Controlling Environment Variables

Back in the DOS days you created environment variables to maintain certain settings on your system. These variables were used by applications to find files, and store information about you and your preferences.

These environment variables are still used by all versions of Windows for different reasons. To manage your these variables:

• Right-click on My Computer
• Select Properties from the drop down menu.
  
• Click on the Advanced tab.
• Press the 'Environment Variables' button.

From here you can create, change, or delete user (only effects the current logged in user) and system (effects every user who logs into the computer) environmental variables.
