Accelerated startup and shutdown:

① Select "Start \ Run", type Regedit, expand HKEY _ Current _ User \ Control Panel \ Desktop, change the numerical value of the string value "HungAppTimeout" to 200, and then change the numerical value of the string value "WaitToKillAppTimeout" to1000;

② In addition, under HKEY _ local _ machine \ system \ currentcontrolset \ control, the numerical data of the string value "HungAppTimeout" is changed to 200, and the numerical data of the string value "WaitToKillServiceTimeout" is changed to [1000];

③ Use Microsoft Bootvis.exe to optimize the startup speed. We download bootVis.exe from Microsoft official website, decompress and run bootvis.exe, and then select the next startup and drive delay under Trace, after which XP will restart, and the recorded startup data will be generated into a BIN file. Then open this file in "File \ Open" and select the optimization system under Trace.

Tip: This optimization will take a long time, please wait patiently.

Clear unused DLL files in the registry:

Type [regedit] \ [hkkey _ local _ machine] \ [Software ]\[Microsoft]\[Windows]\[ Current Version] \ [Explorer] in [Start] \ [Run].

Add a key [[〔AlwaysUnloadDLL〕]]. The default value is [1].

If the default value is set to [0], this function will be disabled.

Accelerate broadband connection:

Type [regedit] in [Start] \ [Run] \ in [HKEY local computer] \ [Software] \ [Policy] \ [Microsoft] \ [Windows].

Add a key named [[〔Psched〕]

Add a Dword value [[〔NonBestEffortLimit〕] to the right of [[〔Psched〕] in the window, and the numerical data is [0].

"Windows XP Home Edition only"

Accelerated menu display:

Type [regedit] \ [HKEY _ Current _ User] \ [Control Panel] \ [Desktop] in [Start] \ [Run] to change the numerical data of the string value [[〔MenuShowDelay〕] to [0].

After adjustment, if you feel that the menu display speed is too fast to adapt, you can change the numerical data of 【 MenuShowDelay 】 to 【 200 】.

The restart takes effect.

Speed up the automatic update:

Type [regedit] \ [HKEY _ local _ machine] \ [System] \ [Current Control Set] \ [Control] \ [Update] \ to change the numerical data of Dword〔 [Update Mode] to [0]. The restart takes effect.

Load unneeded programs when shutting down startup:

If there are too many programs to run at startup, which will affect the startup speed, first check which files will be run at startup.

Type [msconfig] in [Start] \ [Run] and select [Start].

The program in startup represents the program to be run at startup. If you need to temporarily stop running some programs, just cancel the [X] symbol in [□], and if you want to resume running the program at startup, just add the [X] symbol in [□].

Disable unneeded services:

Type [[〔services.msc〕] in [Start] \ [Run] to open the service window.

For unnecessary services, check the right window and select [Disabled] in [Startup Type]; Then select [Disabled] in [Service Status].

Make full use of the L2 cache of CPU to speed up the overall performance;

In the right window of [Memory Management], type [regedit] \ [HKEY _ local _ machine] \ [System] \ [Control] \ [Session Manager], and change the numerical data of [Second-level data cache] to the same as that of CPU L2 cache.

Example: P4 1.6G L2 cache is 256Kb, and the numerical data is changed to decimal value of 256.

The value of L2 cache is not copied like some irresponsible web pages. For example, the L2 cache of P4 1.6G is 256Kb, but the L2 cache of P4 1.6GA is 5 12Kb.

Readers can find information about L2 CPU cache through the network.

Run the defragmenter when you start the computer:

Type [regedit] \ [HKEY Local Machine] \ [Software] \ [Microsoft] \ [DFRG] \ [Boot Optimize Function] in [Start] \ [Run].

Set the string value [[enable] to [y] equal to on, and set it to [n] equal to off.

Reduce the waiting time for multiple starts:

Method 1: Open the boot.ini file in the C:\ directory with Notepad, change the setting value of the content [[timeout] from the preset 30 (seconds) to the number of seconds to wait, and save it.

