bootcamp and windows 8 Pro

Has anyone had a problem with the wireless Apple keyboard and mouse when using Bootcamp? I am running Windows 8 Pro. I have done a bootcamp software update after installing Mountain Lion on the OS X side and reinstalling Windows 8 Pro. My keyboard and mouse work fine on the OS X side and on the password page to Windows, but once on the desktop, NOTHING! Microsoft says they cannot help me at all and Apple has been very patient about trying to find a fix. All software is updated and all devices are working properly, according to the messages. I can hear "clicking" from the desktop speakers when trying to type using Word, so I would think that they keyboard is being recognized. I am NOT a super computer person, so I have no clue as to what the problem can be. I am just looking to see if anyone out there has seen this problem.
