Double-click can't open the folder. Q: There is something wrong with my computer. I can't open this folder in the resource browser or my computer. Double-click the mouse to enter the search interface instead of opening the folder. Why? A: You can modify the registry to restore it. Go to HKEY _ Class _ Root \ Directory \ Shell in the registry and delete the lookup. Another method is to click "New" in the "Advanced" option of the folder, enter "OpenNew" in the "Operation", and then enter "Explorer% 1" in the "Application of Operation". If you delete find, you don't need to configure it. If you create a new Opennew, you need to set "OpenNew" as the default value.

2. Solve the problem of multi-system installation

For multi-system installation, first set the system startup sequence as "CD first startup" in BIOS, and then put the Win98 installation CD into the CD-ROM drive to start the computer for installation. Select "Other Directory" in the "Select Installation Directory of Windows98" window, specify "E:\WINDOWS", and then complete the installation as usual. Restore the multi-system startup menu When you restart the computer after installing Win98, do you find that the familiar multi-system startup menu does not appear, which makes Win2000 and WinXP unable to start? What should I do? Don't worry, we will restore the multi-system startup menu step by step. ① First, set the system startup sequence as "CD priority startup" in BIOS, and then put the Win2000 installation CD into the CD-ROM drive to enter the installation screen. At this time, there are three options to choose from. Press "R" to enter the maintenance project. There are two options in Windows2000 repair options. Press the "R" key again and select "Repair Windows 2000 through emergency repair process". Two options, Manual Repair and Quick Repair, appear, and select "Manual Repair". ③ Next, enter the "Select Repair Task" window, click the "[X] verify Windows2000 system files" option, and then click "Continue (perform the selected task)" to start repairing the boot sector. ④ At this time, the Windows2000 installation and repair program will ask you if you have an emergency repair floppy disk. Because we don't need to repair the floppy disk, press the "L" key to let the installer automatically find out why Windows2000 can't start. The Windows2000 repair program finds the Windows2000 that needs to be restored, and presses Enter to restore it. At this time, the repair program will automatically check the disk and boot sector, and then set the startup menu. This will not only retrieve Win2000 that can't be started, but also automatically add Win98 to the startup menu. ⑤ Although there are Win2000 and Win98 in the startup menu, WinXP has not recovered, so don't worry! Enter Windows2000, put the WindowsXP installation CD into the CD-ROM drive, and then enter the i386 directory of the CD-ROM drive. You can find ntldr and Ntdetect.com files and copy them to C:\. At this time, the multi-system menu will be restored, and WinXP can also enter. But you will find that the multi-system startup menu has actually become English. At this time, we can open a Boot.ini file in the root directory of C: disk and edit the content.

3. Solve the problem of system shutdown and restart.

System shutdown and restart failed 1. Setting BIOS correctly If your computer is connected to a network or USB device, incorrect BIOS setting may cause abnormal shutdown. Generally speaking, old motherboards are prone to this kind of failure, so you can disable the network wake-up and USB wake-up options in the BIOS. Second, setting power management shutdown is closely related to power management, and sometimes incorrect power management options can also lead to shutdown failure. Click "Start → Settings → Control Panel → Power Options", and in the bomb window, enable or cancel "Advanced Power Support" as needed (if "Advanced Power Support" is enabled in case of failure, try to cancel it, otherwise enable it). This method in Windows98 can often solve most shutdown failures caused by power management. If "Turn off the power when pressing the computer power button (E)" in the "Advanced" menu is not selected, just select it. Third, disable fast shutdown. Sometimes using the quick shutdown function of Windows can also lead to this shutdown failure. In Windows98, it can be solved by the following methods: enter Msconfig in Start → Run, open the system configuration utility, select Disable Fast Shutdown in the advanced options, and then restart the computer.

4. Solve the problem that the optical drive can't read normally.

Q: My computer has WindowsXP operating system installed. One problem after installation is that you can't read the CD continuously. When I inserted the first CD, everything was fine. When I opened the CD-ROM drive and put in the second CD, I found that the contents were actually the contents of the first CD. After restarting the machine, the second CD can also be read normally. What is the reason? Answer: Right-click "My Computer", select "Manage", select "Storage → Removable Storage → Library", click the letter where the CD is located, right-click "Properties" in the name item, and there is an item called "Recovering Unmountable Media" under "Delayed Unloading". Changing the time to 0 should solve this problem. If the problem cannot be solved, please open the registry editor and find HKEY _ local _ machine \ system \ current control set \ control \ {4d36e965-E325-1ce-bfc1-08002be/kloc-.

