capswitch

Switch keyboard layouts using the Caps Lock, and use the standard Caps Lock function by pressing Shift+Caps Lock.

Supports Windows only.

Quick Start

Downloads, registers a logon task (requesting admin elevation via UAC), and launches automatically:

Start-Process powershell -Verb RunAs -WindowStyle Hidden -ArgumentList '-NoProfile -Command "New-Item -ItemType Directory -Force $env:LOCALAPPDATA\capswitch | Out-Null; iwr https://github.com/oifj34f34f/capswitch/releases/latest/download/capswitch.exe -OutFile $env:LOCALAPPDATA\capswitch\capswitch.exe; schtasks /create /tn Capswitch /sc ONLOGON /tr $env:LOCALAPPDATA\capswitch\capswitch.exe /rl HIGHEST /delay 0000:30 /f; Start-Process $env:LOCALAPPDATA\capswitch\capswitch.exe"'

Install manually

Download the binary from the releases page, place it at %LOCALAPPDATA%\capswitch\capswitch.exe, then open PowerShell as Administrator and create a logon task:

schtasks /create /tn Capswitch /sc ONLOGON /tr "%LOCALAPPDATA%\capswitch\capswitch.exe" /rl HIGHEST /delay 0000:30 /f

Build

Requires Visual Studio Build Tools with MSVC and Windows 11 SDK. Install via winget:

winget install -e --id Microsoft.VisualStudio.BuildTools --override "--passive --wait --add Microsoft.VisualStudio.Component.VC.Tools.x86.x64 --add Microsoft.VisualStudio.Component.Windows11SDK.28000"
