Windows-Tools on CD-ROM (or USB stick)

This list has not been updated since 2007. Links may not work. Use a search engine of your choice.

Having created several bootable Windows CD-ROMs with Bart's PE Builder, I thought how nice it would be if I could use some of the plugins on running systems (i.e. without having to reboot). So in spring 2004 I started searching the Internet for useful utilities that can be run directly from CD-ROM. These were my requirements:

  • Must be available free of charge (at least for non-commercial use). If source code is available under a Free Software/Open Source license, that's even better.
  • Small is beautiful
  • Graphical user interfaces are nice (this is Windows after all...;-)
  • My focus is on diagnostic, network and security tools (no games or MP3 players...)

Here's my list. Download the tools, exctract the archives to a folder on your harddisk and burn them on a CD-ROM. I especially like those cute mini DVD-RWs. Or just put them on your USB-stick. If you leave out all unnecessary files (documentation, language files, etc.) and compress all executables with UPX, all these tools together take less than 100 MB of disk space.

If you have any comments or suggestions write to: mail at dirk-loss de.

Optional: Use the tools together with PE Builder:

If you want a really nice CD-ROM, start Bart Lagerweij's PE Builder, tell it to include the tools folder on the CD-ROM (by entering the path as a 'custom directory' on the start screen) and create appropriate entries for the Nu2menu system. By using PE Builder you can optionally run the tools from a clean (rescue) system running completely from CD-ROM. And you have a nice menu that automatically starts when you insert the CD-ROM into a running Windows system.
