On Windows 7 (or Vista) I use
Outpost 6.7 (2009/07/23 13:08)
Agnitum Ltd. released new versions of their Outpost products. Even if this is not a major release, 6.7 series might be interesting for many because of its support of Microsoft's new operating system Windows 7, which final version should be available in autumn this year. Another interesting improvement in new Outpost is that the content filtering is now fully compatible with P2P clients and rich-media websites.
