I've recently been experiencing problems with Bluetooth in Boot Camp and was wondering if some of you might have insight. In short, whenever I boot into Windows 7 (latest Boot Camp drivers), no Bluetooth peripherals work--most importantly, my Microsoft Bluetooth Notebook Mouse 5000. It won't discover or pair with any devices. Then when I reboot into OS X, I have to remove and re-discover/pair everything. But if I just restart OS X -> OS X, this isn't an issue. I'm running OS X Yosemite and Windows 7 SP1 on an mid-2013 Macbook Air. I already tried removing/reinstalling the devices in both Windows and OS X, to no avail. Enabling Bluetooth Collaboration in Windows didn't help either. I also tried resetting the SMC and PRAM. This all started happening after I took my MBA into the Genius Bar to get the screen replaced. I don't see why that'd have made a difference, but maybe it did.
