I recommend this: Open the "Run" prompt → type "SystemPropertiesAdvanced". You will be on the Advanced tab of the System Properties window. From here it's easy. I feel this is an easier command to remember than the command prompt's and a good shortcut.
Windows 7: Start menu → in the search bar, type "system variables" and Enter. You will have the Advanced tab of the system properties window open.
Windows 8 and later: Simply type the above in the search box in the task bar.
