Can anyone shed any light on this? One thing I definitely want to avoid is browser history deletion, as I use browser history frequently - especially in Firefox.īTW, before anyone suggests that I can fully avoid CCleaner by using other tools such as Windows Disk Cleanup, please note that I rarely use CCleaner to do any deletions or other tasks besides these: (1) simple deletion of all cookies that I haven’t pre-designated as “keep” (all browsers) (2) simple deletion of browser cache (all browsers) and (3) importantly, pre-defined custom file deletions on a few folders per my designated deletion schedule. I don’t recall the details, but I think it was related to unintended file deletions from certain folder(s). 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.

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.
