117,481 | 117,938 | How can I update Perl on Windows without losing modules? | At work I'm using Perl 5.8.0 on Windows. When I first put Perl on, I went to CPAN, downloaded all the sources, made a few changes (in the.MAK file(?) to support threads, or things like that), and did nmake / nmake test / nmake install.
