I've got into a right pickle trying to get my Bluetooth Magic Mouse working with my bootcamped iMac. It works fine on macOS, but in Windows it currently isn't scrolling, right clicking and periodically won't connect on start up and I'll have to go into macOS, disconnect and reconnect to get it working.
System Software Overview (from macOS):
System Version: macOS 10.13.3 (17D47) Kernel Version: Darwin 17.4.0
System Info (From Windows 10)
OS Name Microsoft Windows 10 Home Version 10.0.17134 Build 17134 Other OS Description Not Available OS Manufacturer Microsoft Corporation System Manufacturer Apple Inc. System Model iMac16,2 System Type x64-based PC
Things tried (and how we got here)
It started off with just the not connecting at all when booting into Windows, in spite of everything I tried from the Windows side. Trying to connect to the mouse through Bluetooth repeatedly failed, and turning the mouse off, on, clicking, etc, all the normal things which might fix this normally, didn't.
What follows is the edited highlihts of my attempts to fix this, with much flailing, swearing, restarting, swearing some more and storming off omitted. This is not a comprehensive list.
Reading at this stage included:
Apple Magic Mouse is discoverable, but not pairing (doesn't seem to apply here, even though I tried this)
https://discussions.apple.com/thread/7151690 (my version of Windows isn't even listed here and the download link is quite old). Before posting this, I decided to try this link, and am told using the newest version that "This version of Boot Camp is not intended for this computer model.".
https://discussions.apple.com/thread/8175827 (from this, I unchecked allow this computer to turn off the device. Helped, but didn't fix entirely)

https://discussions.apple.com/thread/7439976 (temporarily solved the issue each time for a few restarts)
https://discussions.apple.com/thread/8125747 (tried resetting the SMC and the NVRAM to see if it helped, I'm not sure it did).
After all this, I carried on searching, unhappy with still needing to boot into 2 OSs every time I wanted to use Windows with a mouse. I came across this blog post online: https://forums.macrumors.com/threads/bootcamp-windows-7-magic-mouse-wont-work.1519990/. As a result, I booted into macOS, unpaired my Magic Mouse, booted back into Windows and paired it from there. And it worked! All was well in the world for a few weeks.
However, I then came to my computer one day and the mouse wasn't responding again, again in spite of all the usual tricks. Getting desperate, I looked around and read somewhere (sorry the link eludes me) that uninstalling the driver and restarting would cause it to reinstall and could fix some common ailments. So I tried it. Restarted, and the mouse was still not working. I then decided to unpair and try re-pairing with the computer. However, when I tried this, I kept receiving an error saying that the Bluetooth device cannot authenticate (cannot remember the exact phraseology). I tried for days but couldn't resolve this, so eventually I resorted to booting into macOS, disconnecting and reconnecting the mouse, then booting into Windows, and voila, I can at least move and left click the mouse again.
however, now I can't scroll or right click the mouse, which is a royal pain!
Anyone know how I can my mouse properly working between Windows 10 and macOS? Do I have to just buy a separate mouse? Nuke my Windows partition and start again? Or is there a way of having this pair work nicely?
Any help really, really appreciated. This has been a pain for months.
