By default the strawberry perl path is not added into PATH env variable

Are you sure?

I've installed Strawberry Perl a couple of times recently. One Windows 10 desktop and one Windows 11 laptop. In neither case did I have to set the PATH variable. I did have to change the association of *.pl and *.pm from perl.exe to a text editor.

I'm not near either of those machines right now. But this Windows 10 machine has Strawberry Perl installed and there are 3 Strawberry Perl paths in PATH. It was installed a long time ago but I don't recall setting PATH manually.