Method 2: You can also open the boot.ini option by [Start] \ [Run] \ typing [[MSConfig] to modify the number of seconds.

Method 3: Right-click "My Computer" and select Properties \ Advanced \ Startup and Recovery \ Settings to modify the startup waiting time here.

Turn off the built-in CD burning function in XP:

If you don't plan to use this function, you can turn it off, which will speed up the use of Nero burning software, because the burning system of Windows XP is provided by Roxio Company (that is, the same company as Easy Cd Creator).

In [control panel] \ [administrative tools] \ [services], select [IMAPI CD-Burning COM service] \ [startup type] \ and select [disable] in the right window.

Automatically close the stop response program when shutting down:

Type [regedit] \ [HKEY user] \ [. Default] [Control Panel] in \ [Start] \ [Run] \, and change the numerical data of [Automatically End Task] to [1] in the right window of [Desktop].

Just log off or restart.

Remove Windows Messenger:

Open the sysoc.inf file under X:\WINDOWS\inf with WordPad first.

X = (X = (the volume where XP is located)

Put the content [msmsgs = msgrocm.dll, ocentry, msmsgs.inf, hide, 7].

Changed to [msmsgs = msgrocm.dll, ocentry, msmsgs.inf, 7].

Archive and exit

Then, after [Control Panel] \ [Add or Remove Programs] \ [Add/Remove Windows Components] \ uncheck [Windows Messenger]\[ Next] \ [Finish], it was successfully removed.

Stop the "Out of Disk Space" notification:

When the capacity of the disk drive is less than 200MB, Windows XP will issue a notice of "insufficient disk space".

To stop this feature, you can change the login file by following the steps below.

In [Start] \ [Run] \, type [regedit] \ [HKEY Local Machine] \ [Software] \ [Microsoft ]\[Windows]\[ Current Version] \ Add the password name [[Resource Manager] under [[Policy] (if it already exists, please don't add it) \

Numerical data defaults to [1] = stop notification, and numerical data defaults to [0] = start notification.

Turn off automatic windows updates:

Click the right mouse button [My Computer] \ [Content] \ [Automatic Update]

The numerical data of [[〔MaxConnectionsPerServer〕] is [000000a], that is, decimal [10].

Restarting the computer will take effect.

[repost] My Road to WinXP Optimization [Recommended]

Repost] My Road to WinXP Optimization [Recommended]

In order to achieve this goal, we mainly start from four aspects:

1, reducing disk space occupation.

2. Terminate infrequently used system services.

3. Security issues

4. Other skills

First, do you really want to activate XP? No. . Exactly, do you want to be able to upgrade on the ms site? If the answer is yes, let's discuss the installation first. At present, I recommend the popular versions of V4, V5 and V6, especially V5 and V6. There was a serial number problem during installation. I suggest you calculate it on the computer first, and then install it with this serial number. Usually XP installed in this way can be updated at the MS site for free.

It doesn't matter if you have installed XP, but the serial number you use is the one that everyone in the room uses everywhere. We will say later that repackaging with sysrep will solve the problem of serial number replacement.

I assume that you have installed XP, come on baby ~ ~

First, slimming action

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.

3. 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. Later, after upgrading, you will find that %windows%\ has many directories similar to $ ntuninstallq311889 $. Kill them all, 1x-3xM.

5. There happens to be win2000/server in the hard disk. By the way, point all the pagefile.sys files to one place: control panel → system → performance → advanced → virtual memory → change. Note that the key "Settings" will take effect.

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. Delete the input method 8xM that is not used under \windows\ime. I reinstalled my zrm input method, hehe.

8. If the space is really tight, enabling the compression function of NTFS will also use 2x% less space, but I didn't do 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, there are several files, which are quite large and useless. . . . Forgot the name: (,the newly installed system can use the search function to find files larger than 50M, and you should be able to find them.

