By default, most of these programs will add their own custom shortcuts to the Windows environment variables. The most used environment variable in Windows is probably the PATH variable. It basically allows you to run any executables that are located inside the paths specified in the variable at the command prompt without having to give the full path to the executable.

To get started, right-click on the Computer or This PC icon on the desktop and select Properties.
On the System dialog page, you’ll see an Advanced system settings link on the left-hand side.
This will bring up the System Properties dialog, which should already be open to the Advanced tab. Go ahead and click on the Environment Variables button at the very bottom.
On the Environment Variables dialog, you’ll see two sets of variables: one for user variables and the other for system variables. Both lists have the PATH variable, so you have to decide which one to edit.
If you only need the commands for your own user account, then edit the user variable. If you need it to work across the computer system regardless of which user is logged in, then edit the system variable. Click on Path and then click on Edit.
On the Edit environment variable dialog, you’ll see a list of all the paths that are currently in the PATH variable. As you can see, Node.js and Git already added their paths so that I can run Git commands and Node.js commands from anywhere while in the command prompt.
To add a new path, simply click on New and it’ll add a new line to the bottom of the list. If you know the path, simply type it in or copy and paste it. If you prefer, you can also click Browse and then navigate to the desired path.
To edit any path, simply select it and then click on the Edit button. You can also delete paths using the Delete button. Note that you can also move items up and down on the list. When you type a command at the command prompt, Windows has to search through each directory stored in the PATH variable to see if that executable exists or not. If you want your executable to be found faster, just move that path up to the top of the list.
This can also come in handy if you have multiple versions of the same command in different paths and need to have one run instead of the other. The one that shows up higher in the list will be run when you type in the command. Lastly, if you click on Edit text, it will load a dialog where you can edit the Path variable using the old interface where all the paths are listed in one text box.
