4. Add EFS Options to the shortcut menu
The Encrypting File System (EFS) that Windows XP provides to help you perform cryptographic operations on files and folders that are 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 that is stored on an NTFS disk volume, the Encryption or decryption option appears on the shortcut menu that pops up later. Note that the Windows XP home Edition does not provide an EFS feature.
To add the EFS option to the shortcut menu, follow these steps: In the Run dialog box, enter regedit and expand the registry to the following subkeys: Hkey_local_ Machine\software\microsoft\windows\currentversion\exporer\advanced, on the Edit menu, point to New, and click DWORD Value. Enter EncryptionContextMenu as the variable name and assign the variable to 1. To ensure that you modify the registry, you should have an administrator account on your computer.

Windows XP provides remote Desktop functionality and is now proven to have design flaws that could lead to an attacker getting account information on the system's remote Desktop to help them further attack. When the connection is established, use Windows XP Remote Desktop to MINGWENFA the account name to the client connected to it. The account name that is sent is not necessarily the user account of the remote host, but the account name most often used by the client, and the sniffer program on the network may capture the account information.
Workaround: Download the appropriate patches to the Microsoft home page and temporarily stop using the Remote Desktop. Right-click My Computer, choose Properties, and in the pop-up window, select the "Remote" tab, tick off the "Allow users to connect to this computer remotely" check box before the hook, click "OK".

7. Resolve errors caused by DirectX
If you frequently receive DirectDraw error messages in your computer operations,
You can try to apply the DirectX Diagnostics tool to resolve the problem. "Attachments" → "System Tools" → "System Information" in the Start menu. In the displayed program interface, click the "Tools" → "DirectX Diagnostic Tool" (Figure 5) on the menu bar, and then switch to the "Show" tab in the pop-up window to view the DirectX feature item. Test the Dircetdraw and Direct3D on the current device, and disable this feature if you have problems.
8. Using the added disk tool
Many people are not comfortable with the familiar ScanDisk in XP, and it's strange that in fact, Windows XP already contains an enhanced disk tool: Check disk. So there is no need for ScanDisk. If you want to use check Disk: Open My Computer, right-click a drive, and choose Properties. On the Tools tab, under Check for errors, click "Check Now." If you want to check the partition from the command line, you can use CHKDSK c: such a format.
9. Forget to login password solution
XP Audit user security is very strict, if you forget to set the password, do not think you can choose "Cancel" like Windows98 to enter the system, it is believed that the installation of Windows XP Friend is very clear. Because there is no login password, unable to enter the system, many friends reluctantly chose to reinstall Windows XP, but this method is cumbersome and time-consuming and laborious, in fact, not so troublesome.
As you know, security management for user accounts in Windows 2000/XP uses the mechanism of the Security Accounts Manager Manager,sam, which is used by security Accounts Manager to manage account numbers through security IDs, The security identity is created at the same time as the account is created, and once the account is deleted, the security identity is also deleted. The security identity is unique, and even the same user name is completely different when the security identity is obtained at each creation time. Therefore, once an account has been deleted, its security identity no longer exists, that is, the use of the same user name to rebuild the account, will also be given a different security identity, will not retain the original permissions.
The specific performance of the security Account Manager is the%systemroot%\system32\config\sam file. The SAM file is a Windows NT/2000/XP user account database, and all user login names and passwords are stored in this file. Know these our solution also produces: Before the system starts, inserts the boot disk, enters the C:\WINNT\System3\Config\, uses the ren command to rename the Sam file, or uses the del command to delete the SAM file, restarts the computer. After renaming or deleting the Sam file, the trial administrator logs in, the password is empty, and succeeds.
10. Optimization of font installation
Some friends need to install a variety of different fonts, but some of the font itself is very large, especially Chinese fonts, generally around 10M, once installed too many fonts, will make the system disk bloated, in fact, from Win98 to WinXP, can be installed in the time to do a little optimization, The effect is to no longer copy the new font to the system disk.
Taking WinXP as an example, we set up a directory on a blank drive: newfonts (name, drive name arbitrary), and then put all the fonts that need to be installed in this directory, and then in the "start" → "run" inside the input fonts, open the font directory, and then open the "file →" Install a new font ", in the dialog box appears to find D:\NewFonts this directory, and then remove the" copy font to the Fonts folder "in front of" √ "(Figure 6), finally select the font to install, OK.
11. Voice Prompts Toggle key
In the process of doing a lot of English/Chinese character input,
It is often the case that the switch key is incorrectly pressed and the input is frequently faulted, resulting in a decrease in productivity (especially for fast blind typing). This problem can be effectively avoided if we set a sound prompt for the toggle key. In Control Panel, double-click the Accessibility Options icon, view the Keyboard tab in the pop-up dialog box, tick the Use Toggle key check box in the Toggle key item, and then click OK to make the setting rise (Figure 7).
12. Time Correction Automation
What if the clock in the Win XP system is suddenly not allowed? Believe that most people will use the manual way to recalibrate time; Unfortunately, no matter how careful we are, it is always impossible to achieve precise school by hand. To be precise about the clock, we can use the following methods to achieve:
Click the System clock icon in the tray area directly with the mouse, open the "Internet Time" tab page, select a standard Time server, click OK button, the system automatically connected to the Internet, and automatically compare the computer system clock with the designated server clock, If you find it inaccurate, you can adjust it automatically. However, if you want to adjust the accuracy, you must ensure that your system does not have a firewall installed.
