1. Restore EXE file association
An error occurred while associating the EXE file,
In this case, most of them are caused by viruses, and the main files of anti-virus software are EXE files. How can we run anti-virus software since there is an error in the association of the EXE files? Fortunately, XP provides the command line tool in safe mode for us to use. You can use the command line tool to solve this problem.
In safe mode, enter assoc <space>. EXE = exefile <press enter>. Then, cmd.exe = exefile is displayed on the screen ". Close the Command Prompt window, press CTRL + ALT + DEL to bring up the "Windows Security" window, press the "Shut Down" button, select the "restart" option, and start Windows in normal mode, all the EXE files can run normally!
3. Change the Windows XP serial number
After Windows XP is installed,
For some reason, you may want to change the serial number on Windows XP. What should you do? The activation wizard can meet your requirements. We strongly recommend that you restore the origin of the system before modification to avoid unnecessary troubles caused by misoperations.

Click Start> Run, enter regedit, press enter, open registry editor, locate HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ WindowsNT \ current version \ wpaevents, right-click oobetimer on the right, then select modify. Modify at least one byte to save the modification.

Click Start> Run, enter % SystemRoot % \ system32 \ oobe \ msoobe.exe/a, activate by phone, click Next, and modify the serial number, after entering the new serial number, select "Update". If it is returned to the previous screen, activate it later and restart it. Repeat the previous steps until the modification is successful and reactivate it. Click OK to install SP1.

If you cannot restart after installing SP1, press F8 at startup, select "Last correct configuration", and then repeat the above process. This method is applicable to Windows XP Professional.

4. Add the EFS option to the shortcut menu

Windows XP's encrypted file system (EFS) helps you encrypt files and folders stored on NTFS disk volumes. If you have added the file encryption/Decryption option to the shortcut menu, When you right-click a file or folder stored on an NTFS disk volume, the encryption or decryption options will appear in the shortcut menu that will pop up later. Note that Windows XP Home Edition (Home Edition) does not provide the EFS feature.

To add the EFS option to the shortcut menu, perform the following steps in sequence: Enter Regedit in the "run" dialog box, and expand the registry to the sub-key below: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ exporer \ Advanced, point to "new" on the "edit" menu, click "DWORD Value", and enter encryptioncontextmenu as the variable name, and assign this variable to 1. To ensure that the registry is modified, you should have an administrator account on your computer.

5. Solutions to Windows XP desktop Vulnerabilities

Windows XP provides the Remote Desktop function. It has been confirmed that there are design defects, which may cause attackers to obtain the account information of the System Remote Desktop and facilitate further attacks. When the connection is established, use Windows XP Remote Desktop to send the account name to the client connected to it in plain text. The account name sent is not necessarily the user account of the remote host, but the account name most frequently used by the client.ProgramThese account information may be captured.

Solution: Download the corresponding patch on the Microsoft homepage and temporarily stop using the Remote Desktop. Right-click my computer and choose Properties ", in the pop-up window, select the "remote" tab, deselect the check box before the "allow users to remotely connect to this computer" check box, and click "OK.

6. Create a password to reset the disk

The password is very important in Windows XP, but what if you forget that you cannot log on? If you create a "Password Reset disk", the problem will be solved. Open a user account in the control panel, click your account name, and click "Do not forget password" under "related tasks" on the left side of the window, and select "Next, if you are prompted to require a disk, prepare a blank disk and insert it into the drive. continue to the next step. after entering the password of the current account (figure 4), click "Next" to create the disk, if you forget your password later, click the user name and enter the password when the welcome screen appears. If you forget the password, it will show "Have you forgotten your password ?" Message, click "use password reset disk" to start the "Password Reset wizard", follow the instructions in the "Password Reset wizard" to create a new password and log on with the new password, then, store the password reset disk in a safe place for future use when you need to reset the password. You do not need to create a new password to reset the disk.

7. Solve DirectX errors

If you frequently receive DirectDraw error messages during computer operations,
Then you can try to apply the DirectX diagnostic tool to solve the problem. Choose "accessories"> "System Tools"> "system information" from the Start Menu. On the displayed program interface, click "Tools"> "DirectX diagnostic tools" (figure 5) on the menu bar. In the displayed window, switch to the "display" tab to view the "DirectX function" project, test dircetdraw and direct3d on the current device respectively. If any problem exists, disable this function.