If you can follow the above process, your original XP of 1.4G can be completely reduced to below 800.

Second, accelerate 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 starts the registry editor and finds HKEY _ local _ machine \ system \ currentcontrolset \ control \ SessionManager \ memory management \ prefetch parameter. There is a key that can 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.

5. It is said that a system of XP serves Qos, and this scheduling takes up a certain amount of network bandwidth, which is unbearable for a penniless person like me. 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 limit the reserved bandwidth. After completing and applying the above modifications, users can see the "QoS Packet Scheduler" in the General Properties tab of the Network Connection Properties dialog box. 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. List of services I terminated and related explanations.

1) Alarm error alarm

2) automatic update windows automatic update

54) Windows Management Instrumentation driver extension is closed.

55)windows Time Service

56) Wireless zero configuration wireless network, occasionally not used.

57)WMI perfromance adapter is closed!

Some services here were shut down at the beginning, but I forgot to list all the closed services in the current system. You should handle it according to your own situation.

Third, am I safe?

Many things aside, the basic enjoyment of * * * still has to pass:

Modify the registry to the following two styles:

Remove * * * enjoyment

——————————————————————

Windows registry editor version 5.00

[HKEY _ LOCAL _ MACHINE \ SYSTEM \ current control set \ Services \ lanman server \ parameters]

" AutoShareServer " = dword:00000000

" AutoSharewks"=dword:00000000

——————————————————————

Delete IPC$ management

——————————————————————

Windows registry editor version 5.00

[HKEY _ LOCAL _ MACHINE \ SYSTEM \ current Control set \ Control \ Lsa]

" restrict anonymous " = dword:0000000 1

——————————————————————

Or save the above two as. REG files, and then double-click Import.

By the way, block the shameless 372 1 and add it to the hosts file:

127 . 0 . 0 . 1 cnsmin . 372 1 . com

127.0.0. 1

Fourth, other skills.

1. The Add Copy to .../Move to ... function moves to the right mouse button.

—————————————————————

Windows registry editor version 5.00

[HKEY _ LOCAL _ MACHINE \ SOFTWARE \ Classes \ all filesystemobjects \ shellex]

[HKEY _ LOCAL _ MACHINE \ SOFTWARE \ Classes \ all filesystemobjects \ shellex \ context menu handlers]

[HKEY _ LOCAL _ MACHINE \ SOFTWARE \ Classes \ all filesystemobjects \ shellex \ context menu handlers \ Copy To]

@ = " { c2fbb 630-297 1- 1 1d 1-a 18C-00c 04 FD 75d 13 } "

[HKEY _ LOCAL _ MACHINE \ SOFTWARE \ Classes \ all filesystemobjects \ shellex \ ContextMenuHandlers \ Move To]

@ = " { c2fbb 63 1-297 1- 1 1d 1-a 18C-00c 04 FD 75d 13 } "

————————————————————————

Save the above as an add.reg file, and then double-click Import.

2. Error in closing the report, 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!

3. Ungroup display: right-click the blank area of the taskbar and select Properties from the pop-up menu. In the pop-up window, uncheck "Group similar taskbar buttons" and confirm.

4. Retrieve the classic login window. Although the default login interface of WinXP is beautiful, if you want to log in with an unlisted user, you will find that there is no way to start. The way to change back to the classic window is to click Start → Control Panel → User Account → Change the login or logout mode of users → Cancel using the check mark in front of the welcome screen, and finally click the application options.

5. Set shortcut keys for your most commonly used input method: click Start → Control Panel → Regional and Language Options → Select Language → Details → Key Settings to find your own input method, and click Change Key Order → Select shortcut keys here.

6. When the computer is turned off, the unresponsive task will automatically end. The key value of "AugoEndTasks" in the registry: HKEY _ Current _ User \ Control Panel \ Desktop changed to "1".

7. Turn off automatic update: right-click my computer, click Properties, click automatic update, and then select Turn off automatic update in the notification settings column. I will update my computer manually.

