XPClick Start Run, enter "regsvr32 / u zipfldr.dll" Enter and a prompt window "Dll Unrgister Server Success in zipfldr.dll" appears to cancel ZIP folder support for Windows XP.5. Quickly browse local network sharingTypically, when Windows XP connects to another computer, it thoroughly checks all scheduled tasks on the other computer, a check that can wait 30 seconds or more. The way to remove it is to delete the registry “HKEY_LOCAL_MACHINE\\\\\\\\Software\\\\\\\\Microsoft\\\\\\\\Windows\\\\\\\\Current Version\\\\\\\\Explorer\\\\\\\\RemoteComputer\\\\\\\\NameSpace” Keys under key values, After you restart your computer, Windows XP no longer checks for scheduled tasks.6. Turn off redundant servicesClick Start Settings / Control Panel, double-click Administrative Tools Services, right-click the service you want to configure, click Properties, and on the General tab, select Automatic, Manual, or Disabled. In actual configuration, select either Manual or Disabled to turn off the service. Manual functions are recommended so that some services that are needed temporarily can be started at any time.7. Reduce wait times for multiple startsWhen Windows XP coexists with other Windows, a startup menu is displayed for each startup. To close the startup menu, click the Settings button under Startup and Recovery, click Control Panel System Properties Advanced, and enter the Settings window. Select Windows XP as the default operating system at startup, with a time of 0 to display the boot menu, or uncheck the checkbox before "Show operating system list time" if you are not using or hiding another operating system temporarily.8. Automatic shutdown for Windows XPIf XP does not shut down automatically, click Control Panel Power Options Advanced Power Management to check Enable Advanced Power Management. If not, it should be a problem with the motherboard BIOS.9. Optimize the XP interfaceXP installed after the taskbar, start menu, desktop background, windows, buttons, etc. are used XP luxury style, very wasteful of system resources, it is recommended to restore the Windows classic interface: right-click in the desktop space, simply click "Properties" to enter the display property settings window, "theme, appearance" are set to "Windows Classic", set the desktop background to "None", press OK to exit. Right-click the taskbar and select Properties. In the Taskbar tab, remove the check mark before Group similar taskbar buttons. In the Start Menu tab, select Classic Start Menu.10. Turn off Remote DesktopClick"My Computer-Properties / Remote", and under " Remote Desktop ", remove the " Allow users to connect to this computer remotely " check box.
11. Turn off System RestoreBy default, XP enables System Restore, which consumes approximately 4% to 12% of hard disk space per drive, and the System Restore monitoring system automatically creates restore points, which can take up more system resources when running in the background and should be turned off: Right-click "Properties" in "My Computer" and click " SystemProperties System Restore " to select "Turn off System Restore on all drives". You can also turn off System Restore for unimportant partitions. If you are concerned about system security, do not turn off the Restore feature.12. Use fewer visualsClick "Control Panel System" and select the "Advanced" tab in "System Properties" to enter the "Performance Options" screen. There are many "visual effects". The more effects selected, the more system resources used, so we selected the "Adjust for Best Performance" item in order to turn off allvisual effectssuch as fading, smooth scrolling, sliding and opening.13. Turn off the effects in System PropertiesClick "Start Control Panel System Advanced Performance Settings" and in Visual Effects, set to Adjust for Best Performance OK. This desktop will be very similar to Windows 2000, I still like XP's blue window, so in the "use visual styles on windows and buttons" check the box, so you can see the beautiful blue interface, but also to speed up.14. Speed up menu displayClick Start Run, type Regedit, and enter [HKEY_CURRENT_USER\\\\\\\\Control Panel\\\\\\\\Desktop]， MenuShowDelay change to 0 (or 200 if you feel out of place), the reboot will take effect. XP's Start Menu and even the app's Menu display will be significantly faster after the change.15. Speed up XP shutdownClick Start Run, type Regedit, and set the HKEY_CURRENT_USER\\\\\\\\Control Panel\\\\\\\\Desktop\\\\\\\\WaitToKillAppTimeout change to 1000, Wait only 1 second to close the program; change the key value of HungAppTimeout to 200, indicating a 0.5 second wait if the program fails; set the HKEY_LOCAL_MACHINE\\\\\\\\System\\\\\\\\CurrentControlSet\\\\\\\\Control\\\\\\\\WaitToKillServiceTimeout Set to 1000 or less.To have the system automatically shut down a program that stops responding by setting the HKEY_CURRENT_USER\\\\\\\\Control Panel\\\\\\\\Desktop\\\\\\\\ AutoEndTasks The value is set to 1 and takes effect when the computer is restarted.16. Turn off the disc function in XPBy default, XP turns on the built-in Cartridge feature, which speeds up Nero burning software and can be turned off if not used: click Control Panel Administrative Tools Services, double-click IMAPI CD-Burning COM Service, and change the Startup Type to Manual or Disabled.
17. Change the image view thumbnail size and image qualityWindows XP Basic has Windows 2000's Picture Browsing Thumbnail feature, which makes it easy for us to view pictures in folders. We can change the size of thumbnails by modifying related entries in the registry to display more thumbnails on one page. This can be done by typing Regedit in Start Run, opening the Registry Editor, and expanding the branch [HKEY_LOCAL_MACHINE\\\\\\\\Software\\\\\\\\Microsoft\\\\\\\\Windows\\\\\\\\CurrentVersion\\\\\\\\Explorer], In the right-hand window, create a new DWORD value called Thumbnail Size, which can range from 32 to 256 (decimal). It is recommended that you select 50 (the default is 100), which reduces the thumbnail size so that more thumbnails can be displayed on the same page. We can see the results as soon as we exit the Registry Editor, which greatly facilitates our search when the preview effect is not required.Viewing a file as a thumbnail inevitably consumes disk space and memory, and we can relieve disk and memory pressure by changing the image quality of the thumbnail. Also add a DWORD value called Thumbnail Quality in the right-hand window of the registry branch, which is set to between 50 and 100 (decimal) and is recommended to be set to 50. Also, if you click "View Thumbnail" in "My Computer" and hold down the Shift key at the same time, the file name will not be displayed under the thumbnail that appears. To display the file name again, simply select another viewing method and then select "Thumbnail" mode.18. Consider completely disabling the thumbnail feature of Windows XPMemory is not rich for users, thumbnail function is a bit worse, you can disable the thumbnail function! Open the "Registry Editor", expand branches [HKEY_CURRENT_USER\\\\\\\\Software\\\\\\\\Microsoft\\\\\\\\Windows\\\\\\\\CurrentVersion\\\\\\\\Explorer\\\\\\\\Advanced], Find the "Classic ViewState" item in the right window and change its value to 1. Then open the Explorer, click Tools Folder Options, go to the View tab, and select the "Do not cache thumbnail" item in the Advanced Settings bar.
