Guidelines for Using Operating System Variables on Windows Endpoints

Valid on Windows

A CA Access Control operating system variable (ACVAR object of type osvar) uses the value of a Windows environment variable.

You should observe the following guidelines when you use operating system variables on a Windows endpoint:

• The environment variable must be a system variable.
• If you change the value of a Windows environment variable, CA Access Control does not recognize the change until after you restart it. In some releases of Windows, you must also restart the computer for any Windows service and CA Access Control to recognize the change.
