After CCleaner's aggressive registry cleaner screwed up my grandson's computer recently my advice would be to forget tampering with the registry.

As previous posters have said, Windows 7 does a pretty good job of taking care of business.

If it ain't broke, don't fix it. :)
Andy, can you tell us the circumstances of CCleaner messing up the Registry and how you know with certainty it was CCleaner.

The reason I ask is that I have read hearsay about CCleaner messing up the registry for years but never seen a documented case. Meanwhile I've installed it on hundreds of machines representing thousands of uses and never had a single complaint on it's disk or reg cleaner.

Any probs were easily traced instead to viruses, Updates, or other causes - not CCleaner. I'm wondering how you know for sure it's CCleaner which is probably the most universally respected app in the entire tech world.

As far as reg defrag which is the OP's question, I also used Auslogics for years and installed it for many satisfied users of both Disk and Reg defraggers. However I never was convinced there was a benefit, and have since switched to Puran boot-time defragger which gets System files not running at boot and does seem to noticeably help - including a 2 minute startup cut in half after boot defrag was prescribed by our expert Cluberti.
