How to Edit System Variables in Windows 10

This tutorial will walk you through the steps needed to edit system variables on a Windows 10 machine. These steps are essential for configuring software environments or optimizing system performance.

Step 1: Open System Properties

Press the Windows key, type "This PC," right-click it, and select "Properties."

By right-clicking "This PC" and choosing "Properties," you’ll access a summary of your computer’s basic information, including the Windows version and system type.

Step 2: Open Advanced System Settings

In the System window, click on "Advanced system settings" located on the left-hand side.

This will open the System Properties window directly to the Advanced tab, where you can adjust various system settings.

Step 3: Access Environment Variables

Click the "Environment Variables" button near the bottom of the Advanced tab.

Here, you can see two types of variables: User variables (specific to the logged-in user) and System variables (affecting all users).

Step 4: Edit a System Variable

Select a variable from the System variables list and click "Edit."

A new window will appear where you can change the variable name and value. It’s essential to ensure the new value is correct to avoid system issues.

Step 5: Add a New System Variable

Click the "New" button under System variables to create a new variable.

You can define the variable name and value in the new window that appears. This is useful for adding new paths or settings required by certain applications.

Step 6: Save Changes and Exit

Click "OK" to save your changes, then click "OK" again to close the System Properties window.

Your changes will take effect immediately without needing a system restart. However, some applications may require a restart to recognize the new variables.

After completing these steps, your system variables will be updated, providing a new configuration that can enhance system performance or software functionality.
