I have started to use Fluxbox on my personal laptop. I like it so much that I will soon make the change for my work computer (yes, I am allowed to use Ubuntu at work).
Fluxbox is a extremely light desktop environment for Linux and I found it by chance when using ophcrack live cd at work to solve a problem trying to crack a windows password from an old computer.
You can try it without messing anything on your Gnome or Kde setup. Just do:
sudo apt-get install fluxbox
Then logout and select "Fluxbox" as your session before you login.
This file is my (ongoing) effort to start customizing shortcuts.
Just a note to new users: the menu is found by right clicking on an empty space on your desktop.
I had to stop using fluxbox since I was too used to Gnome :(
I'm not sure when you posted this since there is no date, but are you still using fluxbox?
I trust windows password reset 7.0 It works fast and reliable.
I've used a software to reset my windows password from the Windows Geeks.
I tried other products before and only this one would work.
