Kexi 
There have been a lot of people over the last few months who have been quite clear in stating that they do not feel Open Office Base is a solid replacement for Microsoft’s Access. My answer to these individuals is to look into Kexi instead. It offers a solid, consistent UI, an active community of users and a future that looks pretty darn bright to me. I see this cross-platform data management application as a means of freeing your company from an otherwise expensive alternative.
VirtualDub
Video editing for Windows is certainly not limited to the Windows Movie Maker. VirtualDub allows its users a clean, user –friendly tool to capture, edit and produce their videos without sacrificing quality or spending any money on an application with unneeded features. Thanks to VirtualDub, which rovides decent documentation and frequent revisions, this is one of the better, yet lesser known open source video editing applications for the Windows OS.
WinMerge 
Personally, I am shocked that this program is not OEM released into every Windows desktop released from the factory floor. WinMerge does a fantastic job at helping to manage projects, making sure that the data inside the file is always the newest, not just the file itself. For example, take two of the same files and use the program to compare them. You’ll see, instantly, using colors to guide you, which syntax has changed and which is missing from one file vs. another. This is a have must for programmers and web designers.
Pentaho BI Suite 
Business intelligence is not a minor issue for most companies – having a solid open source application that can legitimately compete with the big boys is nothing to sneeze at. Pentaho Open BI Suite provides businesses with enterprise class tools to help in this critical data gathering. Reporting, analysis, dashboards and process management: the Pentaho suite does it all.
