Someone in the UK posted a fix for this. I'm amazed that I can't find this fix anywhere else.

There is however a relative easy way to implement this missing functionality.You can create a desktop shortcut that points directly to the Bluetooth settings section of the Metro settings. Firstly hold down a finger on the desktop until the menu pops up, then select New-> Shortcut. Then paste the following in the destination box:
The part in bold should tie in directly with which language you selected when you set up your Windows 8.1 device. You can check the language by swiping charms->settings->keyboard, since most commonly you would have chosen a keyboard layout in line with the language settings on the device. Most likely it will be either UK or US, and if the shortcut you make with one doesnít work, try the other.Once you have made the shortcut, you can simply pin it to Start, and it will appear as a live tile that you can tap to take you to the settings page and turn BT on/off. Okay, itís still a two step process but thatís a heck of a lot quicker.
