1.does windows support that
I have no idea, I've never used --enable-trans-sid on either *nix-variants or Windows, as it's an imperfect solution and can add to server overhead considerably. However, if you have the capability to compile PHP on Windows, I don't see why not.
- can u give that line of code alone please
It's not a line of code, it's a command-line option when you configure PHP for compilation. You would need to add the option to the configure command line:
./configure --enable-trans-sid [other command line options]
