When I started my computer up this morning, KPF warned that my trial period was almost done. Trial period? It’s supposed to be free for home users…

Apparently that’s changed in the new version.

” After installation, KPF works as the full edition for 30 days, after which it becomes the limited free edition. … Limited free edition does not provide the content filtering capabilities such as blocking pop-up windows, ads, VB scripts, cookies, etc. and other extra features. Please see the comparison table for more details.”

It’s mostly just the content filter and a few other little things that stop working after the first thirty days. You can easily compare the free version against the full paid version, as well as version 2.1.x. Take a look at that and figure out which one suits you best. Also note that you get a 12 month subscription for updates and upgrades when you register, not the old-fashioned type a license for the current major version. You might end up with v4.0.0.0.1 after that year, or you might end up with v6.5.
