The ultimate fix was when MS Support advised be to go to services.msc and start Bluetooth services (and set it to automatic) -- I did, rebooted and the Windows 7 Pro Devices and Printers once again showed up!Not sure why Bluetooh services would cause my Device and Printers window to open blank (and seemingly keep looking for icons to populate the screen), but I am sure the code fix will be in a fuute windows update.There was no other place to put this so, I figured that this possible solution will help other early adopters of Win7

Thank you Rick. Your solution worked Cheers Mary

Great ! Thanks for sharing. I actually didn't have to reboot, but merely start the service. Unbelievable..... but it's working . Tkx.
