In the Windows XP operating system, this setting enables Windows XP to automatically close an application when it is diagnosed that it has stopped, without troublesome manual intervention. To realize this function, click Start → Run, enter "RegEdit" to open the Registry Editor, find HKEY _ Current _ User \ Control Panel \ Desktop Branch, and set the key value of AutoEndTasks to 1.

Second, speed up the startup and reduce the recovery time.

Maybe Windows9X and WindowsXP*** are stored in your computer, and users can completely reduce the time to display the operating system list when WindowsXP is started. Please click Start → Run, enter msconfig and open the system configuration utility →"BOOT. INI and change the timeout setting to the time you want. If you are a loyal user of Windows XP operating system, I suggest that you can set the startup waiting time to 5 seconds. Or right-click my computer → Properties → Advanced, and click Settings during startup and recovery to set the time for displaying the operating system list, or click Edit to manually edit the startup option and change timeout=30 to timeout=5.

Third, how to reduce the waste of disk space

During the operation of Windows XP operating system, files with suffixes such as tmp, bak, log, old, txt, etc. It often happens. These files can actually be safely deleted, even bmp files in the Windows directory, if you don't like the wallpaper that comes with Windows XP. You can completely delete these files.

I also suggest that you delete the files in the Windows\temp directory of Windows XP operating system, which are redundant files left over from the installation of application software. Another point is the small files on the hard disk. Please gather them together as much as possible, and then merge them into a large file with compression software such as WinZip to reduce the waste of disk space.

Fourth, optimize the page file.

At present, the memory configuration of mainstream computers has been upgraded to 128MB, but 128MB is far from meeting the requirements for the huge WindowsXP operating system and various software with more and more powerful functions and occupying more and more system memory resources. At this time, the page file used by WindowsXP (the function is equivalent to what we often call virtual memory) can play a role. It sets a part of the hard disk space as virtual memory, thus expanding the available "memory" space of the computer to meet the running requirements of the program.

Because Windows XP dynamically allocates page files, Windows XP will constantly expand the space on the hard disk to meet the requirements of program running. This will lead to the decrease of system working efficiency and the delay of system response. Therefore, the virtual memory is set to static. Microsoft's suggestion is that the minimum page file should be the current system memory capacity plus 12MB (RAM+ 12MB). For machines with 128MB memory and machines with 5 12MB memory, the rules for optimizing performance are definitely different. For the machine with 128MB, the page file setting can be calculated according to the following formula: memory space size × 1.75. For machines with memory of 256MB or more, the page file settings can be calculated according to the following formula: memory space size × 1.5. Only in this way can the operating system copy all the contents of the memory to the hard disk before it crashes or crashes.

Specifically, right-click my computer → Properties → Advanced, click Settings → Advanced in performance options, click Change in virtual memory options, select custom size, change the page file size, and change the initial size to be consistent with the maximum value. When you are finished, click Settings.

Verb (abbreviation of verb) visual effect

As we all know, the menu effect of Windows XP is much more beautiful than that of win9x and other brothers, but for users with small memory, it is too gorgeous and takes up too much memory (the author's memory of 256MB can only basically meet the demand). So how to modify it? Please follow me:

1. Click Start → Control Panel, and select Performance and Maintenance → Adjust visual effects in the classified view of the control panel. At this point, the performance options window will pop up, where you can select Adjust to Best Performance to remove all animation effects from the menu. You should feel that the speed has improved significantly. If you still feel that it is not fast enough, please look down.

2. Next, please click Start → Run, enter "RegEdit" to open the Registry Editor, find the branch of HKEY _ Current _ User \ Control Panel \ Desktop, double-click the key name of the right window, and the value range of this item is 0 ~ 100000 (in milliseconds), and then change the default value to 0.

Six, set the hard disk working mode

Nowadays, the hard disks used by computer enthusiasts are much larger than in the past (because they are cheap), with 30G and 400G at every turn. Large hard disks generally support DMA mode. If you are sure that your hard disk supports DMA mode, you can use DMA mode instead of traditional PIO mode, which can improve the transmission speed of hard disk and reduce the utilization rate of CPU, thus improving your system performance. Specifically, click Start → Control Panel → Performance and Maintenance → View Basic Computer Information → Device Manager → "IDE ATA/ATAPI Controller → IDE Channel → Properties → Advanced Settings, and select DMA in transfer mode.

Seven, mail program Outlook Express

The following tips can reduce the chances of OE making mistakes. In the Outlook Express interface, open Tools → Accounts on the menu, select your account, and then select Properties → Advanced to make the server timeout the longest (five minutes).

8. Handle the situation that the operating system security log is full.

1. Open the event viewer first. Click Start → Settings, then click Control Panel, double-click Administrative Tools, and then double-click Event Viewer.

2. In the console tree that appears, right-click the security log and then click Properties.

3. Then, on the General tab, click the event that has been overwritten for more than n days (7 days ago by default) or do not overwrite the event (manually clear the log).

