If you’ve got used to Mac OS X Lions reversal of the trackpad and you’ve just installed Windows 8 on your macbook, scrolling becomes a bit confusing.
Open up a regedit (WinKey-R / cmdKey-R)
Do a search for FlipFlopHScroll or FlipFlopWheel, change both values to a 1 instead of a 0 and reboot.
Keep doing that Find until you’ve caught all the values.
Once you’ve booted, windows scrolling will act like the default trackpad settings for Lion. 😀
