Win7 the U disk can not safely exit how to solve?

U disk in peacetime office and daily life are frequently used, in the use of U disk, we will click on the lower right corner of the computer "safe removal of hardware and pop-up media", in addition to safe exit, will inevitably encounter "now can not stop the universal Volume Device" pop-up window, that the U disk can not exit, this case, Can not be hard to pull every time oh! Because the data in the U disk can be lost, damage does not say, the computer will also sooner or later crash!

The following small series is taken in the WIN7 system encountered this situation, part of the reason for analysis, and to provide solutions:

1, the reason: in the use of U disk in the process, the file or data extraction, the use of the "copy, paste" method, resulting in copying to the computer on the U disk file has been stored in the system's Clipboard.

Workaround: Empty the Clipboard, or select a file on the computer to copy and paste the operation on it.

2, reasons: U disk in some files have a virus or other similar trojan, firewall or antivirus software on the related file processing, so that the system can not disconnect data with u disk, causing u disk can not exit.

Solution: (in ensuring that all of the more obvious with the U disk-related program has been closed) firewall and anti-virus software, and then the U disk safe exit.

3, if the above 2 kinds of methods can not solve the problem, you can press the CTRL + Shift + ESC key combination on your keyboard, open Windows Task Manager, select the Processes tab, and find the process named "Rundll32.exe" under the Image Name column. Select the process and click End Process. (Because the Small series U disk now does not appear the U disk can not exit the problem, so there is no "rundll32.exe" process, therefore, to end the "qq.exe*32" process as an example) as shown in Figure 1:

(Figure 1)

Then task Manager will pop up the warning, ask if you want to close this process, click "End Process", you can safely exit the U disk. As shown in Figure 2:

(Figure 2)

4, click "Start", and then select the shutdown side of the Drop-down button, select "Logout", and other systems to log in again after the U disk security exit.

5, if the above several methods can not solve the U disk exit problem, directly shut down the computer, to shutdown after the U disk can be pulled out.

PS: For your lovely u disk life security, in the U disk read and write data, you must not pull u disk, otherwise it is not internal injury is death!
