Python, for instance, offers to add the appropriate Python path to your Path environment variable during install.

The same is true for any application you install: The installer is expected to add the appropriate variables to your environment, so you should never need to modify Env: manually. To discover significant variables for individual applications, refer to their user and developer documentation.

November 13th, These environment variables are expanded when the value is retrieved.

To demonstrate this, use the REG utility. This is a small command-line utility included with Windows. Query the TEMP environment variable as seen below. This is the old-school way of showing environment variables via cmd. Know that PowerShell does not recognize this format. The REG utility allows us to see the native value of the registry value. Click on the EnvironmentVariables button, which is highlighted in the image below.

The Environment Variables dialog, shown below, allows you to view, create and modify user and machine-scoped environment variables. Note that the dialog refers to machine scoped variables as System variables. A PS drive allows you to treat environment variables as if they are a file system through the Env: drive.

But to save some keystrokes, switch to the Env: drive just as you would any file system drive, as shown below. You can use the same commands you would use to access a file system, such as Get-Item and Get-ChildItem to access environment variables.

Because environment variables are stored in a PS drive, you can use the tab completion feature of PowerShell to cycle through the available variables, as shown below.

NET objects. You can access a specific value of an environment variable by wrapping the Get-Item command reference in parentheses and referencing the Value property as shown below:. In situations where you need to only return certain environment variables, use standard PowerShell cmdlets such as Select-Object and Where-Object to select and filter the objects returned by the Env: provider.

As an alternative method, use the Get-Content cmdlet. This cmdlet returns a [String] object containing the value of the environment variable. This object is simpler to deal with as it returns only the value, rather than an object with Name and Value properties. Create new environment variables with PowerShell using the New-Item cmdlet. You can see below using the Set-Item cmdlet, you can both create or modify and environment variable.

Sometimes the situation arises that you need to replicate the value of an environment variable. You can do this using the Copy-Item cmdlet. Situations will arise where an environment variable is no longer needed. You can remove environment variables using one of three methods:. In situations where the name of an environment variable needs to be changed, you have the option to rename, rather than delete and recreate with the Env: provider.

Use the Rename-Item cmdlet to change the name of an environment variable whilst keeping its value. Having mastered the Env: drive to treat environment variables as files, this section shows you how to treat them as variables. Another way you can manage in-session environment variables is using the the PowerShell Expression Parser.

Setting an environment variable using this method is straightforward. This will also create a new environment variable if one does not already exist like below. NET class [System. Environment] offers methods for getting and setting environment variables also. This is only method to access various environment scopes directly and set environment variables that survive across PowerShell sessions.

In all of the following examples, if no scope is provided, the process scope is assumed. When using the [System. NET static class methods. Environment] followed by two colons :: then followed by the method. This method returns all environment variables by the scope specified as the method argument in parentheses.

Using the GetEnvironmentVariables method, you use dot notation to reference the value. Enclose the [System. Environment] class and static method reference in parentheses followed by a dot then the name of the environment variable like below:. Note that when referencing environment variables this way, you must ensure you match capitalization! Use the GetEnvironmentVariable instead. Rather than using the GetEnvironmentVariables method, instead use GetEnvironmentVariable to find single environment variables.

It gets around the issue with capitalization and also allows you to specify the scope. Use the SetEnvironmentVariable method to set the value of an environment variable for the given scope, or create a new one if it does not already exist. Note: Calling the SetEnvironmentVariable method with a variable name or value of characters or more will cause an exception to be thrown.
