7-Zip is a very simple yet powerful archive utility with extensive support for multiple formats. This free file archiver features an extremely easy to understand interface and common functions, but its greatest strength lies in the unique compression capability it offers. 7-Zip has been designed to reduce the size of different types of files (Word documents, Excel spreadsheets, images etc.) thus achieving a file which can be up to five times smaller than the original. 7-Zip uses the new 7z compression format, which compression rates are up to 50% better than standard ZIP, without any quality or speed loss.

So, I downloaded 7-Zip in its latest version (9.09 beta) and installed it under the Windows 7 environment in order to test its behavior and compatibility, and what you are about to read is the results of such testing.
