Car owners can check the usage rate of browsers and rogue killing software in the necessary software installed online, which are the first two softwares ~!

In addition, there are many reasons for the slow boot. I will give you some articles about boot speed.

The following methods can be used for optimization (WinXP) to speed up system operation:

1, use anti-virus software to kill viruses and ensure that the system is virus-free.

2. Run the disk defragmenter to defragment and eliminate disk fragmentation.

3. Clear startup items: Start → Run →msconfig→ Start, and close unnecessary startup items.

4. Speed up the power on and off: start the registry editor, find HKEY _ current _ user \ \ control panel \ \ desktop \, change the numerical data of string value [hungatimeout] to [200], and change the numerical data of string value [WaitToKillAppTimeout] to [1000]. In addition, in HKEY _ local _ achine \ \ System \ \ Current Control Set \ \ Control, the numerical data of string value [HungAppTimeout] is changed to [200], and the numerical data of string value [waittokilservicetimeout] is changed to [1000].

5. Automatically close the stop response program: start the registry editor, find HKEY _ Current _ User \ \ Control Panel \ \ Desktop, change the numerical data of the string value [AutoEndTasks] to [1], and then restart. Automatic shutdown stop response program when shutdown: find HKEY _ user. Default \ \ control panel \ \ desktop (or HKEY _ current _ user \ \ control panel \ \ desktop), change the numerical data of [AutoEndTasks] to [1] in the right window, and log off or restart.

6. Clear the unused DLL files in the memory: start the registry editor, find HKEY _ local _ machine \ \ software \ \ Microsoft \ \ Windows \ \ current version \ \ resource manager, create a new DWORD value [AlwaysUnloadDLL] and set its value to [1]. Note: If this value is set to [0], this function will be disabled.

7. Speed up broadband access:

(1) Home Edition: Start the Registry Editor, find HKEY _ Local _ Machine \ \ Software \ \ Policy \ \ Microsoft \ \ Windows, create a new project named [Psched], and create a new Dword value [nonbestforlimit] in the right window of [Psched] and set it to.

(2) Business Edition: [Start] → [Run] → type [gpedit.msc], open the local computer policy, select [Computer Configuration] → [Management Template] → [Network ]→[QoS Packet Scheduler] in the left window, double-click "Restrict reserved bandwidth" in the right window, and select "Enable" to limit bandwidth.

8. Quickly browse * * * and enjoy the local area network: start the registry editor and find the HKEY _ local _ machine \ \ software \ \ Microsoft \ \ Windows \ \ current version \ \ resource manager \ \ remote computer \ \ namespace. There is a project under this project {D6277990-4C6A-1KLOC-0/CF-8D87-00A0060F5 BF}. Delete it, restart the computer, Windows XP will no longer check the scheduled tasks, and the speed will be significantly improved.

9. Use the L2 cache of CPU to improve the overall performance: Start the Registry Editor and find HKEY _ Local _ Machine \ \ System \ \ Current Control Set \ \ Control \ \ Session Manager \ \ Memory Management in the right window. Change the numerical data of Dword value [SecondLevelDataCache] to the same decimal value as CPU L2 cache: for example, P4 1.6G is 5 12Kb for an L2 cache, and change the numerical data to decimal value [5 12].

10. Run the defragmenter when you start the computer.

Start the registry editor, find HKEY _ local _ machine \ \ software \ \ Microsoft \ \ dfrg \ \ bootoptimizefunction, and set the string value [Enable] to: [Y] equals on, [N] equals off.

1 1, memory performance optimization

There are several options to optimize memory performance in Windows XP, which are located under the registry: HKEY _ Local _ Machine \ \ System \ Current Control Set \ \ Control \ \ Session Manager \ \ Memory Management.

(1) Disable the memory paging executor.

In general, XP will write the fragments in the memory to the hard disk, which can prevent it from doing so and keep the data in the memory, thus improving the system performance. Users with more than 256M memory can use this setting. The name of this setting is [Disable Paging Management]. Changing its value from [0] to [1] can disable memory page scheduling.

⑵ Improve the system cache: change the key value of [large system cache] from [0] to [1], and Windows XP will allocate all system memory except 4M to the file system cache, which means that the XP kernel can run in the memory, which greatly improves the system speed. The remaining 4M memory is used for disk cache, and XP will allocate more if necessary under certain conditions. Generally speaking, this optimization will improve the system performance, but it may also reduce the performance of some applications. There is more than 256M of memory to activate the large system cache.

