HDD Leak on DV9500t

In the past two weeks my HDD has mysteriously used up almost 11GB, and I haven't installed any new programs. My laptop doesn't have any other problems.
I remember reading a fix for this a while back but can't remember where it was.
The problem first occured after doing a clean install.
Thanks in advance for any help.

 

It's normal.

Say two Hail Microsofts and three Our Bills and move on..


Seriously though, vista performs a number of housekeeping backup processes that consume hard drive space, from indexing, shadow copying, temp files, and restore. You can be really anal and go about recovering the space taken up by disabling many of the processes, or deal with the nuances that is Vista. The amount used is dynamic, in that it only uses a prescribed percentage of unused space(for the most part), and will delete dynamically older unneeded information to maintain that percentage and keep from overburdening. It its still incumbent on the user to do his/her own housekeeping by deleting temp files that don't get purged, and delete other files that get missed by the imperfections of the OS. Welcome to the wonderful world of bloatware.

Yes it's an annoyance, in fact one of my pet peeves that just about every software vendor in existence presumes that the unused HDD space and memory is for THEIR software. Just about every program you install today, assumes without asking, that it's just fine to install a background process that runs when booting.