5. Solve the problem that the recycle bin cannot be emptied.

The recycle bin cannot be emptied. Q: My system is WindowsXP. After I deleted a file named "dvdregionfree303 1" from disk C, the system had a problem, and it showed that the contents in the recycle bin could not be emptied. Every time I opened the recycle bin, I always searched first, and then a dialog box to confirm the deletion was displayed when the recycle bin was emptied. When you select Yes, it is cleared. This happened when the recycle bin was opened again. Ask me. Answer: use the command line to boot into the safe mode, then execute the Attrib-s-r-h command on the recycling directory under each partition to delete special attributes, and then use the Del command to delete the recycling directory under each partition. After the operation, restart to enter the normal mode, and the problem can generally be solved.

6. Solve the problem of intermittent response.

The operating system stopped responding to the letter from Hainan reader Li Jun: I used Win98 and WinXP dual operating systems. WinXP is used most of the time. Always stop at "Save System Settings" when shutting down or restarting, and the light on the hard disk will no longer flash, so the system will not respond! What is the reason? A: When turning on and off, the system always prompts: "Saving system settings". This is mainly because there are too many files loaded after the system runs, which leads to too many files running in a short time and can't be stopped. We can use "Ctrl+Alt+Del" to call up the Windows Task Manager, and click "Process" to view the currently running files. To solve this problem, type "Msconfig" command in "Start → Run" and click the "Start" tab in the "System Configuration Utility" dialog box displayed by bomb. Here are some programs starting from the system, just remove the hooks in front of some uncommon programs. In addition, too many hard disk fragments can also cause the system to shut down or restart, and even lead to a crash, so we should scan the hard disk fragments regularly. This problem can also occur if you set a sound file when you shut down or log off, and if the sound file is damaged. We can remove the sound in Control Panel → Sound and Audio Settings. If the problem is still not solved, we can right-click My Computer, select Manage, select Services in Services and Applications, and disable unnecessary services in the window on the right. Please read the text description of the current service carefully before stopping.

7. Solve the slow response of the start menu.

The response speed of the start menu is too slow. Q: Every time I click on the start menu of Windows, the next set of menus is very slow, but when I clicked on the start menu before, it was very fast. I want to ask how to adjust the bomb output speed of the start menu. Answer: the bomb output speed of the start menu can be controlled. We can modify it in the control panel: open the Registry Editor, expand HKEY _ Current _ User \ Control Panel \ Desktop branch in turn, and then create a DWORD value here, named "Menushowdelay". You can set the key value of this key to a value between 0 and 0 100000.

8. Solve the problem that the taskbar icon becomes larger.

The icon on the taskbar is getting bigger. Q: I don't know what I've done recently. The icon on the taskbar has become as big as the desktop. Although it does not affect the use, it looks unsightly. How can we restore the original state? Answer: Run regedit.exe to open the Registry Editor, find HKEY _ Current _ User \ Control Panel \ Desktop \ Window Metrics, and find the string value "Shell Icon" in the right window. You can change the size of the icon by changing its value. Generally, it is the value of "32". Please back up the registry before modifying it.

9. Solve the problem that the right mouse button is locked

Solve the problem that the right mouse button is locked Q: My computer doesn't know why the right mouse button is locked and can't be used. How to solve it? A: Someone may have tampered with your registry and locked the right-click menu. Open the Registry Editor and select the following subitem: "HKEY _ Current _ User \ Software \ Microsoft \ Windows \ Current Version \ Policy \ Resource Manager" Find the item named "NoViewContexMenu" in the right pane and change its data to 0000000. Or simply delete this key value.

10. Solve the power-on problem when plugging in.

Phenomenon: Some friends have the habit of disconnecting the power supply of the power board after getting off the plane, but they are often troubled by a problem, that is, as soon as the power board is powered on, the computer will automatically turn on, and the power button is useless. Solution: Some motherboards have an option "PwronAfterPW-Fail" in the "PowerManagementSetup" of BIOS settings, and its default setting is "on", so it will not be automatically turned on the next boot. Without this option, you can turn off the ACPI function in power management and then turn it on again. If it is closed, just open it. Most motherboards have an option in BIOS: that is, in POWERMANAGEMENTSETUP, you can choose the state of the machine when it is called again after an unexpected power failure, whether it is automatically turned on or kept off or kept in the state before the power failure. Please set auto-start to off. In addition, poor quality of power supply or motherboard may also lead to similar problems. The startup of ATX motherboard needs to detect the level signal of a capacitor. If the power supply is not connected well at one time, it will produce instantaneous surge current, which may make the power supply mistake for a start signal, thus leading to wrong start.

