Utilities

1. Ultra Defragmenter
This degrag tool’s claim to fame is its incredible speed. It has a small footprint and the unique ability to defrag your drive while you are booting up.

2. Startup Manager
Get control over the Windows startup process. Startup Manager lets you decide which programs load at Startup—potentially speeding up the process.

3. HDGraph
Wondering how in the world you managed to fill up 80GB worth of hard drive space? HD Graph lets you see the reasons in a flash by drawing a multi-level pie chart that details how much space each directory and subdirectory is consuming.

4. Windows Powertools
Want to speed up your PC? Windows Powertools contains 16 utilities for improving your PC’s performance in one convenient package. Utilities include Cache2Trash (for deleting temporary files), DiskCheck (finds and resolves disk errors), Defrag (defragments your drive), Kompressor (compresses your hard drive), and more.

5. KShutdown
The normal Windows shutdown procedure from the Start menu works fine most of the time, but Kshutdown adds a lot of extra features. Most useful seems to be the delay option which lets you shutdown or restart your system at a later date or time.

6. 7-Zip
This file compressor supports the 7z format to pack files into a smaller package than can be achieved with either the ZIP or GZIP formats. If you prefer, 7-zip can also create ZIP, GZIP, BZIP2, and TAR files and de-compress from nearly all compression file formats.

Video Tools

7. Movica
This graphical video editor let you edit WMV, FLV, RM and MPG files. The features are pretty basic, but you can edit, join, or split movies to your heart’s content.

8. DVDx
Calling itself “likely the most popular DVD backup software worldwide,” DVDx converts your DVDs into (S)Video CD, DivX, or Windows Media files in order to save file space. The Ultra Edition, available for a fee, can handle copy-protected movies, though, of course, you should only use it if you have legal permission to copy those movies.

9. Handbrake
Handbrake does just one thing—converting DVDs to MPEG-4 files—but it does that one thing pretty well. It’s still in the early stages of development, but the latest version has greatly improved performance and fixed some of the bugs that hindered earlier versions.
