Working with environment variables in Windows is as easy as:
Win + Pause > "Advanced system settings" > "Environment Variables..."
After which you get a tiny, unresizable, form where you can view and manage them. Something better eventually arrived with Windows 10 but still, PowerShell :)
Use Autohotkey to open the window with
Left Alt + Pause:
LAlt & Pause::Run % "rundll32 sysdm.cpl,EditEnvironmentVariables"
