While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more

To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more

Now unfit for purpose after major…

With vr.7 this is now unfit for purpose. What the hell have the geeks done to CCleaner? IT'S NOW AWFUL. SLOW, SLOW, SLOW. UI is appalling. A major update to UI et cetera has made this absolutely terrible in ALL aspects. It now takes three/four minutes to even load up program. REALLY? It now takes over TEN MINS to scan. REALLY? POOR. VERY POOR. Before update vr.6 took seconds to load program and also under two minutes for a full scan. Absolutely ruined it geeks. What a way to torch a program. FFS!!

Windows update error 0x800f0991 solved

Error 0x800f0991 (Windows update KB5079473) solved!
I tried to install it three times in different ways, but it didn't work. My computer also slowed down. Then I called CCleaner for help, and the installation was successful! My computer works fine.

Gone backwards

Well, it used to be good. But ever since the 'upgrade' it's just not as good, nor as intuitive. I use other cleaners now.
