Bootcamp bluetooth mice not working in windows 7 pro

Question

I have an early 2008 MBP and just installed Windows 7. I cannot, for the life of me, get either of my bluetooth mice to connect in Windows 7. Both worked in XP and both work in Mac OS. The install is a clean one, not an upgrade. The mice are an older Logitech MX Revolution BT mouse and a Razer Orochi. During setup, they appear to connect, but don't. On second try, the bluetooth connection window just keeps spinning while connecting to the mouse (no system or app hangs, just no activity.) Any help would be greatly appreciated.

Thanks, alrich68.
Just before I checked your reply, I found a VERY similar post on MacRumors with a couple more steps and clarification on why the problem exists -

It took me two hours, but I fixed this last night.
First off, you need to go into Mac OS and remove the keyboard and mouse from your Bluetooth settings entirely. You'll add it back in later.
Boot into Windows.
Click on the Bluetooth control panel, and go to settings. Under Hardware, it probably says 'Generic Bluetooth Adapter'.
Click 'Properties' and 'Change Settings'.
Go to drivers, and 'Update Drivers'. Have Windows look on your machine to find all available drivers ('Let me pick from a list')
UNselect 'Show Compatible Drivers'.
Look for 'Apple' in the manufacturer names, then select the Apple Bluetooth Driver. Install.
Once this is done, pair your keyboard through the wizard. It should now bring up a passcode and confirm it much more quickly than before.
Once this is done, go back to Bluetooth settings and return the Drivers to 'Windows Generic'. If you leave it on the Apple drivers the keyboard will disconnect randomly and frequently.
Your keyboard will now be paired, but won't work. Go to the Device Manager, right click on the entry for the wireless keyboard.
Click on 'services'.
It should bring up a single entry for keyboard/mouse HID services. Click this and press Apply or OK. After it installs, you should be golden.
There are two issues here - one is that Mac OS seems to 'reserve' the Bluetooth device such that it won't pair correctly with any iteration of Windows while it's already paired in OSX. It works fine the other way around, however, so you need to make sure it's set up in Windows before Mac OS.
Second, there's a Bluetooth driver issue in Windows 7 such that it won't pair with the keyboard - it'll run through the steps, but the keyboard itself will not appear to actually 'get it'. Switching to the Apple drivers briefly will ameliorate this and allow proper pairing, but to actually keep the keyboard working you should use the built-in drivers.
Thanks again alrich68. Seeing the instruction worded in two slightly different manners, suddenly made sense. I now have the Mighty Mouse working as well! Work the first try!!
Chock another one up for the user base being more inventive and imaginative than the Apple engineers!!
I agree with other comments, that this solution SHOULD have been released as an official Apple Support post, and not having to rely on the user base to struggle with this problem to ultimately figure out a solution.
BTW - for those who may think apple actually reads these posts, they typically don't unless someone calls in on Apple Care and points out the problem and posts to the support tech. The forum is USER managed. So, unless someone actually calls Apple Care or sends an offical http://www.apple.com/feedback/ post, Apple does not know what happens here.
Anyway, thanks again!