4. Change the size of the log file. The default value is 5 12KB.

5. Next, click Start → Run, then enter the "RegEdit" command to open the registry editor, and find HKEY _ local _ machine \ system \ current control set \ control \ LSA branch. Right-click the "CrashOnAuditFail" branch and choose to create the "REG_DWORD" type, and assign it to 65438+.

6. After this operation, you need to restart your computer.

Windows XP has tools that we often use, such as disk cleaner, so what are their names and where are they hidden on the hard disk? The author will dig them out, so that when you use these tools in the future, you don't have to find a place step by step. Just click "Start → Run" and enter the program name.

1. How to use ClearType antialiasing function of Windows XP?

If Windows XP is installed on the laptop you are using, if you pay a little attention when processing documents, you will find that the edges of words and fonts on the screen are uneven and annoying. So how to solve this problem? In fact, Microsoft has set ClearType anti-aliasing function for WindwoXP. You can solve the above problems well by turning on this function.

How to open the ClearType function:

(1) Select Start/Control Panel/Display;

(2) In the Display Properties dialog box, select the Appearance tab, and then click the Effect button. In the Effects dialog box, you can turn the ClearType feature on or off.

If you are already using XP and want to see the effect of ClearType first, you can turn on the magnifying glass function in XP, and then slide the cursor over some text to test the effect.

Second, how to open NetBEUI communication protocol in Windows XP?

NetBEUI communication protocol should be the product of Windows 95/98 era. If some machines in your company are upgraded to Windows XP, you will find that NetBEUI communication protocol has disappeared in Windows XP. However, in some LANs, due to the initial network planning, NetBEUI is needed to access some or all computers in the network. Is it necessary to go back to the Windows98 era? At this time, you don't have to worry. NetBEUI is still on the Windows XP CD, but there is no preset protocol. If you need this communication protocol, you must * install it yourself.

Setting method:

(1) put it into the Windows XP installation CD, and copy Netnbf.inf to C: Windows INF in the "ValueaddMsft et etbeui" directory;

(2) copy Nbf.sys to c: windows system 32 drivers;

(3) Press "Start/Control Panel/Network Neighborhood", select "Network Connection", right-click "Local Connection" (that is, the connection you are currently using), and select the content;

(4) In the "General" item, select "Installation", select "Communication Protocol" and press "Add". At this point, you can see the NetBEUI Protocol project (this project is not available). After selecting NetBEUI, click OK.

Third, let Windows XP quickly shut down and restart.

It is very slow for Windows XP operating system to save the current settings when it is shut down or restarted. In fact, you can try to bypass the save settings screen and quickly shut down or restart.

Press Ctrl+Alt+Del to open the window task manager, click the "Shutdown" command, hold down the "Ctrl" key in the pop-up menu, and click the "Shutdown" or "Restart" command to skip the screen of saving settings and realize instant shutdown or restart.

However, using this closing method, you will not be prompted to save the file or close the window again. Do not use this method if you still have unsaved files.

Fourth, batch conversion of image formats.

In Windows XP, if there is no better conversion program, we can convert an image file in BMP format into an image in JPG format through a drawing program. However, the conversion efficiency is very low, and only one image file can be converted at a time. In fact, there is another method of batch conversion.

First, copy the BMP pictures that need to be converted to the "Picture Collection" folder, then select these picture files, click the right mouse button, and select the "Send to/Mail Recipient" command in the shortcut menu that pops up. Next, a window "Send photos by email" will pop up. Select the "Reduce all photos" option in this window, select the size of the photos, and then click the "OK" button. Next, Windows XP will convert these images in BMP format to a smaller JPG format, and a "Send Email" window will pop up. Finally, just save these image attachments in JPG format.

5. Encrypted files (folders)

It is true that files (folders) can be encrypted directly in Windows XP, but there is a premise: the hard disk partition where the files (folders) to be encrypted are in NFTS format. If not, it can be converted into NFTS before operation.

Select the file (folder) to be encrypted, right-click and select the "Properties" command in the pop-up menu. In the pop-up window, select the "Advanced" button to open the "Advanced Properties" dialog box, select the "Encrypt content to protect data" option, and then click "OK" to start. It should be noted that if the file (folder) is encrypted by the above method, it is best to decrypt it before reinstalling the system in the future (the decryption method is similar to encryption, except that the option of "encrypting content to protect data" is removed). Otherwise, after reinstalling the system, files (folders) may not be opened normally.

Six, cancel the waiting time before disk scanning

When using Windows XP, if you encounter unexpected situations such as power failure and crash, Windows XP will automatically scan the disk after restarting the computer. Before the disk scan, the system will give you a countdown time of 10 second for you to choose whether to skip the disk scan. You can also cancel the countdown before disk scanning if you don't want it. Select "Start/All Programs/Accessories/Command Prompt", in the command prompt window, press "CHKNTFS /T:0" and press enter to change the countdown time before automatically scanning the disk to 0 seconds.

