I too am having this problem. I've been avoiding it for many months. I felt compelled to let you know that I don't have any HP products, yet I still get the problem. Thus, it's less likely an HP bug, and more likely MS bug. I tried just about everything on this thread with pretty much the same results. Occasionally, Devices and Printers loads normally, but most of the time it takes about 3 or 4 minutes to load. I use all Canon printers, with the exception of a Dell Laser Color Printer (wifi). All of which work at the moment. I did have a bunch of scanner problems, but those went away at some point (I think I updated the drivers If i recall). Anyway, I hope someone figures this out. it's pretty much my only complaint about windows 10.
