trackpad work. You need to install trackpad++
(http://www.techspot.com/downloads/4967-trackpad-control-module.html), it will enable the trackpad driver on boot camp. After you install the trackpad++, trackpad++ will complain something. ingnore it. You should be able to enable trackpad. And you can now even uninstall the trackpad++, the trackpad will sill work.
Also,
went into Device Manager and on the two "Touchpad" entries with the bang on them, went to "Update Driver" -> "Browse My Computer" -> "Let me pick from a list..." and changed them both to USB Input Device. Reboot.
Go back to Device Manager, do an "Update Driver" again, let it search automatically, and one comes back as Apple Multitouch and the other as Apple Multitouch Mouse. Rebooted again, trackpad working and shows up in Boot Camp control panel.
brightness, what graphics card are you using? It might be due to the auto adjusting brightness running there. You can go to your power options, edit the one you are using (Change plan settings >> Change advanced power settings) and look for Batteries >> Enable adaptive brightness and disable the one you are using. After that, the scrollbar for adjusting brightness in power options should work again.
HDMI audio in Windows 7 64 bit
reinstalled the Intel video drivers and audio worked immediately.
My config: 2011 Mac Mini 2.3, Intel 3000HD video
. . upgrade to 8GB ram
Samsung 8000 series LED TV connected with HDMI
Memorex external BluRay writer(USB only power)
After partitioning drive with boot camp and reboot, install Windows 7 with install wizard.
When asked whether to allow automatic updates say 'no', then complete installation and run boot camp tools for Windows.
Because the network driver gets installed prior to the Intel video driver, Windows will install the Windows Update Intel video driver which breaks HDMI audio.
When auto updates are off, the Intel video driver that is correct gets installed last. HDMI audio works with this driver.
Apple should install the Intel video driver first and it would solve this problem.
I now have full blown 3D BluRay support on the MacMini with TruHD audio, fantastic!

bluetooth connection is incredibly unreliable/intermittent when in Windows (I run Windows 7 64-bit and Boot Camp 4.0, and got both devices connected without any trouble via Bluetooth).

After much testing, I have found the cause of lagging/jumpiness on the Bluetooth Magic Mouse and Magic TrackPad in Boot Camp. Hopefully this will help others:
The drivers for the Broadcom 802.11n Wireless Adapter have a setting called "Bluetooth Collaboration" that is Disabled by default. Enabling this option removes the problem instantly. My Magic Trackpad now works flawlessly, even if I stand 6 metres from the machine. It now works just as well as under Mac OS. The setting can be found under:
Control Panel > Device Manager > Network Adapters > Broadcom 802.11n Network Adapter (right click and choose "Properties".
Under the "Advanced" tab, highlight the setting named "Bluetooth Collaboration", then change it to Enable. Then click OK.
I narrowed the problem down to the wireless card by disabling ALL startup services and processes for Windows, then re-enabling one by one.
As soon as I enabled the Windows Wireless Service, the problem came back.
Similarly, disabling the Wireless Card inside the Network and Sharing Center (or Device Manager) removes the problem.
This led me to believe it must be a driver issue with the wireless card, since the problem didn't occur with the Magic TrackPad under Mac OS, or on my mother's Windows 7 64-bit computer.
So when I went into the Driver Properties to check for an update, I found this setting about Bluetooth Collaboration.
All Apple notebooks use the Broadcom card (and have done for years), so this driver is installed for almost anybody using Boot Camp on an Apple notebook. I'd assume this problem would affect anybody using Boot Camp + wifi + a Bluetooth device.
