I have Win7 RC1 running on three boxes -- one desktop and two identical Dell Latitude D830 laptops. The 32-bit RC1 laptop and the 64-bit RC1 desktop open Devices and Printers without issue. One laptop runs 64-bit RC1. On that one, Devices and Printers takes forever to run the green bar across, and eventually stalls. I can't modify or delete a device, although I can install a new one. The only difference I can tell between this box and the others is a connection to a networked printer. However, I can't delete that printer definition, since I can't get past the Devices and Printers stalling issue. Any assistance is much appreciated.
