Everyone who works on a Windows computer has his or her favorite system utilities. But, there are a handful of must-have tools that no Windows user or IT support pro should be without. During this week’s episode of TR Dojo, I give you a list of free Windows utilities that you should download right now.

To keep things simple, I’ve divide the list into five separate categories. And while dozens of applications may fall into each category, the following tools are favorites of TechRepublic members and editors.

1. Cleaners: CCleaner

2. Uninstallers: Revo Uninstaller

3. Defragmenters: (UltraDefrag, MyDefrag, Smart Defrag, and Defraggler)

4. Remote support tools: CrossLoop

5. Password recovery and reset utilities: Offline NT Password and Registry Editor
