    I really wish Microsoft would release a registry cleaner for Windows 10. I find it hard to trust 3rd parties with this... as I allowed CC Cleaner to "have at it" a few years back and I ended up with registry problems.

    I decided to "check out" CC Cleaner's registry cleanup feature. I backed up my registry and then ran it. I allowed it to remove Missing / Shared DLL's, ActiveX, Class, and Type issues only. I then ran it again after that... and it found more. Ran again & found more. So... that bothers me. Why didn't it find everything on the first pass? It makes me wonder if it's causing additional issues by removing entries, or if the criteria search isn't comprehensive.
    Short answer.... there are dependencies. Like a tree level. First pass thru, it will detect level 3, for example. 2nd pass, since unused level 3 are gone, now level 2 is unused, and so on. Has to be checked bottom up, not top down.

    I'm giving an explanation of the "why", not a recommendation to do it.

    Thanks, F14. That makes sense to me. A manual check of registry issue findings does confirm that programs can easily leave behind "garbage" entries that causes registry bloat. Seems Microsoft even does this. For instance, SilverLight. I still had it installed, but there was a bunch of garbage entries for an older version.

    What utility would you recommend for registry "cleanup" and integrity check?

    There was a time when Microsoft had a registry cleaner available for download. It was last updated in 1998. It was later removed because it caused problems with some popular Microsoft software. Microsoft learned their error and don't expect it to be repeated.
    There really isn't anything wrong with registry cleaning - if it could be done reliably. The problem is that it can't. There is nothing about a registry entry that reliably associates it with a particular application. Applications use the registry in some very unusual ways so it is impossible to determine with certainty if an entry is in error. As a result a registry cleaner must make frequent guesses. Usually they will be right, but sometimes not. Just one mistake and an important application may not run at all or behave in unpredictable ways.
    The benefits of regular registry cleaning are found primarily in the ads for registry cleaners. In the real world they remain as elusive as ever. There are no reliable studies that confirm it's value. But there is more than ample evidence that it can cause serious problems.
    Yes, I remember that, Microsoft's registry cleaner. It generally worked most of the time, but yeah... it did end up creating problems. Rather astonishing. But today, the registry structure has evolved quite a bit since 1998. I would expect that internal management is "cleaner" and that any kind of correction required would be cleaning up after other programs. And given how the windows system is pretty much protected now, it should be possible to deal with those entries without disturbing system functions.

    The thing is, aren't programs these days generally "intelligent" enough to correct or add registry entries if they find they're not correct or missing when running?

    I guess the better thing is to use a 3rd party uninstaller like Revo or Ashampoo to help make sure everything is properly cleaned when uninstalling programs.

    I'll answer your last question with a quote from a post you just made:

    "I guess the better thing is to use a 3rd party uninstaller like Revo or Ashampoo to help make sure everything is properly cleaned when uninstalling programs."

    The question, and the topic, have multiple, multiple threads all over the forum. There is no right or wrong answer. There are as many opinions on the subject as there are members. The debate will go on and on. Everyone who would post an answer has a legitimate argument for or against doing it, and for and against any particular tool.

    I like your concept of the cleanest possible uninstall, that's about all I could and will recommend. I use Revo Pro.

    I have a lot of utilities that I manually update, most are all portable with examples of CPU-Z, GPU-z, Ccleaner, many system internals, etc.
    Now one way to maintain these w/o or a minimum of registry edits is when you setup the unpacked root folder for the utility, don't use xxx app name with a version # folder(example ccsetup558.zip). , use a generic folder name and exe name. This will save a lot of application paths in the reg over time. Now if your the type not to use a lot of exe's or reinstall OS then don't even bother with this.

    Thanks guys -- this is all very helpful.

    I've also started to get tired of Avast's outrageous claims on other things, like junk files. I do run CC Cleaner, but don't let it touch the registry. And where Avast claimed there was 22Gb of junk, CC Cleaner found 4Gb.

    I think what I'm going to do is with a new installation start using Revo Uninstaller.

    I'll also switch back to using Windows Defender. After some searching I see it has a very decent reputation and you don't get all the 3rd party sales nonsense.
    I swear by Revo Uninstaller. I have the paid version running on four systems in my home LAN.

    Q; What harm takes place if you never use a registry cleaner and never use a third-party uninstaller?
    A: Nothing.
