Variable PATH

The PATH variable is the list of folders the system searches through for the programs matching the commands you type. When you type git in PowerShell, Windows scans every folder in the PATH until it finds git.exe. The infamous “is not recognized as a command” message almost always means the program is indeed installed, but its folder isn’t in the PATH — or the terminal was opened before the install happened. Simple fix: close and reopen PowerShell after installing Git or Node.js, the new window will load the updated PATH.
