Love this product easy to use and keeps my pc in great working condition.
CC7 uninstallable
Installed CC7. Should have stuck with 6. At conclusion of installation, "start your first scan" flashes by, to be replaced with another screen extolling how CC7 does everything except walk the dog. Only way to escape that screen is to close it manually, thus starting the process all over again. My money is better spent elsewhere.

The new CCleaner 7 version has no way to turn it off; there is no way to exit it completely, it remains in the taskbar, and if I right-click it, there's no way to exit.
It also uninstalled Brave and Chrome without me asking it to do it, or at least it made all the shortcuts unusable; I had to reinstall Brave and Chrome. Wonder what else it has done.

Beware of CCleaner Billing
CCleaner is excellent and valuable software but the billing via Cleverbridge is a disaster and essentially a fraud. I have an invoice and payment statement indicating I have a 12-month license beginning Mar 18, 2025 but my account with CCleaner shows an expiry date of Dec 22, 2025. So I received 3/4 of a year subscription while paying for the full year. CCleaner's website provides no assistance in addressing my billing issues and no contact e-mail address is provided. It would appear that the company has no interest in providing support.
poor way of confronting with great news
new release / update? what a bad experience.
nothing works anymore, very poor . i am very loyal so i do not give up easy, but......i am getting sick of restarting my laptop every time i try to use ccleaner.'
it blocks my startscreen for 99% and makes things unworkable. client for more then 10 years .Heeeeeeeeeeeeeeelp

I have had the product for years but consider to stop
I have had the product for years and it works fine for me. However, when I accepted an offer for renewal 3 month before it runs out the 3 months was cut off. Trying to contact CCleaner about it is one of my worst experiences. No answer. Trying again - No answer. Have asked for a refund - no answer.

I have used C Cleaner for years and have been happy with their service. They keep my computer clear of lots of dross I accrue and keep my drivers up to date. I had a problem a year ago and had no trouble contacting the company and my issue was sorted in no time.

it brought up my videos back again by their app Recuva
I used their Recuva and it is legit! It didn't get me any virus, it brought up my videos back again!
The product installed "CCleaner"7 on its own and it doesn't work
The product installed a "CCleaner 7" BY ITSELF, and now it doesn't start. I uninstalled and reinstalled it - nothing. What is going on? This is becoming unacceptable, after acting like malware and freezing/crashing my PC now it does this and won't even start.

Do NOT lose your license key
Do NOT lose your license key. I reformatted my system and didn't take note of the key. Emailed support with my information... TWICE. Was ignored.
Can't support a like that.

Very good value for what it does well

Shocking customer service
Shocking customer service.
No longer using the PC I had installed the software. Then receive an email mentioning auto renewal about to take place. But the price has QUADRUPLED which is a huge shock.
Attempt to contact them through the support site and get into a circle of ignored requests/ acknowledgment emails none of which can be replied to.
Every single email attempting to contact the company is from non-monitored email addresses each reply just states we received an email but your email will not be looked at as not monitored etc.
attempting to stop the renewal amount which is taken on my credit card and could not be prevented.
Very very very suspicious.
This was a half decent bit of software in the past. But now the lack of support and literal THEFT from your bank or credit card is shocking.
The company cannot be trusted.
The renewal process is a scam if you do not have access to the programme on your pc any longer I’m not sure of how to ‘cancel’ the subscription other than clicking the links in their emails and filling the forms that are all ignored.
Monies taken and dispute raised with credit card company to get the money refunded.
A once trusted company now utterly corrupt and utterly lack any form of customer service.
When you cannot email or phone a company to raise a query or dispute you know you are dealing with people that want to hide behind a smoke screen
BEWARE PURCHASING IF YOU DONT WANT INCREASED PAYMENTS TAKEN WITHOUT THE ABILITY TO STOP OR CANCEL AND REFUND.

I have tried almost all of the utility software on the market and CCleaner by far is the best! Two of the main important features besides keeping the computer running at its maximum, is the fact it includes software and driver updates in the program! None of the other competition offered these features!
