JSI Tip 6804. What is the order of environment variable definition during system start up / log on?

Environment variables are set in the following order:

1. Dynamic variables that the operating system defines, like %DATE% and %TIME%, are established first.

2. System variables from Control Panel / System are set next.

3. Autoexec.bat variables are next, unless you have ignored them.

4. User variables from Control Panel / System are set last.

NOTE: If the same variable is defined in multiple places, the last value set takes precedence.
