With Bluetooth - yep, I came across the same thing. I've been fiddling with Windows 8 quite a bit to make it like Windows 7 (there are aspects I like of the OS), but I uninstalled a bit too much. Most people probably won't have to do this, but what I did was use "sfc /scannow" in the command prompt (elevated) in Windows 8 desktop mod. Rebooted back into Windows 8 shell and Bluetooth was working fine. That bit of info is for anyone who removes too much and stuffs up Windows 8. Then I switched shells back to Windows 7. Now in Windows 7 mode, the send/receive file dialogs work fine, but the Show Devices doesn't (thereby making it next to impossible to add a device such as speakers or headsets and so on). I think the reason for this is because that part of the OS uses the PC Settings screen, which is Metro. How I got around it is booting into Windows 8 desktop and add the Bluetooth devices in there, then back into Windows 7 mode. Personally it shows how much of a half baked attempt (no offense to the MS developers out there mind you) Windows 8 is for the desktop user. But really loving this app, love starting Windows and having no Metro stuff! Oddly enough I liked the Metro/Tiles at first, but after a while it just got really frustrating!
