Realization of 1 sec shutdown in Win XP system

The huge Windows XP operating system shuts down very slowly, which takes about 30 ~ 50 seconds. However, if you change the registry options according to the methods provided below, your Windows XP system will shut down soon.

Find the key current user \ control panel \ desktop key, and change WaitToKillAppTimeout to: 1000, that is, just wait 1 second when closing the program.

In addition: how to quickly close the program that the system automatically shuts down and stops responding when an error occurs.

1. Change the HungAppTimeout value to: 200, which means that the program will wait for 0.5 seconds when an error occurs.

2. Set the AutoEndTasks value to: 1, so that the system can automatically close the program that stops responding.

First, speed up the plan

WinXP startup will have many functions that affect the speed. Although ms says it has been optimized, there are still many customization places for us. I usually do this.

1, modify the run key of the registry and cancel those things that are not commonly used, such as Windows Messenger. Enable Registry Manager: Start → Run →Regedit→ Find the key value of "HKEY _ Current _ User \ Software \ Microsoft \ Windows \ Current Version \ Run \ MSMSGS"/background, right click → Delete, the world is much quieter, and kill all those cfmon by the way.

2. Modify the registry to reduce the waiting time of pre-reading and progress bar. The effect is that the progress bar will enter the login interface after running once. Start → Run →regedit mobile registry editor, and find HKEY _ local _ machine \ system \ currentcontrolset \ control \ session manager \ memory management \ prefetch parameter. There is a key to make Prefetcher change its value to "1". In addition, friends who don't change their hardware often can set the device type above the bus device to none in the system properties.

3. Turn off the special effects in the system properties, which is a simple and effective acceleration method. Click 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. I still like the blue window of XP, so I put a check on "Use visual styles on windows and buttons" so that I can see the beautiful blue interface and speed up.

4. I use Windows commadner+Winrar to manage files. The ZIP support of Win XP is even worse for me, because no matter whether I need it or not, the boot system will open a zip support, and the already idle system resources will be less. Click Start → Run, type "REGSVR32/U zipfldr.dll" in the middle of double quotation marks, and then press enter to confirm. The sign of success is that a prompt window appears, and the content is roughly as follows: Dll UnrgisterServer in zipfldr.dll is successful.

It is said that a system of XP serves Qos, and this scheduling takes up 20% of the network bandwidth, which people like us can't afford. The way to get rid of it is: start menu → run → type gpedit.msc, and the group policy window will appear, expand management template → network, expand QoS packet scheduler, and right-click in the right window to restrict reservation. After completing and applying the above modifications, if users can see "QoS Packet Scheduler" in the general properties tab of the properties dialog box of network connection. It means that the modification is successful, otherwise it means that the modification has failed. By the way, kill (uninstall) the Qos protocol in the network properties.

6. Enjoy a quick browse of the LAN.

Usually, when connecting to other computers, Windows XP will comprehensively check all scheduled tasks on other computers. This check will make you wait for 30 seconds or more. The way to get rid of it is to start → run →Regedit→ find HKEY _ local _ machine \ software \ Microsoft \ Windows \ current version \ resource manager \ remote computer \ namespace in the registry. Under this key value, there will be a key {d6277990-4c6a-11cf-8d87-00aa0060f5bf}. After deletion, restart the computer, and Windows XP will no longer check the scheduled tasks. Hoho ~ ~, the speed is obviously improved!

7. Close the debugger, Dr. Watson.

It seems that I haven't used this thing since the win' 90s. I can cancel it like this: open the book table, find the subkey branch of HKEY _ local _ machine \ software \ Microsoft \ Windows NT \ Current Version \ AE Debug, double-click the Auto key name below it, change its "numerical data" to 0, and finally press F5 to refresh the setting to take effect, thus canceling its operation. Following this idea, we can cancel all options with debugging function, such as memory.dmp that appears when the screen is blue, and "My computer → Properties → Advanced → Settings → Write debugging information → Do not select" and so on.

8. Remember to report the error, KAO! This thing makes me look like a free tester of Microsoft: click Control Panel-> System-> Advanced-> Lower right corner-> Error Reporting-> Disable Error Reporting-> OK!

9. Remove the waiting time for disk scanning.

Windows XP shut down before 9, and it takes 10 seconds to start disk scanning after restarting. If you think 10 second is too long, let it go for 0 second! Press Start → All Programs → Accessories → Command Prompt, and enter "CHKNTFS /T:0" at the prompt, so you don't have to wait that long 10 second next time.

10, shortening the startup time.

