Free Download Ccleaner Latest Version For Windows 10
Anna Pybus
I run Windows 10 Pro, 64-bit, on an original installation by Dell on a new Precision 5810. I have repeatedly installed and uninstalled CCleaner 5.562.10 (free version), but it always installs as a Windows 7 64-bit version, and although the registry cleaner can read the registry errors, it cannot correct them. I would have no problem paying for the CCleaner Pro version if this would be certain to solve the incorrect-Windows-version / registry cleaner problem, but if it won't, I'd rather just find another program. I've always liked CCleaner, though, and would prefer it if anyone knows how to get it to correctly read that this is a Win 10 computer. (The only Win 7 compatible programs I run are Adobe CS 6 ones, and I have tried removing all Adobe files from the Windows 10 startup, then rebooting, then reinstalling CCleaner, but that didn't make any difference.) Any ideas?
perhaps w10 pro was an upgrade as on many other pcs (dell has it done for you) ccleaner cant scan the correct os and anything go wrong, maybe the mods or developers can tell an answer
Thanks so much for taking time to comment. Trium, that PDF is for the same Dell Precision 5810 tower I have; mine has a RAID1 so there are a few minor differences from the standard model. MTA, here is a gif and a pdf screenshot showing my Win10 build and the CCleaner version. Any suggestions for resolving this issue are much appreciated.
Hello, I've been using CCleaner professional on my PC and laptop for quite a while now. Recently, microsoft did one of their forced updates on my laptop, and now I cannot get CCleaner to open. (windows 10)
Also what Windows 10 version do you have now, and what AV are you using?
As you just got a forced update you will previously have had Windows 10 1903, that became 'end of life' on 8th December so they are now forcing updates to it.
Which version you have been updated to will depend on your computer.
Seeing as CCleaner stopped working for you following a Windows Update there is something that you should check.
Check Windows settings for Apps & features to make sure it hasn't defaulted to only allow apps from the Microsoft Store, it has been known to do that after a Windows Update.
If it has then change it back to 'Anywhere'.
The latest CCleaner version is 5.88, if you don't have it already then you can download the installer from here and simply install it on top of your current version, ie. no need to uninstall first.
If you are still having issues after doing that then would be the time to try uninstalling CCleaner and doing a fresh install.
If you do uninstall then make a note of your registered name and licence key before uninstalling, you'll need it to re-register the new install.
PS. AV is just shorthand for AntiVirus, Windows Defender is the standard one that all Windows 10 has and is very good - some people do like to use a different one though which can sometimes cause problems.
Norton is good. (In fact they now own Piriform/CCleaner since they bough Avast).
Microsoft Defender is now also fine, it ranks as good in tests as most that you can buy and better than many, and as it's already included with Windows why pay for something else?
If you don't put another AV on your machine, or uninstall an AV that is there, Defender will take over automatically.
Microsoft Defender isn't as feature-packed as the top antivirus competition, but it's more accurate than some big-name commercial products, and is much less likely to cause issues with your other applications. If simplicity (or price) is top of your priority list, it's a reasonable choice.
There has been quite a bit of press coverage today about our announcement that the Piriform CCleaner product was illegally modified during the build process to include a backdoor component. Our first priority is our commitment to the safety and security of our millions of users, and supporting our new partner Piriform as they manage this situation. We understand that given the late disclosure of the massive Equifax data breach 10 days ago, consumers and media are very sensitive, as they should be. As such, as soon as we became aware of this issue, we engaged and solved it. Within approximately 72 hours of discovery, the issue was resolved by Avast with no known harm to our Piriform customers. The purpose of this article is to clarify what actually happened, correct some misleading information that is currently circulating, recap what actions Avast took, and outline next steps.
Shortly after the original announcement, a series of press stories were released but many of the details about what happened and the impact on users were surmised. We would like to take this opportunity to correct as much as we can in this article.
