Reverse Mouse Wheel scroll in Windows 11

Chose between natural mode like MacOS or Windows default mode.

Step 1: Open Windows PowerShell in Administrator Mode.

You can do this by going to Start Menu, type PowerShell, and click Run as Administrator.

Step 2: Copy the following code and paste it in the command line of Windows PowerShell:

$mode = Read-host "How do you like your mouse scroll (0 or 1)?"; Get-PnpDevice -Class Mouse -PresentOnly -Status OK | ForEach-Object { "$($_.Name): $($_.DeviceID)"; Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Enum\$($_.DeviceID)\Device Parameters" -Name FlipFlopWheel -Value $mode; "+--- Value of FlipFlopWheel is set to " + (Get-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Enum\$($_.DeviceID)\Device Parameters").FlipFlopWheel + "`n" }

Nvm does not work in vscode tasks, because tasks are run without a shell. .bashrc is not loaded and the nvm command is unknown.

My solution uses a wrapper script around /bin/bash that reads in the correct node version from .npmrc in the project folder.

#!/bin/bash

set -e

if [[ "$2" == nvm* ]]; then

export NODE_VERSION=v$(cat .nvmrc)
