    You can clean junk files (emptying temporaries) safely and that has some benefit. Cleaning the registry however does not improve the performance of the machine and can cause many problems with your computer. See this TSG library article for a bit more information.

    As to defragmenting the drive, the Windows defrag tool does a fine job. One thing that some people dislike about the Vista Defrag tool is that it shows you very little information about how fragmented the drive is in the first place. However the defrag tool can be configured to run on a regular schedule and then effectively forgotten about - barring only the chance that your computer is always off when a defrag is due.

    The other reason that some people go for third party defrag programs is that they are very good at fudging the numbers to make it look like they make a difference. In particular the Vista tool will not, by design, move any fragments larger than 64 megabytes as they have no noticeable effect on performance and defragging will only strain the drive. The 3rd party tools will claim that all of these are problematic fragments and your drive is perhaps an additional 25% fragmented on top of the real value. (The thing about big files is that they come to 25% quite quickly.)

    My advice is the following:
    Remove and do not use registry cleaners on your computer.
    Set up the Vista defrag to run on a weekly or monthly schedule.
    Spend your effort on other more valuable things, such as avoiding malware.
    Just get on with using your computer.

    You have to understand that when a dive is fragmented it means the files on the drive are broken up over different bits of the drive. You therefore waste time moving from the location of the first part of the file to the location of the second. Defragging simply means reorganising the drive so that all the files are contiguous--the whole file in one section.

    From Vista on Microsoft decided not to defragment files where the fragment itself was larger than 64 megabytes. They realized that it is too much work for the hard disk to have to move 64 megabyte chunks around, and the benefit of doing so it is practically 0.

    Now let's say that you might have 4 video files on your drive, about 1GB each. Each is split into 2 sections in different places on the drive. Microsoft's study has determined that it doesn't help to defrag them, and its tool will rightly leave them in place. However if you ran a third party tool it would claim that you had 4 gigabytes of "fragmented files" on your drive and promise to fix them. They're decision is wrong, but many people will assume that they are superior to the Microsoft tool which apparently didn't even see the fragments.
