Top free tools for Windows: Revo Uninstaller Freeware
Download: Revo Uninstaller Freeware
Purpose: Uninstalls programs
Platforms: Windows 7, Vista, XP
Cost: Free; additional features in Pro version, $39.25, or $19.62 each for four or more computers
Revo Uninstaller well and truly uninstalls programs, and it does so in an unexpected way. When you use Revo, it runs the program's uninstaller and watches while the uninstaller works, looking for the location of program files and for Registry keys that the uninstaller zaps. It then goes in and removes leftover pieces, based on the locations and keys that the program's uninstaller took out. Revo also consults its own internal database for commonly-left-behind bits and roots those out as well.
Revo gives you a great deal of flexibility in deciding just how much you want to clean and what you want to save. For most programs, the recommended Moderate setting strikes a good balance between defenestrating problematic pieces and deleting items that really shouldn't be deleted.
The not-free Pro version monitors your system when you install a program, making removal easier and more complete. Pro will also uninstall remnants of programs that have already been uninstalled.
Top free tools for Windows: Paint.Net
Download: Paint.Net
Purpose: Image editor
Platforms: Windows 7, Vista, XP (requires .Net Framework 3.5 SP1 or later)
Cost: Free
With dozens of good -- even great -- free image editors around, it's hard to pick one above the others. IrfanView, for example, has tremendous viewing, organizing, and resizing capabilities. GIMP ships with powerful tools and an enormous array of add-ins. FastStone Image Viewer lets you edit full-screen and has a screen capture capability. That doesn't even brush the surface of the Picasa vs. Windows Live Photo Gallery maelstrom -- a religious debate worthy of several volumes.
For powerful, easy-to-use photo editing, with layers, plug-ins, and all sorts of special effects, along with a compact and easily understood interface, I'll stick with Paint.Net. Although it requires Windows' bloated .Net Framework, the program puts all of the editing tools a nonprofessional might reasonably expect into a remarkably intuitive package.
