Recently purchased my first Mac, the 21.5" iMac, and have found it a great experience so far. Though I dabble with Mac OS I primarily use Windows 7 Ultimate 64-bit, which I installed off the retail disc. Things worked great until I let Windows update and install Service Pack 1. Big mistake, apparently! Now no Bluetooth devices work. The icon has disappeared from the bottom-right taskbar. It is not "hidden." Attempts to force the icon to appear inform me the process is not running but will happily show next time it does. My first attempt to fix was to reinstall the bootcamp drivers from the OSX disc. No dice. Then I attempted to fully reset the iMac by pulling the power cord. No help there either. I also updated Boot Camp to 3.3 from 3.2 (I'm running Leopard for no reason I understand, as it says Lion on the box), but this too didn't help. Exhausted with the time wasted and no help to be found on the world wide web, I decided to just restore Windows to before I installed SP1. This didn't result in an error, or a critical error, but a catastrophic error (or so the error message said) and could not even start the restoration. Bluetooth still works fine when I boot into OSX, and as far as I know other drivers for Internet and video still work fine in Windows. I've poured over the net for most of the day, and I'm just at a loss of what to do next. I can manage to use Windows with a pen tablet, but I have no USB mouse or keyboard, so you can see the problem I have. Any help would be greatly appreciated. Thanks.
