tyliang, First try this:
Click Start>Run then copy & paste or type in:
regsvr32 /i shell32
Note that the spacing is important.
Restart your computer.
If that doesn't correct the problem it could be a context menu handler problem. Follow the instructions under "Method 2 - Using ShellExView to determine the Context-menu causing the problem" at the link below.
Right-click is slow or weird behavior caused by context menu handlers
I open start menu and then all programs. When I right click a folder in all programs and select either explore or open, it will open the Move To and Copy To option. I have press cancel before I could proceed to the proper windows. Is this ContextMenuHandler bug or infected with some malware?
