'Solution to "EMFILE: too many open files" in Windows'

I just moved my blog to hexo and ran into the “EMFILE: too many open files issue”. The hexo issue page recommends you run ulimit, but that doesn’t work on Windows.

After trying a ton of different things, I finally fixed it by upgrading to the latest version of Node.js v6.9.3.

Solution: Upgrade Node.js to at least v6.9.3
