Vista - Hard drive full but isn't

My hard drive all of a sudden has decided to show its self as full and
filling more every minute. I have a new 3 month old HP laptop with a 140 GB
drive. I don't have anything that is taking up any amount of space and have
done everything possible to free up more space. I have deleted the old system
restore and shadow files , cleaned up the drive and deleted cookies and tepm
files along with every unused program i had there is almost nothing in the
drive except what came in it and about a dozen or so very small programs i
had installed. Even now as i have been on this site it has gone from 21% free
down to less than 19% and by the end of the day it will be full again. Any
ideas as to what would be causing this to happen. Just a few days ago it was
at 45% free.

Hi Tigeress,

On HP computers, besides Vista's System Restore, they have a program called HP Recovery Center. It acts like system restore to and can use up hard drive space. You can uninstall it through Programs and Features, or adjust it's settings.

Hope this helps,
