Environment variables can be helpful in many scenarios, but they’re particularly useful if you’re an IT person or you’re fixing someone else’s computer, as you can quickly navigate to certain locations without even knowing the username or full path to a system folder. For example, instead of browsing a path like “C:\Users<UserName>\AppData\Roaming,” you can open the Run command (Windows key + R), type this variable “%APPDATA%,” and press Enter to access the same path. Or you can use the “%HOMEPATH%” variable to access the current user default folders location — where the operating system stores the folders for Desktop, Documents, Downloads, OneDrive, etc. In this guide, you’ll learn the list of the most common environment variables you can use on Windows 10.
Windows 10 default environment variables
Although you can use environment variables to access certain locations within Windows 10 quickly, you’ll typically use these variables when building a script or an application. Keep in mind that some of the variables mentioned are not location-specific, including %COMPUTERNAME%, %PATHEXT%, %PROMPT%, %USERDOMAIN%, %USERNAME%. While this guide is focused on Windows 10, it’s important to note that these variables will also work on Windows 8.1, Windows 7, Windows Vista, and Windows 11. You can always view all the environment variables available on your device using the Get-ChildItem Env: | Sort Name PowerShell command.