8. Use the Added Disk Tool

In XP, the familiar Scandisk is gone, and many people are not comfortable with it. In fact, Windows XP already contains an enhanced disk tool: Check disk. Therefore, Scandisk does not need to exist. If you want to use check Disk: open my computer, right-click a drive and select "properties ". On the "Tools" tab, click "check now" under check errors ". If you want to check disk partitions from the command line, you can use the chkdsk C: format.

9. Solutions for forgetting the Login Password

XP strictly audits user security. If you forget the password you set, do not think that you can select "cancel" like Windows 98 to enter the system, I believe that those who have installed Windows XP are very clear about this. Because you cannot access the system without a logon password, many of your friends have chosen to reinstall Windows XP. However, this method is cumbersome, time-consuming, and labor-consuming.

As you know, the security account manager (SAM) mechanism is used for security management of user accounts in Windows 2000/XP, the Security Account Manager manages Accounts by using Security Identifiers. Security Identifiers are created at the same time when an account is created. Once an account is deleted, the Security Identifiers are also deleted. The Security ID is unique. Even if the user name is the same, the Security ID obtained at each creation is completely different. Therefore, once an account is deleted, its security id no longer exists. That is, using the same user name to recreate the account will also be assigned different security IDs without retaining the original permissions.

The security account manager displays the % SystemRoot % \ system32 \ config \ SAM file. The Sam file is a user account database of Windows NT/2000/XP. All user login name, password, and other information will be saved in this file. After knowing these solutions, we also created: before the system starts, insert the boot disk, enter c: \ winnt \ system3 \ config \, and rename the Sam file using the Ren command, or run the del command to delete the Sam file and restart the computer. After renaming or deleting the Sam file, try to log on to the Administrator. The password is blank.

10. font installation optimization

Some friends need to install a variety of fonts, but some fonts are very large, especially Chinese fonts, usually around 10 M. Once too many fonts are installed, the system disk will be bloated. In fact, from Win98 to WINXP, you can make some optimizations during installation. The effect is that you no longer copy the new font to the system disk.

Taking WINXP as an example, we create a directory on a blank drive: newfonts (name, drive name can be set), and then put all the fonts to be installed into this directory, enter fonts in "start"> "run", open the fonts directory, open "file"> "install new font" in sequence, and find D in the displayed dialog box: \ newfonts directory, remove "√" (figure 6) before "Copy font to fonts folder", select the font to be installed, and click OK.

11. Sound prompt switch key

When you enter a large number of English/Chinese characters,
You may often encounter frequent input errors due to incorrect press and switch keys, reducing your work efficiency (especially fast and blind ). If sound prompts are set for the switch key, this problem can be effectively avoided. On the "control panel", double-click the "Auxiliary Function options" icon. In the displayed dialog box, view the "keyboard" tab, and select the "use switch key" check box in the "switch key" project, click "OK" to enable the setting to Improve the efficiency (figure 7 ).

12. Automatic time correction

What if the clock in Windows XP is suddenly unavailable? I believe most people will use manual methods to re-calibrate the time. Unfortunately, no matter how careful we are, it is impossible to achieve accurate calibration by manual means. To accurately adjust the clock, we can use the following method:

Double-click the system clock icon in the tray area of the system taskbar, open the "Internet time" tab page, select a standard time server, and click OK, the system automatically connects to the Internet, and automatically compares the system clock in the computer with the clock on the specified server. If it finds it is inaccurate, it can be automatically adjusted. However, you must ensure that your system does not have a firewall installed.

13. XP can also be scanned by disk

I don't know how many disk scanning functions are not provided in Windows XP, which makes disk sorting inconvenient. To solve this problem, after painstaking research, we finally found a solution.

In "my computer", right-click the partition for scanning and detection, open its properties dialog box, switch to the "Tools" tab, and click "Start Check" in the "check error" area, in the subsequent dialog box, select "automatically repair file system errors" and "scan and try to recover bad sectors" (figure 8), and click "start.

14. Disable the use of IE6 to download files

Sometimes we need to disable the IE File Download function, but we have never been able to use the system settings. In fact, if we make some modifications to the Registry, we can meet your requirements. Open the Registry Editor, find HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Internet Settings \ Zones \ 3, find the DWORD Value 1803 on the right, and double-click to modify it to 3. Restart IE to see if the download is sufficient? To cancel the limit, you only need to restore the value of DWORD to 0.

