I had meant using safe mode and then seeing if that partial bit of saved history was still there afterwards, or if it had changed in any way. As the partial history is not being saved when you use safe mode then that does tend to point to an app or extension that is keeping those last few histories for some reason. Even if it's one that you wouldn't expect to be saving history. To test that further I'd try disabling your addons/extensions one-by-one, a different one each time you use the browser - if the partial history is still saved then re-enable it in your next browser session and disable the next. It may take a while if you use a lot of extensions. (Maybe do a few at once to narrow them down in groups). If/when after disabling a certain one that history is no longer being saved then you have found the culprit. Of course one of the things about Chrome is that it can link with other Google/Alphabet apps, (such as your gmail). So it's also possible that it may be reading the partial history from one of those. CCleaner can only clear files from your machine, anything saved in the cloud such as synced data, or data stored by an account, can't be touched by any cleaning app. It's on a remote server and is protected from outside interference for your security. You can only ever delete such data from within the app/account that created it.

Thanks, It's very interesting that it isn't the entire history coming back but just the last eight sites. It appears that the Chrome history is in fact being cleared from the usual location, but that 'something' is storing a copy of those last eight somewhere else so they are not being cleared. Just what that 'something' might be, and why just the last 8, is another question. My first thought is that it may be an add-on or extension that is storing those last 8 somewhere? There are a number of addons for Chrome that manipulate browsing history, eg. https://www.makeuseof.com/chrome-extensions-organize-browsing-history/ Do you have anything that might do something like that? Or maybe a 'reload closed tabs' or similar addon. (I have one of those in Firefox that can restore any of the last 25 closed tabs, it doesn't survive cleaning though). You could try running Chrome in safe mode which disables all addons and extensions, if the sites you visit while in safe mode aren't saved in those 8 then it would point to an addon/extension. https://www.minitool.com/news/chrome-safe-mode.html EDIT- Another thought, are you signed into your Google account when using Chrome? What activity is that set to keep?

I have removed your email addresses for your security. It's not a good idea to put your current email in plain view, unless you want loads of spam. Send an email to support@ccleaner.com telling them you have changed your email address and giving them your old and new emails. They will change it for you.

Just to make sure of something here - because you haven't actually said and we have seen it before. You are ticking the boxes in Custom Clean - but are you then using Custom Clean or are you using Health Check? Helath Check takes no notice of what you have ticked or unticked for Cusom Clean, Health Check has set cleaning rules. If you are using Custom Clean then can you tell us what particular history it is that isn't being cleaned? I'm assuming that it's always the same things and that could give a clue what is happening, or not happening.

It should be cleaning the history. If it isn't doing that, and you don't have syncing enabled, then I'd suggest that the next thing to check is if your Chrome is continuing to run in the background after you close it. Background running of a browser can prevent things from being cleaned. Chrome, and Chromium based browsers including MS Edge, will run in the background by default, you have to change the browser settings to tell them not to. For how to prevent Chrome from running in the background see this: https://www.webnots.com/how-to-stop-google-chrome-from-running-in-background/

You should not be regularly using any Registry Cleaner on Windows 10 or 11 - Windows 10 and 11 change the registry too often for that to be safe to do. Yes, you might do it for years and get away with it, but eventually Windows can/will change something in the registry and that will catch you out - as you have found. For the official Piriform advice on using CCleaners' Registry Cleaner see this: https://community.ccleaner.com/topic/59952-i-get-a-registry-error-on-ccleaner-on-windows-10-i-have-scanned-5-times/?tab=comments#comment-326804 Registry Cleaning is now an advanced tool to help fix problems, it's not something that you should use regularly. It will not speed up your machine, or save more than a few KB of space. A registry cleaner is a tool that should only be used if you already have a problem that you are trying to fix. Even then it should be used carefully. If you wouldn't manually open the registry yourself and edit things in there then generally you should leave all registry cleaners alone. Here is Microsoft's stance on using any Registry Cleaner: https://support.microsoft.com/en-gb/help/2563254/microsoft-support-policy-for-the-use-of-registry-cleaning-utilities To answer your question of what CCleaner's registry backup is for: It saves the registry entries that it is going to change/remove (only those ones not the full registry) so that if something does go wrong you have a chance to 'merge' them back into the registry. It is only a chance though, sometimes the changes made mean that Windows will not let you merge it back, in which case it's probably going to mean you have to reinstall Windows.

Do you have your Chrome browser synced? CCleaner will clean your machine but if your browser is synced then the browser history will be put back from the cloud by the browser syncing - that's what syncing does. CCleaner cannot clear your account on the syncing server, for obvious reasons those servers are protected. Clear the Chrome syncing and turn it off. It tells you about that if you read all of that post I linked.

Have a look at this about why some things may come back straight after you have cleaned them:

Thanks again. I can see that - once a standard user has the necessary permissions they should then carry through an update. All my testing was done with 'clean' installs, ie. I had removed all traces of previous versions/installs before doing the next one. PS. It's probable that most people do run CCleaner from an install, (and/or run as an admin anyway), which is why the issue hadn't been reported previously. It also looks very similar in effect to an issue we often see with 3rd party AVs blocking CCleaner, so if someone did report it in less detail than you did yourself we would have probably assumed it was their AV that was blocking CCleaner.

