PDF Architect is a powerful editor for Windows, with tons of great features. This free PDF tool comes with Windows Server 2008, so it will run on either Windows Vista or Windows XP. They're placed behind many other paywalls, too. The first tier has just the bare essentials, including a few basic functions. You can read and edit any PDF file and make them from more than 300 different sources.
Features you can get for your own PDF Architect package plus what else you might be able to find for an even lower price if you want to do a lot of editing and customization. The first two tiers offer the usual fixes and features that are required if you want to do more than just open, edit, and view PDF files. One-click "print" functionality, wildcard searches, sorting by date and time, labels and auto formatting, and a lot more are all available in this very useful and powerful application. With all this capability, it's no surprise that PDF Architect is widely used and a favorite among PC users around the world. The fact that PDF Architect comes included with Windows Server 2008 is really a big plus, too, especially since most people don't know anything about installing programs like this on their machines.
PDF Architect isn't a virus, either, because it's part of the Microsoft Office Suite. All you have to do to remove it is to download and install its small toolbar on your Windows machine, which will then allow you to launch all of its features. One of the best features, however, is its built-in "revision history," which lets you undo any changes you've made in PDFs using your own copy or your employer's copy of this same PDF. This way, you can always make sure you haven't done any harm to your PDFs and they'll always be safe for reference. PDF Architect truly is a great tool for PDF creation, revision, and safety.
