Defragmenting in vista

[Den807]

hi people, i was wondering, after defraging my 160gb laptop with the vista OS, and using the windows defrag, my hard disk's available space became smaller by about 9-10gb, from 26 it became 27 or 26. any thoughts why this happened? or is this normal?

It's probably a log file.

" from 26 it became 27 or 26" how is that smaller by about 9-10gb? that would reduce it to 16 or 17 gb.

oops that was a typo, i meant 16-17gb haha sori

Most likely culprit using the space would be the system restore points. Each time the system is updated with a new patch or program instalation a new restore point is created, could be a new point was added after defrag.
You can delete the older restore points to make more space. You can also limit the amount of space it uses.
Normally about 15% on each drive is used.
Note that running System Restore requires administrative permissions.
