1. Open a folder at will. There is a "organize" button in the upper left corner. Select "Folders and Search Options" in it, and select "Open each folder in the same window" in the pop-up window as the first item on the General tab.

2. Maybe the problem of IE has affected here. If it is useless to select the same window in the folder, reinstall IE. Note that it should be 64 bits. If you start to fashion 32 bits, it will still happen, so you must change it to 64 bits.

3. Because explorer of WIN7 contains IE, a dynamic link file, which is available in both x86IE and 64-bit ieproxy.dll under WIN7 X64 system. If 32-bit ieproxy.dll is used in a 64-bit system, this problem will occur in the system, and 32-bit IE cannot be opened.

The solution is:

Run the command prompt as an administrator and copy the following command:

regsvr 32“% SystemRoot % \ System32 \ actxprxy . dll”

regsvr 32“% program files(x86)% \ Internet Explorer \ ie proxy . dll”
