Can the environment variables tool in windows be launched directly?
Solution 1:
Starting with Vista, the panel can be displayed from the command line (cmd.exe) with a
rundll32 sysdm.cpl,EditEnvironmentVariables
from here
Solution 2:
I recommend this: Open "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.
Update:
Win 7: Start menu -> in search bar, type "system variables" and enter, you will have the Advanced tab of the system properties window open.
Win 8 and later: Simply type the above in the search box in the task bar.
Solution 3:
Open notepad, copy below line and save it as "SysPropAdv.bat". Run on cmd prompt, It will open a system properties window.
start SystemPropertiesAdvanced.exe