I suggest you use the Bootvis software released by Microsoft, which can automatically optimize the system and shorten the startup time. Just select "Optimize System" in "Tracking" and restart. In addition, the MsConfig installer built into Windows XP can reduce the number of programs loaded at startup, thus shortening the startup time. When operating, just enter "msconfig" and then make relevant settings through "Start".

Second, the slimming plan

1, 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.

2. Delete the driver.cab file in the driver backup: %windows%\driver cache\i386 directory, usually this file is 76M.

In fact, Microsoft's help can't help you. I don't have the habit of reading help, so it is a kind of harm for me to put things in the %windows%\help directory, hehe. . . Kill them all, nearly 4xM.

4. You will be surprised to find that %windows%\ has many directories like $ ntuninstallq311889 $. Don't think that Gates gave you a gift package and killed them all. 1x-3xM.

6. Uninstall uncommon components: use Notepad to modify \%windows%\inf\sysoc.inf, use the find/replace function, enter and hide in the find box, and replace all with blanks. 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、? Except under \windows\ime? Enter the law, 8xM. You can delete it. Don't kill everything you use.

8. Space is really tight. Turning on the compression function of NTFS will reduce the space by 2x%, but I wonder what NTFS is? If it works, you might as well try it.

9. Turning off system restore is a disaster for people like me who often download test software. Right-click My Computer on the desktop, select Properties, find System Restore, and select Turn off System Restore on all drives. Hehe, it can save space again.

10, automatically close the program that stops responding.

In the Windows XP operating system, we can modify the registry, so that when Windows XP detects that an application stops responding, it will automatically shut down without manual intervention. To realize this function, please click "Start → Run" to enter RegEdit, open the registry editor and change its key value to 1.

1 1. Turn off the hibernation function.

Hibernation support only needs to go through the control panel->; Power options-> Hibernation, just remove the check in front of "Enable Hibernation", haha, so that 5 12MB hard disk space can be freed up again. This is a lot of money for a 20G hard disk.

Windows XP Weight Loss Acceleration Series-Accelerated Articles

Last time, I introduced some methods to lose weight, and now I introduce some commonly used and effective acceleration methods.

Due to the different computer hardware and software configurations, the acceleration scheme is differentiated according to the memory size. Please determine the acceleration scheme according to your own memory size. Please refer to the general optimization scheme to optimize your system before choosing. Then optimize your system according to the special optimization scheme.

General optimization scheme

The general optimization scheme can be applied to all system configurations. It is recommended that you use the general optimization scheme for optimization before using the following optimization scheme. Introduction of optimization scheme:

Registry class:

1. Enable CPU L2 Cahce: hkcu _ local _ machine \ system \ current control set \ control \ session manager \ memory management, Create a new Dword value: SecondLevelDataCache, and modify this value (using 10 base when filling) to the size of your CPU's L2 cache.

Introduction of L2 cache size

AMD Series Duron 64 KB K6-3 Thunderbird Athlon XP 256 KB K6-2 Athlon 5 12 KB

Intel Series Celeron 2 128kb P2 Mobile P3e (EB) P4 Willamette 256kb P2 P3 (Katmai) P4 (Northwood) 5 12kb.

For example, according to the above table, if the L2 cache of the CPU is 256KB, modify the Dword value to 65438+256 (decimal).

2. Let IE use multi-thread to download web pages: registry subkey: HKEY _ current _ user \ software \ Microsoft \ Windows \ current version \ Internet settings, and create a new double-byte value item "MaxConnectionsPerServer" to determine the maximum number of simultaneous downloads. Generally, 5-8 connections are better. In addition, for the HTTP 1.0 server, a two-byte value item named "Maximum number of connections per 1 _ 0 server" can be added, and its value is also the maximum number of simultaneous downloads.

Driver category:

1. If it is an Intel 8XX chipset, you must install the Intel Application Accelerator. After installation, the system optimization is obvious. This thing can be downloaded from Intel official website.

2. If the motherboard is not an Intel chipset, it is essential to install the corresponding patch. For example, VIA's 4in 1 program and so on.

3. Try to use drivers who have passed WHL certification. The driver has passed the certification of Microsoft Hardware Lab and has great advantages in stability/compatibility.

Other categories:

1. startup acceleration: Although the startup speed of WindowsXP has been greatly improved, there is still room for acceleration. Download Bootvis.exe file from Microsoft website, start it, and then select Tracking-Optimization System in the menu. At this point, the system will prompt whether to restart, select Start, and don't touch anything after restarting the login. After a while, a dialog box will pop up automatically, which means system analysis. Don't do anything, and you can only operate your system after the analysis is completed. The analysis time is a little long, please wait patiently.