8. Reduce the waiting time for scanning the startup disk, start → run, and type "chkntfs/t:0".

Then connect to the ms site and upgrade once, even if the optimization is basically completed. For XP, you can use many internal commands to view optimizations. For example, tasklist.exe/SVC can see the actual usage of system services.

Optimizing a system is very troublesome. So we save it and use Ghost to generate a. GHO file so that we can show it to others. Before Ghost, you must do one thing, clear the system hardware, registration and other information, otherwise cloning to different computers will not start. Look for the sysprep.exe file in the Deploy.cab of the Winxp installation disk.

Execute sysprep.exe and select "repackage". You can choose "activate in advance" in the mark below, or you can choose whether to shut down or restart after packaging is completed. After the package is completed, we use GHOst to start from the system disk and use Ghost to generate the backup. Gho mirror, backup complete!

After executing the package and restarting, XP will let us enter the serial number. The method of modifying the serial number mentioned at the beginning of this article is like this.

A collection of the latest application skills of Windows XP.

A collection of the latest application skills of Windows XP.

1. resume EXE file association

EXE file association error is very troublesome,

Because this situation is mostly caused by viruses, and the main files of anti-virus software are EXE files, since the EXE files are wrongly associated, how to run anti-virus software? Fortunately, XP provides us with a command line tool in safe mode, which can be used to solve this problem.

Input: Assoc. Exe = exe < enter >, and the screen will be displayed. exe=exefile”。 Now close the command prompt window, press Ctrl+Alt+Del to bring up the Windows Security window, press the "Shut Down" button, and select the "Restart" option. After starting Windows in normal mode, all EXE files can run normally!

3. Change the Windows XP serial number

After installing Windows XP,

Maybe for some reason, you want to change the serial number on the installed Windows XP. What should you do? Use the activation wizard to meet your requirements. Before starting, it is strongly recommended that you restore the system to its original point before modifying it, so as to avoid unnecessary troubles caused by misoperation.

Click Start → Run, enter regedit, open the Registry Editor, navigate to HKEY _ Local _ Machine \ Software \ Microsoft \ Windows NT \ Current Version \ WPEvents, right-click the OOBETimer on the right, then select Modify, at least one byte, and confirm to save.

Click Start → Run, enter% systemroot% \ system32 \ oobe \ msoobe.exe/a, Select to activate by phone, then click Next, click Modify Serial Number, enter a new serial number, and then select Update. If you return to the previous screen, choose to activate and restart later, and repeat the previous steps until the modification is successful and reactivated. Click OK to install SP 1.

If you can't restart after installing SP 1, press F8 when starting, choose to use the last known good configuration, and then repeat the above process. This method is applicable to Windows XP Professional.

4. Add EFS option to the shortcut menu

The Encrypted File System (EFS) equipped with Windows XP can help you encrypt files and folders stored on NTFS disk volumes. If you have added this file encryption/decryption option to the shortcut menu, when the user right-clicks a file or folder stored on an NTFS disk volume, the encryption or decryption option will appear in the shortcut menu that pops up later. Please note that Windows XP Home Edition (Home Edition) does not provide EFS function.

To add EFS options to the shortcut menu, please perform the following steps in turn: enter regedit in the run dialog box and expand the registry to the following subkeys: HKEY _ local _ machine \ software \ Microsoft \ Windows \ currentversion \ exporter \ advanced, On the edit menu, point to new, click DWORD value, enter EncryptionContextMenu as the variable name, and assign the variable as 1. To ensure that the registry is modified, you should have an administrator account on your computer.

5.XP process desktop vulnerability solution

Windows XP provides remote desktop function, but it has been proved that there are design flaws, which may lead attackers to obtain the account information of the remote desktop of the system and help them to attack further. After the connection is established, use Windows XP Remote Desktop to send the account name to the connected client in clear text. The account name sent is not necessarily the user account of the remote host, but the most commonly used account name of the client, and the sniffer program on the network may capture these account information.
