I originally joined this forum to mention my problem with the .068 beta Defraggler. After downloading and install, the program just would not defrag. I didn't bother to post the problem, in case it was something unique to my computer. I figured it would go away with the next release and it did. Now with the latest RC1 I can report no problems. No matter the complaints, Defraggler just is faster and better it seems than the default windows defrag program in Vista. I appreciate the effort Piriform makes with its freeware products. CCleaner surely cleans out the crap, purging cookies, cache bloat, etc. as often as you want. All the stuff offered will only improve over time.
