Both Net::SSH2 and Net::SSH::Perl can be installed on Windows, though doing it is not easy, specially with ActiveState Perl.

Net::SSH2 is included with Strawberry Perl.

Net::SSH::Any does not handle the SSH connection by itself but delegates it to some module implementing the SSH protocol (currently Net::SSH2 or Net::OpenSSH) or to some external command as plink or ssh. Every backend has its limitations. For instance, only a few ones support password authentication.
