I just made an upgrade from Vista to Win 7 ulitmate.
My SSD Drive is 57.5 GIGs which is my OS drive. There is an old hidden partition on it.
Previous install (Vista) used 28 GIG.
When I upgraded to 7 the total use is now 51 GIG.
I have hardly no software installed on that drives.
The funny part is when I boot up, the drive properties windows sometimes shows up 29 GIG used. That happens once every thrid boot.
I tried everyting to clean that drive but it seems that I missing one item somewhere.
SO my question is : How can I make sure that my drive is clean?
