I've posted v1.5 of Munin Node for Windows.
Summary
Munin Node for Windows AKA munin-node-win32, is a Windows client for the Munin monitoring system.
It is written in C++ with most plugins built into the executable. Which is different from the standard munin-node client, which only uses external plugins written as shell and Perl scripts.
