The “System Properties” screen opens. Click "Environment Variables" at the bottom right of the screen.

The screen will look like this. You can check and change the Windows system environment variables in the "System environment variables" column. Click "New" to add a new environment variable. Select any environment variable and click "Edit" to edit the environment variable. You can also click "Delete" to delete the environment variable.

Click "New" and you will see a screen like this. Enter the name of the new system environment variable in the "Variable name" field, and enter the value you want to set for that system environment variable in the "Variable value" field. Click "OK" to register.

For example, if you select the environment variable "Path" and click "Edit", the screen will look like this. When specifying multiple paths, separate them with ";", but on this screen each item can be edited line by line.
Select any line and click "Edit" to edit that line. Click "Up" or "Down" to change the position of the line. You can change the priority of items.
If you click "Edit Text", the display will be similar to the "New" screen above. All items can be edited with ";" connected.
