The ultimate tip of Windows XP acceleration Setup _windowsxp

Hardware Optimization

　　 1, Memory performance optimization

There are several options in Windows XP that can optimize memory performance, all of which are located under the registry: Hkey_local_machinesystemcurrentcontrolsetcontrolsession Managermemory Management

1) Disable memory page scheduling (paging Executive)

Under normal circumstances, XP will write fragments in memory to the hard disk, we can prevent it to do so, so that the data remain in memory, thereby improving system performance. Note that users with a lot of memory (more than 256M) are better off using this setting. The name of this setting is the same as its function, called "disablepagingexecutive". Changing its value from 0 to 1 prevents the memory page from being scheduled.

2 Upgrade the system cache: the LargeSystemCache key value from 0 to 1,windows XP will be in addition to 4M of system memory allocated to the file system cache, which means that the XP kernel can run in memory, greatly improve the system speed. The remaining 4 m memory is used for disk caching, and XP will be allocated more when needed under certain conditions. In general, this optimization can lead to a considerable improvement in system performance, but it is also possible that some application performance will be reduced. As mentioned above, there must be more than 256M of memory to activate the LargeSystemCache, otherwise do not move it.

3 Input/Output performance: This optimization only for the server users have a real meaning?? It can improve the performance of the system for bulk file transfer. By default, this key value does not exist in the registry, you must build a DWORD (double-byte value) key value, named Iopagelocklimit. Most people find the best performance between 8 and 16M bytes when using this optimization, specify what value, you can set into the words to allow the key to 鲋 mourning song Rice was walking my research and read the Pro ≌ chiselled stool cowardly paper alcohol flutter 鲋 model Yie to play  ┤ lowered zhi? 2M, 12 * 1024 * 1024, which is 12582912. As with the previous memory optimizations, you can change the value only when your memory is larger than 256M.

　　 2. Turn on DMA: To the appliance Administrator Select IDE ATA/ATAPI controllers, to the Primary/secondary IDE channel in the Advanced settings, all the forwarding mode is set to use DMA (if available), the system will automatically turn on DMA support ( In the BIOS should also be set to support DMA first)

　　 3, XP to turn off the CD-ROM drive (Autorun) function: Open: My Computer, under Removable Storage devices, right-click the CD-ROM drive, and then click Properties, see the AutoPlay tab? Change it yourself.

　　 4. Set CPU: Windows XP cannot automatically detect the processor's level two cache capacity, requires us to manually set up in the registry, first open the registry (enter "Regedit" in Run), and open:

Hkey_local_machinesystemcurrentcontrolsetcontrolsession managermemory Management, select "Secondleveldatacache", Based on your own processor settings, such as PIII COPPERMINE/P4 Willamette is "256", Athlon XP is "384", P4 Northwood is "512"

5, XP installation driver, often appear a window, said this program has not been verified by Microsoft, we can in the control Panel?? System?? Hardware?? Device Manager?? Driver signature, you see the options, you know what to do.

　　 6, for IRQ interrupt request row Priority

Each major part of the computer has an IRQ interrupt number set. This is done by modifying the precedence of each IRQ request to achieve the optimization goal. The main optimization object here is the system/cmos real-time clock, which improves performance through the motherboard. First, determine which component you want to achieve higher performance, and then find the IRQ interrupt number that the hardware is using. How do I find it? Open the System Properties in the Control Panel (or press the Windows+break hotkey combination on the keyboard to open it). Select the Hardware tab, and then tap the Device Manager button. Right-click the component that you want to check for IRQ numbers, select Properties, and then tap the Resources tab. Here you can see the IRQ interrupt number that the device is using (if there is no IRQ interrupt number, select another device). Write down the interrupt number, and then run Registry Editor regedit to locate the Hkey_local_machinesystemcurrentcontrolsetcontrolprioritycontrol location in the registry. We're going to create a DWORD value called Irq#priority (where "#" is a specific IRQ interrupt number), and then set its value to 1. For example, my system CMOS real time clock IRQ interrupt number is 8, I want to establish the key name is irq8priority. After you restart your computer, you will find that the components you have just optimized have improved performance. This method is strongly recommended to optimize the system CMOS real-time clock, because it can improve the performance of the whole board. Of course, you can also increase the number of IRQ interrupt priority, but the effect is not so good, and may cause system instability. To undo this optimization setting, just delete the registry key you just created.

　　 third, network optimization：

　　 1. Speed up sharing: This is a great optimization, and before I find this optimization, I often knock on my scalp in a long wait window to display a shared directory on another machine. Typically, when Windows XP connects to another computer, it checks all scheduled tasks on the other machine?? It's really superfluous, and it'll keep you waiting for 30 seconds, and that's too bad. Fortunately, it's easy to get rid of the process. First, find Hkey_local_machinesoftwaremicrosoftwindows/current Versionexplorerremotecomputernamespace in the registry. In this case, there should be a

{D6277990-4C6A-11CF-87-00AA0060F5BF} key. Just delete it, restart the computer, Windows will no longer check the scheduled task, the speed is significantly improved!

