Windows 7 built in defrag

I use the free Auslogics Disk and Registry defraggers monthly after CCleaning Disk and Registry.

Have never had any issue with any of these in hundreds of installs over ten years.

They are the state of the art.

I never use registry cleaners of any sort. Had a real bad experience when I tried one and it nuked my XP system a few years ago. Luckily had an external backup image to restore from, otherwise it would have been a royal pain reinstalling all the programs

When using W7 built in defrag what doesn't it defrag or if easier to post, what does it defrag.

IIRC, it doesn't defrag some (many?) of the system files, page files, fragments larger than 64 MB (in default mode) and if disk space is low (< 15%) it will have trouble defragging in general.

There are a bunch of sales operation scam registry cleaners that pop up in web ads that are harmful. They give true genius apps like CCleaner a bad name.

I've also used CCleaner Registry cleaner for ten years now hundreds of times without a single issue. Those who claim it messed up their system usually have another possible cause.

The issue can be settled by simply backing up the Reg files cleaned as offered each time it runs. If an issue arises, merge them back in to see if this is the cause, or if computer won't boot then System Restore from DVD/CD.

Layback,