1 1 explorer

The role of Explorer.exe program in the system Every Windows operating system will start a process called Explorer.exe at runtime. This process is mainly responsible for displaying icons and taskbar on the system desktop, which has different magical functions in different systems. The application in Windows9x is in Windows9x, and this process is needed when running the system. If you end the Explorer.exe process by "End Task", the system will refresh the desktop and update the registry. Therefore, we can also use this method to update the registry quickly. The method is as follows: Press Ctrl+Alt+Del to display the End Task dialog box. Select the Explorer option in this dialog box, and then click the End Task button to open the Close Window dialog box. Click the "No" button, and another dialog box will appear later, telling you that the program has not responded and asking whether to end the task. Click the "End Task" button to update the registry and return to the Windows9x system environment. This is much more convenient than the tedious restart process? The application of Windows2000/XP in WindowsNT kernel system, such as Windows2000/XP, does not need Explorer.exe process when the system is running, and can be finished through the task manager without affecting the normal work of the system. Open the program you need to run, such as Notepad. Then right-click the taskbar, select Task Manager, select the Processes tab, select Explorer.exe Process in the window, and then click the End Process button. Next, except the wallpaper (except the wallpaper of ActiveDesktop), all the icons and taskbar on the desktop disappeared. At this time, you can still operate all the software as usual. I want to run other software, but there is nothing on the desktop at this time. Don't worry, there are two ways to skillfully open other software: the first method: press Ctrl+Alt+Del to open the Windows security dialog box, click the Task Manager button (or press Ctrl+Shift+Esc directly), select the application tab in the Task Manager window, click New Task, and click Create in the Bomb window. You can also select "File → Open" on the running software. In the open dialog box, click the "file type" drop-down list, select "All files", then browse to the software you want to open, right-click and select the "Open" command in the shortcut menu to start the required software. Note that you cannot open the software by clicking the "Open" button at this time. This method is suitable for most software except Office series. By ending the Explorer.exe process, the memory used by the system can be reduced by about 4520KB, which will undoubtedly speed up the operation of the system and free up valuable space for users with tight resources. Tip: After restarting the Explorer.exe process, some software will send a message on the small icon in the system tray of the taskbar, but the software will still run normally. If you feel a little inconvenient, you can open the software again to display small icons.

12.folder.htt and other files.

Problems with files such as folder.htt Q 12.2: Recently, two files, esktop.ini and folder.htt, have appeared in all folders of my computer and cannot be deleted. Some people say it is a virus. Just format the system and other partitions. But all my things are useful and can't be formatted. What should I do? Your computer may be infected with VBS virus. KJ script virus. The virus is written in VBScript language, spread by mail on the Internet, and can also be infected by files. After infection, the machine system consumes a lot of resources and is slow; Use the "resource manager" of Windows system for parasitism and infection. Generate desktop.ini and folder.htt files (hidden properties) under each selected folder. Moreover, the virus will modify many key values of the registry. Manual deletion is difficult. It is recommended to use antivirus software to avoid formatting your hard disk and protect your data. Jinshan Company's anti-virus emergency treatment center's "New Happy Hour" killing tool works well and provides free download. The download link is only 56KB in size in ftp://www.iduba.net/download/othertools/scanvbskj.exe..

Problems with folder 13.found.000

Question about the found.000 folder Q: My computer sometimes has a folder named found.000 under the root of drive C or drive D, which contains some files with the suffix CHK. C: \ There are many strange files starting with fff under c:\windows, all of which are 0 bytes in size. Excuse me, what are these documents? Can you delete them? A: Some files with the suffix CHK in the found.000 folder are "lost cluster recovery files" generated after you use the disk defragmenter to clean your hard disk. Under c:\windows, many files starting with fff are generated by the program Mdm.exe(MachineDebugManager). Mdm.exe's main job is debugging application software. During debugging, some temporary files will be generated, which will not be automatically cleared when the operating system is shut down. Therefore, these strange files with the beginning of fff and some files with the suffix CHK in the found.000 folder are useless LJ files, which can be deleted at will and will not adversely affect the system. However, as long as Mdm.exe exists in the system, strange files starting with fff may be generated again. You can stop the system from running Mdm.exe to completely delete unfamiliar files starting with fff by pressing Ctrl+Alt+Del, selecting Mdm in the closing program window displayed by the bomb, pressing the end task button to stop Mdm.exe's operation in the background, and then renaming MDM. Exe (in the C:\Windows\System directory) to MDM. Run the msconfig program and deselect "MachineDebugManager" in the startup page. In this way, you can prevent Mdm.exe from starting by himself, and then click OK to end the msconfig program and restart the computer. Besides, if IE5 is used. X. It is suggested to disable script calling (click "Tools → Internet Options → Advanced → Disable script calling") to avoid the strange files starting with fff from appearing again.

14. That is, maximize the display.

Let IE display at maximum. Q: I use Windows2000 as the operating system. After surfing the Internet for a period of time, I suddenly found that IE could not be displayed at the maximum.