13.XP can also disk scan
I don't know the number of Windows XP does not provide us with the ability to scan the disk, which has brought us some inconvenience to the disk collation. In order to solve this, after painstaking research finally found a solution.
In My Computer, right-click the partition for which you want to scan for detection, and open its Properties dialog box. Then switch to the Tools tab, click the "Start Check" button in the "error-checking" area, and select the "Automatically fix file system errors", "scan and attempt to recover bad sectors" option in the dialog box that opens (Figure 8), and then click "Start" button.
14. Prohibit the use of IE6 download files
Sometimes we need to prohibit IE download file function, but has been suffering from the lack of means to use the system settings, in fact, if a slight change in the registry can meet the requirements of everyone. Open Registry Editor to find HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3, Then on the right to find 1803 this DWORD value, double-click Modify to 3 can be. Restart IE to see if it can be downloaded? If you want to remove the limit, you only need to restore the DWORD value of 0.
15. Use of optical disc Detection system compatibility
Windows XP as the current personal installation of the latest operating system, on some classic machines often encounter the installation process is incompatible, so that the installation process in half forced to end. To avoid this, we can test the compatibility of the system with its installation CD before installing Windows XP.
The installation CD into the CD-ROM drive, generally will automatically open the Welcome interface (NOTE: If the CD-ROM automatically run, we can perform the SETUP.EXE command on the CD, you can also open) Click on the last item on the interface "Check System Compatibility" and then click "Automatically check my system", This will show the results of the check, report the incompatible items, to install the use of Windows XP will have to solve these incompatible items first, so as to avoid the halfway forced to stop.
16. Restore pure DOS to Windows XP
Sometimes we have to use some programs that work in pure DOS mode, but we can't find pure dos in Windows XP, do we have to give up the programs that run in pure dos? Of course not! Use the following methods to get you into pure DOS mode in Windows XP.
The first method: the use of Win98
Before we install the XP operating system, start the system with the Windows 98 boot disk and transfer the system to the C disk through the SYS c: command. and copy the commonly used DOS commands to the hard disk, and then install XP in the usual way, and when the installation is successful, a new Microsoft Windows menu item is added under Microsoft Windows XP in the Startup menu's default menu, and after this menu item is selected, Because the system does not have the WINDOWS98 system installed, so the computer will automatically go to the DOS system, but also the real mode, so as to achieve our goal.
The second method: using the Start command
In the Windows XP command interpreter, enter: Start/seperate to run the program, you can run the appropriate DOS program. The function of the parameter separate is to start the 16-bit program in a separate memory space, while using parameter sharing is to start the 16-bit program in the shared memory space. When the DOS program is running, we can also press the Alt+enter key to switch between the full screen and the window.
The Third Way: using tool software
We can also use a gadget pqvf.exe to achieve the goal, the software download address is 22.214.171.124/pqvf.exe. The software is a part of the user analysis of PQ Magic related documents, and extracted some of the files made software, you can let those Windows XP users quickly boot to pure DOS, reboot and normal use of Windows XP startup.
After downloading the Pqvf.exe file is a self-extracting program, the extracted file name and function as follows: MBR.dat and restrmbr.exe The primary role of these two files is to restore the master boot record of the hard drive, as does the execution of the FDISK/MBR command, You can clear the primary boot sector without changing the partition table structure. Vfinst9x.exe is used to start a pure DOS interface under Windows 9x, VfinstNT.exe to start a pure DOS interface under Windows XP. The pqvf.vfd contains a bootable floppy image file.
Run the Vfinstnt.exe,vfinstnt.exe file directly, they will modify the hard drive master boot record, and Windows XP will automatically reboot, and the letter you will see after the reboot is a:. Typing the ver command to view the current DOS version, which shows "Windows 4.10.2222", appears to be pure DOS! And such as Himem.sys.emm386.exe, CD-ROM drive and mouse driver such as the necessary driver is also installed, and also automatically installed a simple Chinese character system, can fully handle the general DOS applications. If you want to go back to the Windows XP interface, just restart your computer.
Encrypting files in Windows XP
It is true that you can encrypt files (folders) directly in Windows XP, but this requires a prerequisite: the hard disk partition in which the file (folder) You are encrypting is in nfts format. If your hard disk partition is not in nfts format, do the conversion, and then press the following method to encrypt it.
Select the file (folder) that you want to encrypt. Right-click the mouse button, and in the shortcut menu that pops up, select the Properties option, and in the General tab, press the Advanced button to open the Advanced Properties dialog box, select the "Encrypt content to protect data" option, and then make sure you exit.
In particular, we need to remind that if the file (folder) is encrypted with the above method, it is best to decrypt it (similar to decryption and encryption) before reinstalling the system, otherwise the system may cause the file (folder) not to open properly after reloading.
Running DOS programs in Windows XP
Q: Recently I upgraded the system to Windows XP, but some of my old typesetting software needs to run in DOS, and Windows XP has no pure DOS, how should I run the DOS program?
A: You can use the start command to run. At the Windows XP command prompt, enter: start/seperate The program you want to run, and run the appropriate DOS program. The function of the parameter separate is to start the 16-bit program in a separate memory space, while using parameter sharing is to start the 16-bit program in the shared memory space. When the DOS program is running, we can also press the "Alt+enter" key to switch between the full screen and the window.