2. Use a fixed virtual cache: It is recommended to set the maximum and minimum values to 382M, regardless of the size of physical memory.

3. Ensure that the memory usage takes precedence over the program, and the CPU plan takes precedence over the program. Open the system properties, open the Advanced tab, click the Settings button in the Performance column, open the Performance Options dialog box, then open the Advanced tab, select a program in the Processor Plan column, select a program in the Memory Usage column, and then confirm to quit.

Special optimization scheme

Above 512m 256m-512m128m-256m

96m- 128m64M-96m is less than 64M.

Group acceleration scheme greater than 5 12M.

The memory capacity of 5 12M is enough for WindowsXP. Even if all special effects are turned on, the system will not feel sluggish, and there is no need for specific optimization. Just refer to general optimization measures.

256m-5 12m group acceleration scheme.

If your memory size is between 5 12M and 256M, the effect of WindowsXP running on your system should be similar to that of 5 12M memory group. The only difference is that if several large-scale applications are running at the same time, the system of 5 12M memory group will be smoother. In general, there is no need to do any optimization. If you feel the need for optimization, you can refer to the next group of optimization schemes.

128 m-256 m group acceleration scheme

This optimization scheme is also applicable to the above two groups.

Optimization scheme: Because this group of memory is not very large, sometimes the system will always use virtual memory. In order to avoid the premature damage of hard disk caused by continuous reading, we have to take some measures to reduce the occupancy rate of memory by system programs. ...............

96m 96M-128M group acceleration scheme.

The optimization scheme of this group is based on the optimization scheme of the previous group, and the optimization scheme of this group can only be applied after being optimized according to the optimization scheme of the previous group.

Optimization scheme: the memory of this group is relatively small. Although it is a bit difficult to run WinXP at this capacity, it can still be run after some optimization, instead of running. This aversion to optimization is still based on fewer special effects ...........

Acceleration scheme of 64M-96M group.

To use the optimization scheme of this group, the optimization schemes of the last two groups must be used first, otherwise they cannot be used.

Optimization scheme: this group of memory is very small. To use WindowsXP smoothly in this group, all special effects must be turned off. Although the system is not very beautiful after turning off the special effects, in order to make you use your WinXP smoothly, there must be a little price, and the price is to turn off all the special effects. ...

Acceleration scheme for people under 64M.

Don't install WindowsXP unless you can tolerate extremely slow speed! !

Improve the startup and shutdown speed of XP.

1. Open the registry.

Go to [HKEY _ Local _ Machine \ Software \ Microsoft \ Windows \ Current Version \ Run] to delete unnecessary startup items. For example: kugoo, 372 1, qq, Doodle Acceleration, realone, msn, etc. (the most important one).

2. Control Panel-Administrative Tools-Services Disable unnecessary windows services, such as windows' own burning function, messenger, network login, automatic update, wireless zero configuration, computer browser ............................................. (very important).

3. Start-Accessories-System Tools-Defragmentation

Remove the debris from.

4. Go to the Prefetch folder under c:\windows and delete all files under it!

5. Reduce the desktop icon and try to start the software from Start-Program. Or create a folder on the desktop to move the icon into the category, and open the folder first when starting.

6. The desktop is the background image. The size should not exceed 300kb.

7. My Computer-Properties-Advanced Initial Settings

Select tuning for best performance.

8. Add physical memory

9. Start running cmd.

Enter sfc to repair the protected system file.

10. Press del to change the bios at startup.

Insert the CD into the installation disk to start the system.

Perform repair installation (the system needs to be reactivated, otherwise it can't be used)

Microsoft plans to speed up the shutdown.

/html/ 1/6/dlid = 13566。 dl typeid = 1 & amp； pn = 0 & amp。 Hypertext markup language

1. Start running msconfig, press enter, start, check antivirus software, firewall, input method ctfmon, remove the other three boxes, and confirm, close and restart the computer.

2. Download the accelerated shutdown patch, and then directly import it into the registry. When shutting down in XP, the system will send a message to the running programs and remote servers, telling them that they should shut down the system and wait for the response before the system starts to shut down. To speed up the shutdown, you can set the task to end automatically first. First, find HKEY _ Current _ User \ Control Panel \ Desktop, and set the key value of AutoEndTasks to 1. Then there is a "HungAppTimeout" under this branch, and its value is changed to "4000 (or below), and the default is 50000; Finally, find HKEY _ local _ machine \ system \ current control setting control \, and also set WaitToKillServiceTimeout to "4000"; Setting the shutdown speed in this way is obviously much faster.
