I had several problems that the doubleclick function to open, explorer, Find has no longer functioning. What I do, I do some modification on registry and found that all the menu command has been directed to “openfiles.exe” under c”\windows\system32\. I managed to modify it and all the folder, drive including My Computer, My Documents, Network Drive etc has to open via explorer. But there’s custom toolbar contains folder that I can’t open. My question is how reset back to normal.
