In the process of using computers, we cannot avoid encountering many problems. And some problems are often encountered. If you learn how to solve them, you don’t have to worry about the problem every time. Here are some solutions to common problems. I hope it can help you.
- Common Problem
1 Retrieve mistakenly deleted data
Right-click the Start key and select Run. Type Regedit and press Enter. Expand HEKEY_LOCAL_MACHINE/software/Microsoft/Windows/CurrentVersion/Explorer/Desktop/namespace in turn. Right-click the right margin, and under the New list, select the Key.
Name this folder “645FFO40—5081—101B—9F08—00AA002F954E”. Right-click “Default”. Set its primary key value to “Recycle Bin”, and then exit the registry. Restart the computer and it’s completed.
As long as the computer has not been defragmented and the system is intact, the files can be retrieved at any time.
2. When Deleting a File, It Prompts that It Has Been Opened in Another Program
Right-click on the taskbar at the bottom of the window to start the task manager. Select performance. Click the “open resource monitor” below to open the CPU tab. Enter the name of the folder to be deleted in the search handle in the associated handle below. Then you can see below a process associated with the folder named Handle.
Because this program process is calling the folder, it causes the failure of deleting the folder. Then we right-click on the process. Choose to end the process. In the pop-up warning dialog box, click OK to end the process. Then you can delete the folder perfectly.
3. Cannot Close the Current Window
After the computer has been used for a long time, or the file currently being processed is too large, the system will suddenly freeze and the window cannot be closed. In addition to restarting the computer, there is a way to quickly close the current window.
Move the mouse to an invisible place in the lower right corner of the computer and click once to return to the desktop. Then find the software that is stuck just now on the taskbar, right-click, and select close window. Wait a few more seconds and it will be ok.
4. The Numeric Keyboard on the Right Side of the Keyboard Cannot Be Used
When using the keyboard, you may encounter such a problem: the numeric keyboard on the right side of the keyboard cannot be used, and the “NumLock” light is on.
Solution: If you are using Windows 2000/XP, it may be because the mouse button function is activated, and the small numeric keyboard is used to control the mouse pointer, and the input function is lost.
The method to turn on the number keys is: press the shift key 5 times or directly press Shift+Ctrl+Alt, and select “Settings” on the “Sticky Keys” window that pops up. Select the mouse tab in the pop-up “Accessibility Options”. Then remove the check mark in front of “Use mouse button”. Then click “Apply”—”OK” in turn.
If you want to use the numbers on the keypad as a mouse, the method is just the opposite. Just check the “Use mouse to build”. At this time, “8” represents the upward movement button. “2” represents the downward movement button. “5” represents the enter button, and so on.
5. The Computer Cannot Search for WIFI
The first method: Right-click the WIFI icon on the taskbar to open the Network and Sharing Center. Click the “change the adapter settings”. Right-click the wireless network. Disable it and then open it.
The second method: open the network connection in the desktop. Open the Network and Sharing Center. Click Troubleshoot problems. Click on the network adapter. Click Next. Wait patiently for a while, you will find that WIFI appears.
The third method: This method is suitable for the WIFI icon disappeared on the taskbar. First, right-click the taskbar at the bottom of the computer and select ” Settings”. Then on the page that pops up, pull down and click “Turn system icons on or off”. Find “Network” at the page. Click the switch at the back, and set it to “On”. Now, the WIFI icon will reappear in the taskbar in the lower right corner of the computer.
- Problems That Safe Mode Can Solve
1. Check and Kill the Virus
Start the computer. Before the system enters the Windows startup screen, press the F8 key (or press and hold the Ctrl key when starting the computer), and the operating system multi-mode startup menu will appear. Just select “Safe Mode” to start the computer Boot into safe mode.
When deleting those virus files or clearing the contents of the resource recycle bin under Windows, the system sometimes prompts “the file is in use and cannot be deleted”. After entering the safe mode, Windows will automatically release the control rights of these files. Delete them.
2. Detect Incompatible Hardware
The XP system adopts the digital signature driver mode, and the detection of various hardware is stricter than before. Therefore, some devices may not be driven and used under normal conditions. If you find that XP cannot recognize the hardware in normal mode, you can press F8 during startup, and then choose to enter safe mode. Detect new hardware in safe mode.
3. Repair System Failure
When our system is unstable or in malfunction, don’t rush to reinstall the system. We can try to restart the computer and switch to safe mode to start. Then restart the computer.
If it is caused by a problem with the registry System failure, the system will quickly return to normal, because Windows can automatically repair registry problems when starting in safe mode. After successfully starting Windows in safe mode, you can generally start in normal mode (Normal).
4. Restore System Settings
If users install new software or changes some settings, the system cannot start normally. It also needs to enter the safe mode to solve it. If it is caused by the installation of new software, please uninstall the software in the safe mode.
If some settings are changed, it causes a black screen. For example, the display resolution setting exceeds the display range of the monitor. Then you can change it back after entering the safe mode.
Also put the screen saver with a password in the “Startup” menu. After forgetting the password, the computer cannot be operated normally. You can also enter the safe mode to change.
