David Golden released an early version of a binary distribution of Perl for Windows called Strawberry Perl The POD says:

The purpose of the Strawberry Perl series is to provide a practical Win32 Perl environment for experienced Perl developers to experiment with and test the installation of various CPAN modules under Win32 conditions, and to provide a useful platform for doing real work.

A problem that arises when you install Perl modules from CPAN are XS modules that need to be compiled. Strawberry Perl solves that problem by including a compiler and a set of pre-installed modules.

Although Strawberry Perl is still in Alpha and not recommended for production usage, it is great to have a Perl distribution that aims at delivering the same power Perl has on Unix to our unfortunate colleagues using Windows.
