Solve XP's inability to stop the 'general volume' method collection

        The first method: A very small and practical software abroad, only 191KB, called unlocker, very easy to use! This software can unlock USB connected devices! It is 100% safe to remove the USB connection! The second method: We only need to turn off the preview function of the system, this problem will not appear again, the operation method is: double-click My Computer - Tools - Folder Options - General - Task - use Windows traditional style Folder, then click Apply - OK. It's ok! The third method: Close the open file that exists on the mobile device. Do other operations on the hard disk partition, such as "copy", "paste", etc., and then stop. End the "rundll32.exe" process, you can also delete it normally. Method: Press the "Ctrl" + "Alt" + "Del" key combination at the same time, then the "Task Manager" window will appear, click the "Process" tab, and look for "rundll32" in "Image Name". Exe "process (if there are multiple "rundll32.exe" processes, all can be closed.), select the "rundll32.exe" process, and then click "end process", then the "task manager warning" will pop up, then In order for the user to determine whether to close the process, click "Yes" to close the "rundll32.exe" process. There is also a last resort, turn off the computer, and wait until the flash drive's indicator light is off, then you can safely pull it out; if there is no flash memory, then the computer power indicator will turn off and then safely. However, the above methods all occur after the "cannot stop the universal volume device, please wait for the device later" problem, then is there any way to prevent this problem? First insert the flash memory into the USB interface, then use the right mouse button in Windows XP Click the "My Computer" icon, expand "Properties → Hardware → Device Manager → Disk Drive", find "USB Flash Drive USB Device" (the flash name of different brands may be different), and then double-click it to open "USB Flash Drive" USB Device Properties dialog. Switch to the "Policy" tab, select "Optimize for quick delete", click "OK" to exit. In the future, ignore the “Safely Remove Hardware” icon in the system tray. As long as the data is not read or written to the flash memory (ie, the flashing light does not flash), you can directly remove the flash memory from the USB interface. The fourth method: Uninstall the entire USB driver, reinstall the fifth method: In the "Start" ---- "Run" type this command: REGSVR32 /U SHMEDIA.DLL
