How to get to Environment Variables from Run

Try using this: "C:\Windows\system32\rundll32.exe" sysdm.cpl,EditEnvironmentVariables

For more details check these links: [1] and [2].

Press Start, type Path, and click Enter to select Edit environment variables for your account.

I know its not strictly using run but it works and literally takes less than 2 sec.

You can shorten your path

• by doing Run... -> "SystemPropertiesAdvanced"
• or press WIN+R and then type SystemPropertiesAdvanced

that will bring you two steps closer.