12. Prioritize IRQ interrupt requests: IRQ interrupt numbers are set for the main components of the computer. Optimization can be achieved by modifying the priority of IRQ requests. The main optimization object is the system /CMOS real-time clock, and the performance is improved through the motherboard. First, determine which component needs higher performance and find the hardware IRQ interrupt number. Open the system properties, select the Hardware tab, click the Device Manager button, right-click the component whose IRQ number you want to check, select Properties and click the Resources tab. You can see the IRQ interrupt number used by the device. Write down the interrupt number, run the registry editor, expand HKEY _ local _ machine \ \ system \ \ current control set \ \ control \ priority control, establish a DWORD value called [IRQ # priority] ("#" is the specific IRQ interrupt number), and set its value to [1]. If the IRQ interrupt number of the system CMOS real-time clock is 8, the name of the value to be established is [IRQ8Priority]. After restarting, you will find that the performance of the newly optimized components has improved. This method is strongly recommended to optimize the CMOS real-time clock of the system. You can also increase the priority of multiple IRQ interrupt numbers, but the effect is not very good, which may cause system instability. To undo this optimization setting, just delete the registry key value you just created.

13. Close the debugger Dr. Watson: Open the directory table, find HKEY _ local _ machine \ \ software \ \ Microsoft \ \ Windows NT \ \ current version \ \ AEDebug, change the numerical data of the string value [Auto] to [0], press F5 to refresh the setting to take effect, and then cancel its operation.

14, turn off the special effects in the system properties, which is a good way to speed up. Start → Control Panel → System → Advanced → Performance → Settings → In the visual effect, adjust the settings to the best performance → OK. In this way, the desktop will be very similar to win2000. If you like the blue windows of XP, you can check "Use visual styles on windows and buttons".

15, using Windows commadner+Winrar to manage files, Win XP's ZIP support is even worse than chicken ribs, because no matter whether it is necessary or not, the boot system will open a zip support, which reduces the already scarce system resources by one point. Start → run, type "regsvr32/u zipfldr.dll" and press enter to confirm. The sign of success is that a prompt window appears: DLL is in zipfldr.dll.

16. Turn on DMA: select the IDE ATA/ATAPI controller in the device manager, enter the advanced settings of the main/auxiliary IDE channel, and set all the transmission modes to use DMA (if any), and the system will automatically turn on DMA support (also set it to support DMA in the BIOS first).

Ways to save hard disk space:

1. Delete the system backup file: Start → Run → sfc.exe/Purge Cache.

2. Delete the driver.cab driver backup file in the %windows%\\driver cache\\i386 directory.

3. If you are not used to reading Help, you can delete all the contents in the %windows%\\help directory.

4. After patching (or upgrading), you will find that %windows%\\ has many files similar to $ ntuninstallq311889 $,and delete them all.

5. Put the virtual memory file pagefile.sys on a disk other than the system disk: control panel → system → performance → advanced → virtual memory → change. Please note that the Settings will take effect.

6. Uninstall uncommon components: use Notepad to modify %windows%\\inf\\sysoc.inf, use the find/replace function, enter, hide in the find box, and replace all with ",". In this way, all the "hiding" is removed. After saving the disk, run "Add-Remove Program", and you will see many more options in "Add/Remove Windows Components". Delete games, code watches and other unused things.

7. Delete methods not used by \\windows\\ime. Reinstall your own input method.

9. Turn off system restore, which will take up a lot of hard disk space. Right-click my computer on the desktop, select Properties, find System Restore, and then select Turn off System Restore on all drives.

10, turn off hibernation: this function takes up four or five hundred megabytes of hard disk space. Closing method: Right-click the blank of the desktop and press Properties to open the display properties window → Select the screen saver page → Press the power (O) key in the lower right corner to open the power options properties window → Select the hibernation page → Remove the check before enabling hibernation (H) and confirm all the way.

1 1. Move the temporary folder of the system and users out of the system disk: right-click my computer on the desktop, select Properties, select the Advanced tab in the pop-up system properties dialog box, and then click the environment variable button to pop up the environment variable dialog box, and select under XXX user variables. In the pop-up Edit User Variables dialog box, change the variable value from the default "C:/documents and setting/user name/Temp" to "X:/YYY/temp" (X stands for the drive letter of the disk to be moved, and YYY stands for the parent folder of "temp"), then click OK to return to the Environment Variables dialog box, and then select "Environment Variables". Similarly, change the values of variables "Temp" and "Tmp" under "system variables" to "X:/YYY/Temp", and then make sure to return to the desktop and restart the machine all the way before the changes take effect. It is recommended to delete files in this folder regularly.

12. Move the temporary Internet files folder out of the system disk: Control Panel →Internet Options → General → Temporary Internet Files → Settings → Move the folder. It is recommended to delete files in this folder regularly.
