To view and set the path in the Windows command line, use the path command.

What is the default Windows %PATH%?

The path is based on programs installed on the computer, so there is no «default path.» However, the Windows minimum path is often the path below.

Keep in mind that as you install programs, the path is updated with the paths for the newly installed programs. So, if you have erased your path after installing other programs, those programs may be affected.

Setting path in the MS-DOS and Windows command line

To view and set the path in MS-DOS and in the Windows command line, use the path command.

Set PATH and other environment variables in Windows 10

In older windows systems you had to navigate to Advanced System Settings in Control Panel to view, edit or add environmental variables.

• Windows XP — Right-click My Computer, and then click Properties → Advanced → Environment variables → Choose New, Edit or Delete.
• Windows 7 — Click on Start → Computer → Properties → Advanced System Settings → Environment variables → Choose New, Edit or Delete.

In Windows 8 and 10, you can navigate to Advanced System Settings in a similar way.

• Windows 8 — Right click on bottom left corner to get Power User Task Menu → Select System → Advanced System Settings → Environment variables → Choose New, Edit or Delete.
• Windows 10 — Right click on Start Menu to get Power User Task Menu → Select System → Advanced System Settings → Environment variables → Choose New, Edit or Delete.

However, in Windows 10 you can directly get to the Environment Variables window using Search the web and Windows box next to the Start menu. Type environment variables in Windows Search box which gives you two options in search results:

• Edit the system environment variables
• Edit environment variables for your account.

Choose either option and you can add, edit or delete environment variables like PATH.

Set environment variables from command prompt

You can set environment variables from Windows Command Prompt using the set or setx command. The set command only sets the environment variable for the current session. The setx command sets it permanently, but not for the current session. If you want to set it for current as well as future sessions, use both setx and set.

For example, you can set the PATH environment variable permanently (current and future sessions) as below:

To view the current path, run:

1. By default setx sets the variable in the local environment (Under HKEY_Current_User Registry key). If you want to set the system variable (Under HKEY_LOCAL_MACHINE registry key), use the flag /m. Start the command prompt as administrator on Windows 10, right click on Start menu and select Command Prompt(Admin).
2. The maximum value allowed for a enviroment variable is 1024 characters. So if your variable is long and you try to append to it with setx, you may get a truncated result.

Set environment variable by Registry edit

If your PATH variable is too long, then the best method would be to edit the registry.

For user environment variables, change the key HKEY_CURRENT_USER\Environment . For System Environment variables change

Add, Edit or Delete the environment variable you want to change, then reboot to activate the changes.

Windows CMD: PATH Variable – Add To PATH – Echo PATH

PATH is an environment variable that specifies a set of directories, separated with semicolons ( ; ), where executable programs are located.

Info: To see the changes after running setx – open a new command prompt.

How to Add to Windows PATH Environment Variable

Works for Windows 10 or 7

If you’re a coder or programmer, you probably spend a decent amount of time using the command prompt to execute programs or compile code. In order to complete those tasks, you most likely have to use a command from a library or software package installed (like Python) on your system.

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.

In this article, I’ll show you how you can add more paths to the Windows PATH variable in case you want to run executables from your own custom directories. It’s worth noting that the procedure below is for Windows 10, but it’s almost exactly the same for Windows 7 also.

Add Directories to PATH Variable

To get started, right-click on the Computer or This PC icon on the desktop and select Properties. If you don’t have that icon on your desktop already, you can add any missing desktop icons easily.

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.

That’s all there is to it! If you want to learn more about environment variables, make sure to check out my post on how to create your own custom environment variables. Enjoy!
