These free software programs for Windows are some of the easiest to use for certain tasks. I figured I would post them here to let the Windows users that come here that they are not left out. Maybe it will convert some curious users to give Linux a go.
1. FreeZip is a small, fast and efficient Zip utility for compression and decompression of files and directories. FreeZip integrates with Windows Explorer and uses file associations and context menus to zip or unzip files and subdirectories. If you know how to use Windows Explorer, then you do not have to learn anything new to use FreeZip. The setup is a single-click process and there are no options or settings involved. The manual is in English, Japanese, Polish, Italian, Swedish, German, Latvian, Spanish, French, Hungarian, Czech, Russian, Lithuanian, Belorussian, Portuguese and Chinese.
2. Winmd5sum is a easy utility to check your downloaded md5sum for data integrity.

3. Imageburn is a lightweight CD / DVD / HD DVD / Blu-ray burning application that everyone should have. (So you can burn a Linux ISO or whatever)
4. Foxit reader is a very nice. lightweight, (doesn't gobble up hardrive space), alternative to Adobe Reader.
5. K-Lite Mega Codecs Pack.
With the K-Lite Codec Pack you should be able to play all the popular movie formats and even some rare formats.
I hope this makes your computing needs easier, and to show that software doesn't have to be bought to be good software. Enjoy
