Windows 10: Ccleaner safe or will it cause more issues?

I have a couple of questions, first is Ccleaner okay to use? Also whats a safe site to download it from? I’ve uninstalled Microsoft Flight Simulator Stream and reinstalled it but at times it will freeze up when switching from one aircraft to another. I want to uninstall the addons and then uninstall Flight Simulator and run a registry cleaner/repair. Restart my pc then reinstall Flight Simulator. thanks, Blair...

CCleaner Safe?

I love to use CCleaner to remove temporary files and cookies but is the registry cleaner acctually safe to use? Would I be best off avoiding using it?

Depends...

Piriform (the maker of CCleaner etc) was bought by Avast in July 2017 and there was this nasty incident...

• https://blog.avast.com/update-to-the-ccleaner-5.33.6162-security-incident

All CCleaner versions are bundling Avast AV and/or various Google products such as Google Chrome, a Google toolbar and possibly other products....

Microsoft Community has seen quite a few of related threads.

Recently more and more threads are popping up in the Piriform/CCleaner forum which hint at even more questionable methods...

Here are a few recent example threads:

IMO, CCleaner is not unproblematic and has to be treated carefully.

I, personally, would not recommend CCleaner to inexperienced and/or not so tech-savvy persons...

Suggestion to inform yourself before installing CCleaner (or any other product) and to always, always keep your eyes wide open during installation (watch out for any bundled softwares etc etc).

WRT to CCleaner on Windows 10:

According to
this post Windows 10 blocks older versions: "CC v5.27 and older, (or somewhere around there) are no longer deemed safe by MS and automatically blocked when starting."

Is CCleaner safe to use?

While CCleaner is safe and useful for removing unused, temporary, junk and privacy related files (cache and cookies) for Internet Explorer, Firefox, Thunderbird, Chrome, Opera, Microsoft Edge, I
do not recommend using the built-in registry cleaner unless you have a good understanding of the registry. However, CCleaner's registry feature is and requires a separate user action from the Cleaner so it cannot be used at the same
time.

Be sure to read Microsoft's support policy for the use of registry cleaning utilities in that topic...Microsoft does not support the use of registry cleaners.
