I have a Lenovo ThinkCentre M71e running Windows 7 64bit. When I click on Devices and Printers Applet in the Start Menu, it tries to open but hangs. Eventually the hour glass disappears and nothing ever shows up in the Devices and Printers Applet. SOMETIMES after I reboot the computer the Applet shows the Devices and Printers but then reboot again, nothing appears in the Devices and Printers. Followed a bunch of suggetions like : Turn on Bluetooth Support in services, Run SFC /scannow, Run CHKDSK /r, none of these suggetions worked. I would hate to have to restore all 15 of these machines that we purchased from scratch. Please someone HELP!