Seven, Windows XP is easy to lose weight.

1. Delete file backup

Enter the "Windows\System32\dllcache" directory (hidden directory by default), which stores about 360MB files, which are backups of Windows XP system files. When the system files of Windows XP are replaced, deleted or modified, the system can automatically extract the corresponding system files, thus ensuring the stability of the system. If you have a Windows XP installation CD or have copied the installation files to your hard disk, you can delete the folder.

Note: This folder cannot be deleted directly. You need to enter "sfc.exe/Purge Cache" (space before slash) at the command prompt to delete it.

2. Delete the driver backup

Windows XP comes with a large number of hardware drivers. When new hardware is detected, the system will automatically extract the corresponding driver for installation. In fact, in most cases, we rarely change our hardware configuration, so we can delete the driver backup file when we are sure that all the required hardware drivers have been installed. Enter the "Windows\DriverCache\i386" directory, find the compressed file named "Driver.cab" and delete it. This will free up about 73MB of hard disk space. If the system can't find the driver when installing new hardware in the future, it can be extracted from the installation CD.

3. Delete the unused input method

There are several input methods that we basically don't need under Windows XP, such as Japanese and Korean input methods. The method of deletion is: enter the control panel \ Date, Time, Language and Regional Settings \ Regional and Language Selection, select the language tab, remove the check box in front of "East Asian Language Installation File", click OK, and then delete the unnecessary language options according to the prompts. After restarting, directly delete the three folders "chtime", "imju8_ 1" and "imk6_ 1" (corresponding to traditional Chinese, Japanese and Korean respectively) under the "Windows\ime" folder, which can free up 85MB of hard disk space.

4, empty the system temporary files

In the directory "\ documents and settings \ user name \ local settings \ temp" (hidden directory by default), temporary folders and discarded documents left by software installation are stored, which can release hundreds of megabytes of hard disk space. This method can be used frequently.

Eight, to prevent the taskbar "suspended animation"

The phenomenon of "fake death" in the taskbar is quite common in Windows XP. In addition to installing the official Microsoft patch to solve this problem, you can also turn off the advanced text service to prevent the phenomenon of "fake death" in the taskbar (because enabling the advanced text service will consume a lot of system resources and may conflict with some software, such as handwriting recognition and Chinese keyboard input). The specific method is as follows:

Open the Regional and Language Options window, select the Language tab, and then click the Details button to open the Text Service and Input Language window. Then, click the Language Bar button. In the pop-up window, directly select the option of "Close Advanced Text Service" and click the "OK" button to open the confirmation window. Click "Yes" button to disable the advanced text service, and finally click "OK" to exit.

Nine, delete the redundant administrator account

In Windows XP, there are usually multiple administrator accounts. In addition to the built-in administrator account created by the system itself, there are other administrator accounts. To make the system more secure, you can delete unnecessary administrator accounts.

The first thing to understand is that the administrator account to be deleted must be a user with administrator status, so you should choose the built-in "administrator" account to log in. When the Windows XP login window appears, enter "Administrator" in the user name, and then enter the password to log in.

Tip: The "Administrator" account will only appear when there is no other account except the guest account or when you log in to the computer in safe mode, so you can log in by directly entering "Administrator" in the user name.

1, user account method

In Windows XP, open Control Panel and double-click User Accounts in Classic view. In the window that opens, click the name of the administrator account that you want to delete. In the user account change window that appears, click Delete Account, and then you will be asked to choose whether to keep the files of the administrator account. Click the Save File button to save the files of the administrator account, such as desktop, my documents, favorites, etc. Click the "Delete File" button, and a confirmation window for deleting the account will appear below. Click the Delete Account button to delete the administrator account.

Tip: This skill can only be realized after creating two or more administrator accounts other than the Administrator account.

2. Local users and grouping methods

Type "lusrmgr.msc" in "Start \ Run" to open the "Local Users and Groups" window, right-click an administrator account, select the "Delete" command, and click the "Yes" button in the pop-up deletion confirmation window to finish deleting the administrator account.

Tip: This technique can be applied to cases where there is only one or more administrator accounts besides the "Administrator" account.

X. let the Windows XP taskbar display the current date.

Windows XP taskbar can display not only the time, but also the current date, but if you just installed Windows XP, you will find that the taskbar still only displays the time as before. So how do you display the date? In fact, as long as you drag the taskbar width to two lines, the current date and week will be displayed. However, this is not always effective. If the current date is set to * * *-* * format (for example, 2003- 12-3 1), no matter how wide you drag the taskbar, only the time and week will be displayed, but not the date. At this time, if you want to display the date, please open the control panel, select Regional and Language Settings, click the Customize button in Regional Settings, change the time format in the time property page to tt h:mm:ss or tt hh:mm:ss (the default is h:mm:ss), and then check your taskbar.
