So Speccy removed that function and no longer reports that. But with many motherboards, the reported values were way off, reporting 6.2V for the 12V value as an illustrating example. For example, Speccy, their HW information applet, used to report PSU voltages as found on the motherboard. After upgrading from W7 to W10, or W10 to W11, once sure everything works, I will run the cleaner.Īnd for the record, Piriform also has a history of removing features that don't work correctly. So, for example, if I replace a NVIDIA graphics card with an AMD (or the other way around), I will run the cleaner after the installation to clean out all the crud left behind by the removed card.

One caveat/qualification - I never use the registry cleaner to 'fix' a broken computer - only to maintain it. And I never, not once had it brick a computer. While anecdotal, I personally have used CCleaner's Registry cleaner on 100s of different computers, likely more than a 1000s times. But still, many simply lump all Registry cleaners in one evil heap and that does CCleaners an injustice. In fact, if anything, some would suggest it is not aggressive enough. Yes, decades ago, some registry cleaner were reckless and way too aggressive. It is unreasonable to assume such a popular and useful tool that's been around that long would still be on the market (or, as an included feature) if that harmful as some suggest.

CCleaner has been around for close to 20 years. Having the ability to keep specific cookies during cleanup is invaluable to me.Īnd for the record, the claim that CCleaner's Registry cleaner can be harmful is misleading and totally exaggerated too. If you believe CCleaner is unsafe, then you should use no 3rd party cleaning tool and just stick with Windows own Disk Cleanup. Rather, it was caused by the new owners of Piriform (Avast) sticking their noses in the mix without doing their homework first. And it should be pointed out the issue that caused the most attention wasn't even caused by the developers of CCleaner (Piriform). And the problems were quickly addressed long ago. First and foremost, the few issues were minor, actually affected only a tiny number of the 10s of millions of users.
