Why would you do that?

It's because since in Mac OS X Lion, they've reversed the wheel scroll direction. I've always reversed it back in system preference. Then I've upgraded it to Yosemite and didn't bother to change it. I just change myself to follow it. A few days later, the Mac mouse scroll wheel direction became natural to me.

Now I have a problem with my work PC, which is Windows Server 2012. Whenever I scroll the page with the mouse, the page goes in the opposite direction and it really annoys and confuses me.

So, now you need to reverse the mouse wheel scroll in windows. How can you do that?

You have to edit a registry, unfortunately, but there's a powershell script that does it for you. Of course, you shouldn't run any script you find on Internet in your admin elevated powershell shell. But I took the risk and did it. This is the script.

Get-ItemProperty HKLM:\SYSTEM\CurrentControlSet\Enum\HID\*\*\Device` Parameters FlipFlopWheel -EA 0 | ForEach-Object { Set-ItemProperty $_.PSPath FlipFlopWheel 1 }

Good luck and enjoy the inverted direction of the mouse scroll wheel.