　　 2, solve the problem of WinXP execution time pause

Begin?? Network connection?? Local connection, right-click, select Properties, select Internet Protocol (TCP/IP), click Properties, use the following IP address: 192.168.0.1, subnet mask: 255.255.255.0, this is good, then the boot will not be stopped

　　 3, how to let XP automatic networking:

Ie?? Tools?? Internet Options?? Connect, tick ' dial when network does not exist ', pull IE to ' start '

After each boot completes, you already on-line! There is another way:

Enter the line content, the "prompt name, password, voucher, etc." tick off, and then pull the line to "Start" (Blues note: The original author is estimated to be RTHK, the terminology is different. Because I use broadband on the internet, so what is the language of Simplified Chinese is not clear. Modify a successful friend back to a post, easy for me to modify. ）

　　 4, by default, XP Pro will retain a 20% of the bandwidth of a network card。 The modified method is to login with admin privileges, Start menu?? Run?? Type gpedit.msc, the Group Policy window appears, expand Network in Administrative Templates, expand ' QoS Packet Scheduler ', and right-click ' Restrict reserved bandwidth ' in the property, in the settings, with ' limit to reserved bandwidth ', select ' enabled ', and then ' bandwidth throttling ' Select a value on the column. You cannot choose ' Disable ' because in that case, you will be given the option to retain 20% of the bandwidth. You can refer to the "description" section next to "Properties" for specific modifications. When the above modifications are done and applied, the user should be able to see the ' QoS Packet Scheduler (QoS Packet Scheduler) ' In the General Properties tab bar of the Properties dialog box for the network connection. The home version does not support this operation and cannot remove the limit!

　　 5, XP built-in firewall, the default setting is not open。 Set the method as detailed in the following "Comprehensive firewall setup."

　　 Four, XP system partition Weight loss method。

1. Delete system files backup Sfc.exe/purgecache (common users are not used)

2 Delete Drive backup windowsdriver cachei386 directory Driver.cab file (73MB)

3. Cancel System Restore (the overall System Restore function is good, recommended in addition to the XP installation of the disk use, other dishes are not used, if the hard disk space is not enough, you can remove some of the earlier restore points through the System Cleanup program)

4, delete the Help file (lose more than 40 MB) (the use of Chinese-language package file size of 92 trillion, just beginning to use XP comrades best not to delete)

5, delete the Windowssystem32dllcache under the file (minus 200?? 300MB). (This is an alternate DLL file, as long as you copy the installation files, you can do so.) Since you have nothing to say about this,

6, My Documents, ie temporary folder to other disk (partition). (at the same time to the system speed, and hard drive are good, if the use of dual systems, it is best to put both systems of IE temporary files in the same folder, so as to speed up the space to save)

7, the virtual memory also transferred to other disk. (is to put these things in peace temporary download files in a small partition, so that easy to defragment the hard drive)

8, the application software installed in other disk (this is also good for reloading the system, you can save a lot of things).

9, delete the windowsime of the input Method! (Japanese, Korean, Traditional Chinese input method, 84.5MB) (which is the one who is the study of it!) Sometimes you have to do your own brain, exercise it! ）

10, if the use of NTFS installed XP, itself to save territory.

　　 v. Other

1. Activation Display:

After the boot, open the Start menu of the Run bar, into: oobe/msoobe/a

If "Windows Product Enabled" appears, Windows is enabled

2, making DOS boot disk:

Right-click on "3.5 floppy disk", choose Format, and then select "Create an MS-DOS boot Disk"

3, solve the task bar suspended animation (authority of the elimination of QQ, IE, etc. caused by the task bar suspended animation)

Control Panel '-?? ' Regional and Language Options '-?? ' Language '-?? ' Details ', select the ' Language bar ' of ' preferences ' in the pop-up ' Settings window ', turn off the "show Language bar on the desktop", and tick the third item ' show other Language bar icons in the notification area ' check box. If you do not need handwriting recognition, speech recognition, you can also check the last "Turn off advanced text services."

4, some software compatibility (applicable to the home version of ' Homeedition ' and professional version of ' Professional ')

For the QQ suspended animation, and some other programs under XP can not be normal operation of the phenomenon, you can find the program's execution file, right click, in the pop-up dialog box to select the ' Compatibility ' tab, in the ' Compatibility mode ' under the corresponding need to choose the operating environment.

5, dual operating system, how to uninstall XP

Start with a Startup disk, then type "A:sys C:" and reboot from the hard drive, then delete boot.ini, Bootsect.dos, Ntdetect.com, NTLDR, and then put XP windows, program files, Directories such as Documents and settings are deleted directly, or the WinXP hard drive is formatted (if your XP and Win98 are not on a partition)

6, how to determine whether XP is the official version of Chinese.

Open to see the installation folder I386, find Setupp.ini, open with Notepad, if the content is:

If the same as the following, it is in English version of the Corpfiles patch.

[Pid]

Extradata=796674736977656d7a622e385892a4

pid=55274270

The current outflow of Chinese Enterprise version Setupp.ini content is

[Pid]

extradata=766e74737a7b787061627428828710

pid=55394270
