Devices and Printers not show up in Windows 8 - Windows 8

Hi all,

I don't know why when I click on Devices and Printers in Control Panel, it always loading so I just click on it again and after I get into it, nothing shows up at all. I don't know what should i do to fix this problem...

Any suggestion would be appreciated.

I have the same problem; after clicking on "add devices and printers" I get the "choose a device or printer to add to this PC" window that says "searching for devices" endlessly without timing out.
