How to install OWASP Joomscan vulnerability scanner @Windows

To use Joomscan.pl, a PERL interpreter is needed to be installed in Windows.

After installation there should be an ENV variable to be available through CLI, so now open CMD (Windows+R) as an Administrator(!), and type:
cpan
install local::lib
install App::cpanminus
Which installs the compilers, which now needs to be configured:
exit
cpanm install -f Switch

Now, use it:
perl joomscan.pl
