文章来自： Inverting direction of mouse scroll wheel 的回复，by slhck。

There is a registry setting named FlipFlopWheel that does this! HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\HID\VID_???\VID_???\Device Parameters. There might be multiple mouse entries. The default value for FlipFlopWheel should already ready 0. Change into 1 to invert scrolling. Reboot or possibly replug in mouse for changes to take effect.

To get the VID_??? number you have two options:

1. Go to the mouse control panel, click the Hardware tab, then click Properties.

   Now in the HID-compliant mouse Properties window click the Details tab and select the Device Instance Path property. The registry path is in there. You only have to unplug and plug back in my mouse for this to take effect.

2. Run this in PowerShell (from Start » All Programs » Accessories » Windows PowerShell):

   Get-ItemProperty HKLM:\SYSTEM\CurrentControlSet\Enum\HID\*\*\Device` Parameters