15. Check System compatibility with a CD

Windows XP, as the latest operating system for personal installation and use, often encounters incompatibility during the installation process on some old computers, resulting in the installation process being forced to end in half. To avoid this problem, we can check the system compatibility with the installation CD before installing Windows XP.

When you place the installation disc into the optical drive, the welcome page is generally automatically displayed. (Note: if the disc is not allowed to run automatically, we can execute setup in the disc. EXE command can also be opened) Click the last item on the interface to "check system compatibility" and then click "Automatically Check my system", so that the check results will be displayed later, report incompatible projects. If you want to install and use Windows XP, you must solve these incompatible projects so as not to stop them.

16. Retrieve pure dos for Windows XP

Sometimes we have to use some programs that work in pure DOS mode, but we cannot find pure dos in Windows XP. Do we have to give up these programs running in pure dos? Of course not! The following method enables you to enter the pure DOS mode in Windows XP.

Method 1: Use Win98

Before installing the XP operating system, start the system with the Windows 98 boot disk and use the Sys C: Command to transfer the system to the C drive. And copy the commonly used doscommands to the hard disk, and then install XP as usual. After the installation is successful, under the default menu "Microsoft Windows XP" of the Start Menu, a "Microsoft Windows" menu item is added. After selecting this menu item, because Windows 98 is not installed in the system, so now the computer will automatically go to the DOS system, and it is still in the real mode, so that we can achieve our goal.

Method 2: Use the start command

Enter start/seperate in the command interpreter of Windows XP to run the corresponding dos program. The separate parameter is used to start a 16-bit program in a separate memory space, while the shared parameter is used to start a 16-bit program in the shared memory space. After the DOS program runs, you can press Alt + enter to switch between the screen and window.

Method 3: Use tool software

We can also use a small tool pqvf.exe to download the software at 61.234.226.248/pqvf.exe. This software was used by some netizens to analyze related files of PQ magic and extract some file-making software, which allows Windows XP users to quickly guide to pure dos, after restarting, Windows XP can be started normally.

The pqvf.exe file is a self-extracting program. The names and functions of the extracted files are as follows: mbr.datand restrmbr.exe are mainly used to restore the Master Boot records of the hard disk, similar to executing the fdisk/MBR command, you can clear the primary boot sector without changing the partition table structure. Vfinst9x.exe is used to start the pure dos interface under Windows 9x, and vfinstnt.exe is used to start the pure dos interface under Windows XP. Pqvf. VFD contains a soft disk image file.

The specific method is to directly run the vfinstnt.exeand vfinstnt.exe files, which modify the Disk Master Boot Record, and then automatically restart Windows XP. After restarting, the drive letter you will see will be :. You can run the "Ver" command to view the current DOS version. The displayed version is "Windows 98 (version 4.10.2222)". It seems that it is pure dos! The necessary drivers such as himem.sys.emm386.exe, optical drive driver, and mouse driver are also installed, and a simple Chinese character system is automatically installed to handle common dos applications. If you want to return to the Windows XP interface, you only need to restart the computer.

Encrypt files in Windows XP
In Windows XP, files (folders) can be directly encrypted. However, this requires that the hard disk partition of the files (folders) to be encrypted is in nfts format. If your hard disk partition is not in nfts format, convert the operation and then encrypt it as follows.

Select the file (folder) to be encrypted, right-click the mouse key, and select the "attribute" option in the shortcut menu that will pop up later. In the "General" tab, press the "advanced" button to open the "Advanced properties" dialog box, select the "encrypted content to protect data" option, and click OK to exit.

Note: If the file (folder) is encrypted using the preceding method, it is recommended that you decrypt the file (the decryption method is similar to the encryption method) before re-installing the system, otherwise, the file (folder) may fail to be opened after the system is reinstalled.

Run the DOS program in Windows XP
Q: Recently I upgraded my system to Windows XP, but some of my old typographical software needs to run under DOS, while Windows XP does not have pure dos, how should I run the DOS program?

A: You can run the start command. Enter start/seperate in the Windows XP command prompt to run the DOS program. The separate parameter is used to start a 16-bit program in a separate memory space, while the shared parameter is used to start a 16-bit program in the shared memory space. After the DOS program runs, you can press "Alt + enter" to switch between the screen and window.
