    When should you run a registry cleaner?


    I'm just curious when you should run a registry cleaner if ever?

    According to someone from Microsoft Answers. Registry cleaners are usually "snake oil" products. Some have claimed that they work (like CCleaner) but I guess its based on opinion.

    Registry cleaners generally cause more problems than they solve and should be avoided. They do have some value when used by an expert to solve a specific problem. But most people who use them have only a vague idea of what the registry is and that is a dangerous combination.

    Basically all of the above are true.
    The Windows Registry doesn't need to be cleaned, it is a self sufficient element of the Windows Operating System.
    The only reliable method of obtaining a 'fresh' Registry is to 'rebuild' it by resetting or re-installing your operating system.

    I had a glitch a while back.
    I can't remember exactly but the Registry cleaner in CCleaner fixed it.
    It was an obsolete entry.

    I have never had anything bad happen because I used it.

    Others may have had a different experience.

    Totally agree, it has saved me several times at least. As far as the registry being self-sufficient, I have to disagree. Anyone who knows how to use regedit can do a search and find all kinds of orphan entries. I am amazed whenever I go in looking for something specific but come across entries from a year ago from programs that I uninstalled using the software uninstaller provided by the program.

    This is definitely one of those things people have much different experiences and opinions on.

    If someone regularly does image backups before messing around with stuff like the registry, then I say -- go at it and see if it does any good. But ... the sorry fact is that very few folks take these kinds of precautions, and the ones that just run registry cleaners without any restoration capability are asking for problems.

    The registry acts like a database, in that it contains values that are used by apps and the OS. When you remove an app, all the remaining registry values that were not removed only take up space. And, in today's world of multi-GB hard drives, that amount of space is trivial.

    If you corrupt the registry, there's a good chance that Windows will not even boot -- and you've "broken" the PC all to save a little bit of space.

    So, without restoration capability, my advice is to leave well enough alone.

    I keep 2 Macrium images all the time.

    Then again, you can export the registry & put it back if you mess it up.
