The new CCleaner 7 is horrible

The new CCleaner 7 is horrible they have made it too complicated and reduced the functionality from the previous version.

As a long term user I will wait for my subscription to end and then find something else, it is a shame as it was a simple decent product.

Stole my money!
Somehow they managed to gain access to my paypal account for later transactions. They called it a one year support license, but with no intentions of renewing, they just went in thru Paypal and stole my money anyway. STAY AWAY!

There is no one to contact via email or phone. The only method is with AI and supposed human. Both are equally useless. I'm trying to reply to a customer support email and found out that the email is not monitored. I find the Chat feature and go in circles with AI/human who perform the same method of hanging up on customers. There is NO WAY to get help from CCleaner!

I used the newest version 7 to clean my pc, moved 2500 files (luckly to the trash) and it trashed several apps, slowed my pc, and many apps are slow to load. I undeleted the files, that helped but problems still exist. I have used CC for 20 years and found it reliable, the newest version needs refinement. I have now uninstalled it and I'm hoping I don't have to do a clean reinstall of windows.

CCleaner Beta destroyed my system — unbelievable negligence

I’ve been a paying CCleaner Professional user for years and never had serious issues — until I tried their new beta version.
It completely wrecked my system:
it disabled System Protection without warning,
it allowed uninstalling essential Windows components,
several apps (Slack, Notion, etc.) stopped working,

my external monitor stopped being detected, and I had to manually reinstall drivers and repair system files.
To make things worse, even though my license is active until 2027, their system now pretends I don’t have one.
This is unacceptable for a utility that claims to “optimize and protect” PCs. The beta build acts like malware — removing or disabling core parts of Windows without telling the user.
What used to be a solid tool has become a liability that breaks your computer.

I am writing to express my concern…

I am writing to express my concern regarding the complete lack of customer support. My credit card was charged for an annual subscription after I had canceled the service and received an email confirmation of the cancellation.

Despite multiple attempts to contact your support team, I have only received automated acknowledgments confirming that my messages were received. No substantive response or resolution has been provided.

Given this experience, I am deeply concerned about the company’s business practices and the lack of transparency regarding the entity responsible for managing this service.

ABSOLUTELY NO CUSTOMER SERVICE AT CCLEANR

I recently bought CCleaner app. Used it once. Then I got a notice from them about a "new & great" update to the app.
I tried it again & while it was doing a health check scan it got stuck at 90%. I went to try & get customer service and found out CCleaner HAS NO CUSTOMER SERVICE. No email, no phine #, no chat, NOTHING.
I finally figured out that Piniform is the place to go so I emailed them & they DID NOT HELP. They did not answer my question. They just sent me a "form email" referring me yto useless sights like Q&A. I anything goes wonky with CCleaner NO ONE WILL HELP YOU.

Love the service

Love the service. I've been using it since I was a kid, over a decade ago. Top tier ethics in business practices (incredibly uncommon these days) and does everything you need it to do for free. If you show appreciation with a subscription, they even simplify your life in many ways with some very much appreciated features.

They earnt my money just off the fact that they provide such a good service to everyone without discriminating against those who couldn't afford to pay (me as a kid). Bravo, keep up the amazing work! <3

Recurring system error with software…

Recurring system error with software update for security intelligence update for MS defender antivirus, which was reported to CCleaner and eventually escalated to specialist support - total lack of communication. Emails remain unanswered and the feedback email address is now not recognised. I have been a customer for several years and less than impressed with recent poor customer service.
Edit 15/10/25
CCleaner sent an mail asking for full information regarding the problem (previously provided). I responded to the email address provided and here is the response:

CCleaner BRICKED my system - Glorified Scripts with a UI

Title: BRICKED MY SYSTEM CCleaner's Duplicate Finder Wiped Out My Boot Camp Partition—Without a Single Restore Point Warning
Overall rating: 1 star
Review body:
I have been a CCleaner user for a while and even paid for the "Pro" version, but my recent experience was a complete nightmare. After using the duplicate file finder on my Windows Boot Camp partition, CCleaner identified and deleted what it claimed were "safe" files.
This was a catastrophic mistake. The program deleted critical system files, and now my entire Windows partition is corrupted. Worst of all, CCleaner performed this high-risk action without a single warning to create a system restore point or a backup. For any other software doing something this invasive, a backup warning is standard practice. For a company that markets its software as a system optimization tool, this lack of a safety net is completely negligent.
I have spent the last two and a half days trying to fix it, but Windows will no longer boot or reinstall correctly. The boot record is completely messed up.
For a supposedly professional tool, this is completely unacceptable. Deleting crucial system files is a fundamental failure of a cleaner's purpose. The duplicate finder feature is a joke and is written so poorly that it can't tell the difference between a harmless duplicate and a critical Windows boot file.
Save yourself the frustration and massive headache. Do not trust this software with anything important, especially if you are running Windows in a complex environment like Boot Camp. A system optimization tool should never be able to render a system unbootable due to such a basic flaw and without any prior warning. My mistake was trusting the software to have my back, but CCleaner proved it is nothing but a liability.

New CCleaner version 7 - DISAPPOINTING

The new CCleaner version 7 will not run properly on my Windows 11 computer. It loaded but when it opens the 'scan now' button shows, I click on it, but only a NON-INTERACTIVE window opens in a browser telling me about the new version. There is NO WAY to close this window and go back to the dashboard to scan my computer, so - only two stars for you. I have been using CCleaner for years and have always renewed my subscriptions, which are not due until 2026. I am VERY DISAPPOINTED in CCleaner's (Piriform) roll out of this new version. Right now, it is a TOTALLY USELESS app on my computer...!!
