My question before installing this version of CCleaner on the new computer: I recall seeing a warning awhile back that this-vintage version of CCleaner was not fully compatible with Windows 10. I have long been using Piriform CCleaner version (installed, not portable), which was the last (or at least one of the last) versions released before Piriform’s acquisition by Avast (and the issues that followed it). Until now, I have stuck with Windows 7 Pro 64-bit (and ESU updates) on my Lenovo laptop, but in December or January will be moving to Win 10 64-bit Pro on a new Lenovo. This is especially the case when that latest version of CCleaner has data collection options enabled by default (see the section below).I see that there has already been recent discussion/mentions of CCleaner, but it doesn’t zero in on my particular compatibility question, hence this post. It's a bit ironic to claim that going into a user's system without their permission and making changes is a move based on privacy and transparency. 'Since the release of v5.46 we have updated some users to this version to meet legal requirements and give users more autonomy and transparency over their privacy settings.'

As it turned out, that's exactly what happened.Ī Piriform staff member responded with the following: A user on Piriform's forums noticed that CCleaner had automatically updated on his system without his permission. The latest CCleaner controversy comes from ignoring user preferences about checking for updates. In our opinion, it isn't time to trust CCleaner. This is unfortunately not surprising after Avast purchased CCleaner developer Piriform in July 2017. Why Is CCleaner No Longer Safe?ĬCleaner, once a tidy app with no history of issues, has had several major problems in less than a year.

Here's why you can't trust CCleaner anymore, and what to replace it with.
