Win7 Explorer (folder) always open in new window

        Today, the computer suddenly has a problem. I installed Clover as a resource manager. Double-clicking on any folder does not respond and cannot be opened. But right click on the folder, then select Open to open the folder successfully, I don't know what happened. At first I thought it was a problem with Clover. Well, I uninstalled the original resource manager directly. But found a more serious problem, double-clicking on any folder will open from a new window. Checked a variety of information on the Internet, the folder options in the tool configuration is absolutely correct, but the problem has always existed, restarted several times, the computer is still faulty. I want to focus on the system, but it is too hard. . . Also read some online information, saying that it may be a problem with IE browser. Just saw the Java directory inside the Program Files in my C drive actually has an Internet Exporler folder. This is imaginable. . . It may be that I accidentally dragged this IE folder into the Java installation directory and then it caused a series of problems. Well, cut this folder directly into Program Files, double click on any folder, OK, the problem is solved. The problem of tangling for a long time is solved. . . If you have a similar problem, then check if the IE installation directory of your C drive is still healthy. If you are not there, you can download an IE to install it online, and see the information to solve the problem.