Many of the articles implied that 2 billion users were affected with an additional 5 million every week. This comes from the fact that since CCleaner started, it has been downloaded 2 billion times with 5 million a week being currently downloaded, as presented on their website. However, this is several orders of magnitude different from the actual affected users. As only two smaller distribution products (the 32 bit and cloud versions, Windows only) were compromised, the actual number of users affected by this incident was 2.27M. And due to the proactive approach to update as many users as possible, we are now down to 730,000 users still using the affected version (5.33.6162). These users should upgrade even though they are not at risk as the malware has been disabled on the server side.
Avast first learned about the possible malware on September 12, 8:35 AM PT from a company called Morphisec which notified us about their initial findings. We believe that Morphisec also notified Cisco. We thank Morphisec and we owe a special debt to their clever people who identified the threat and allowed us to go about the business of mitigating it. Following the receipt of this notification, we launched an investigation immediately, and by the time the Cisco message was received (September 14, 7:25AM PT), we had already thoroughly analyzed the threat, assessed its risk level and in parallel worked with law enforcement in the US to properly investigate the root cause of the issue.
Following that, the offending CnC server was taken down on September 15, 9:50 AM PT, following Avast collaboration with law enforcement. During that time, the Cisco Talos team, who has been working on this issue in parallel, registered the secondary DGA domains before we had the chance to. With these two actions, the server was taken down and the threat was effectively eliminated as the attacker lost the ability to deliver the payload.
Some media reports suggest that the affected systems needed to be restored to a pre-August 15th state or reinstalled/rebuilt. We do not believe this is necessary. About 30% of CCleaner users also run Avast security software, which enables us to analyze behavioral, traffic and file/registry data from those machines. Based on the analysis of this data, we believe that the second stage payload never activated, i.e. the only malicious code present on customer machines was the one embedded in the ccleaner.exe binary. Therefore, we consider restoring the affected machines to the pre-August 15 state unnecessary. By similar logic, security companies are not usually advising customers to reformat their machines after a remote code execution vulnerability is identified on their computer.
Customers are advised to update to the latest version of CCleaner, which will remove the backdoor code from their systems. As of now, CCleaner 5.33 users are receiving a notification advising them to perform the update.
We plan to be issuing more updates on this as we go. We have made it our highest priority to properly investigate this unfortunate incident and to take all possible measures to ensure that it never happens again.
The changelog of the new release highlights the change in euphemistic terms: "Added more detailed reporting for bug fixes and product improvements". The company added privacy options to CCleaner in May and stated back then that it collected only anonymous data from free users and did not display the options to free users because of that.
CCleaner users who run the new release may notice two changes immediately: It is nearly impossible to disable the monitoring part of CCleaner (Active Monitoring), and there are not any privacy settings anymore in the free version of the program.
Note that you can't close CCleaner anymore using interface controls; A click on the x-icon minimizes the program, and the right-click system tray icon displays no option to terminate the program. The only option that is available is to terminate CCleaner forcefully.
Piriform addressed user concerns in a post on the official forum. A Piriform admin confirmed in the post that the company extended the analytics functionality of the software "in order to gain greater insight into how our users interact with the software".
Piriform states that the data is completely anonymous, and that it uses the data to "rapidly detect bugs, identify pain points in the UI design, and also understand which areas of functionality [the company] should focus [...] time on".
The company reiterated in the post that it does not collect personally identifiable information about free users but failed to disclose what data it collects and how it stores, shares, and processes the data.
The company promises to do better by separating Active Monitoring and the anonymous collecting of usage analytics in the user interface so that users can (better) control the two features. Users will have options to enable none, some or all of the functions directly from the user interface.
The new release is weeks away according to the post and users who upgrade to version 5.45 are stuck with a program that runs constantly in the background and reports analytics data back to Piriform. Most users may not be tech savvy enough to disable the monitoring component (and thus the sending of analytics data).
