Windows 10 has made a lot of changes from previous versions, one of which is that you can no longer view System Properties as a non-admin user. This means you can no longer view/edit your user environment variables via System Properties.

There are 3 ways around this:

  • Use another method such as set or Powershell or direct registry editing
  • Go to Control Panel->User Accounts->Change My Environment Variables
  • Run "C:\WINDOWS\System32\rundll32.exe" sysdm.cpl,EditEnvironmentVariables to envoke the Environment Variables window directly
