Windows 防火墙和 %USERPROFILE% 变量

Question

I've discovered that using system variables as %USERPROFILE% in Windows Firewall path definition like %USERPROFILE%\op\opera.exe makes the firewall doesn't work for such defined application. Changing the path to an explicit definition like C:\Users\Mark\op\opera.exe does work. My question is why can't one use %USERPROFILE% var in the firewall path definition?

Answer 1

Firewall can't know which user's profile %USERPROFILE% environment variable point, it should know the exact path of the application to find it. Especially, if no user logged in, %USERPROFILE% points to where?
