Symptoms

Consider the following scenario:
  • You have a computer that is running Windows 8.1, Windows Server 2012 R2, Windows 7 Service Pack 1 (SP1), or Windows Server 2008 R2 SP1.
  • You create an environment variable, and you set it to %APPDATA% or %LOCALAPPDATA%.
  • You run the Set command from a command prompt to query the environment variable. For example, if you had set the value to %APPDATA%, you can see the following query result:
    UserVariableName=C:\Users\UserFolder\AppData\Roaming
  • Applications on the computer make some changes to system parameters so that a WM_SETTINGCHANGE message is sent to the top-level windows.
  • You open a new command prompt window, and then run the Set command again.
In this scenario, you receive the following result:
UserVariableName=%APPDATA%
