Problem With Hard Drive T61

Hello I'm from Mexico, I bought on june last year my T61, with vista business installed

I have the next problem, the hard drive that I bought only have 68 gb, when I received it there only was 20gb of free space (the windows and the lenovo software take too long space?)
anyway I have not install so many thinks except for windows office 2007 and two or tree applications
a week ago I have only 10 gb of free space, yesterday morning I only had 6 gb free space and for the evening I had only 1.6 GB
I have been doing nothing and I don't know if some application precharged or the vista itself is eating the free space itself?
I have run my antivirus and my anti spyware and didn't detect any treath

someone have any answer to my problem?

 

That's why they don't like Vista at all
Something's wrong with your machine. Maybe that's the way Vista using to cache files or you edit video files or windows auto restore programme schedule too neat.
Firstly, you need to turn off restore function or reschedule it as you need.
After that, empty temp folder or video files that you edit.
Hope this help.