You can download the Recuva installer from here: https://www.ccleaner.com/recuva/builds I have just this minute downloaded and installed it myself, so if you are still getting a 400 error then it's at your end or your ISP provider.

Thanks for reporting that, I hadn't got round to trying it. We'll have to wait and see what the devs come up with. TBH though as yours is the only report we have seen about this so far, and as there is a fairly easy workround, I suspect it may not be that high on their priority list.

It all depends what you think the word 'Tracker' is refering to, and in this case I suspect it isn't what you think. What Health Check is finding are simply cookies. There are many types of 'cookie', generally they fit into two main types - either an 'Authentication cookie' or a 'Tracking cookie' - and that is what Health Check is reporting it's found to clear. See here for a fuller explanation:

Ah, it's actually come from Invision which is the software that the forum runs on. It's a generic message from Invision refering to a feature that can be enabled on an Invision based forum, it's intended to get members to 'engage' more with a forum. But the 'Mark as Solution' feature isn't turned on here, so that message doesn't make sense for members here. Simply ignore/delete the email. As Nergal says one of the Invision technicians probably set/reset a messaging switch during a forum software update. One which isn't normally turned on for this particular forum. (Or possibly it could have been turned on deliberately by an admin here, but they forgot to also enable the 'Mark as Solution' feature that it refers to?)

Good to hear that it also works for you. It's obviously something to do with the extra 'getting things ready' (or words to that effect) that it does when you first open it following an install. As you have to have elevated permissions to install then I'm assuming you still have those elevated permissions when you run it from within the installer that first time. - That's one of the things that I want to check. I'm also not sure if the workround will survive across the non-admin user logging out and back in again? I think it will do but didn't test that. You might see that before I get round to trying it myself. TBH I should have tried that but I'd got tired of logging out and in again by that time.

Duplicate posts merged. This is a user forum and so it may take a while until a user with the relevant knowledge or experience of your issue logs in and sees your question. Please be patient. If you prefer you can raise a ticket with the official support team using the form here and selecting Recuva as the product: https://support.piriform.com/hc/en-us/requests/new?ticket_form_id=86507 Or you can send an email to support@ccleaner.com

That particular feature is not enabled on this forum. (Unless someone on the staff has recently enabled it, and I don't think so). Admins and Moderators can/do change the title of a thread to show it's been solved, and we can 'Recommend' a particularly helpful post in a thread to bring it to the attention of others reading. But neither one of those is something that we do often, usually only for 'hot topics' at a particular time. Are you sure that the email came from here and not from some other forum? It doesn't sound like the sort of thing you'd get from here. I'd check the email header/source to see just where it cane from.

Was this a 'cashback' offer? If so then there should be a 'How to claim your cashback' link in your purchase confirmation email. Here is the 'How it Works" page which also includes a link to the online application/claim form: https://www.ccleaner.com/ccleaner/cashback/how For the cashback offer that was run between 19th and 26th October you have until midnight on the 26th November to claim your cashback. https://www.ccleaner.com/ccleaner/cashback/terms-and-conditions

Thanks for replying @SimonFastEddy It could well be Windows Update that removed/is removing the restore points. It will always remove restore points now if it's a change to the Windows version, eg. 21H1 to 21H2. It may also remove them during 'lessser' Windows updates, Patch Tuesday, etc. That's because some Windows users would attempt to use a restore point to 'roll back' following a Windows update. In some cases that couldn't work because Windows had changed too much during the update, and trying to do it could mess things up irretrivably meaning Windows then had to be fully reinstalled from scratch. So to prevent it even being tried MS simply remove previous restore points during some Windows updates now. I'm not sure if they only remove incompatible RPs, or just clear the lot which would be easier to do. (If you do want to roll back from an update then you have to do it by uninstalling the update through Windows Update>Update History). PS. The current CCleaner version is now v6.05

I've tried it now on 22H2 and got some interesting results, and a possible workround for you. I can reliably replicate what you are seeing, and I can get round it quite easily. The testing I did: I created a new standard user and installed CCleaner Free from that user account (admin password req'd of course). I didn't open it from the installer when it asked. After installation CCleaner wouldn't open. Uninstalled (and cleaned up using Revo). Installed CCleaner again as the standard user, (admin password req'd), but this time I opened it as the last step when the installer asked. It opened from the installer and ran normally, I closed CCleaner. It would then open as normal for the standard user from the desktop icon, and also from the exe in File Explorer. Uninstalled (and cleaned up using Revo). To test it a bit more: I signed out of the standard account, logged back in as Admin and installed CCleaner from there, I didn't run it from the installer. Logged out, and back into the standard account. CCleaner would not open for the standard user. Back to the Admin account, (and a quick double check that CCleaner ran there as normal, it did). Uninstalled (and cleaned up using Revo). Installed from the admin account again but this time I ran CCleaner from the installer when it asked. Logged out and back into the standard account. CCleaner would open from the desktop and from File Explorer as normal for the standard user. So the solution appears to be that if you want a standard user to be able to use CCleaner then you now have to run it from the installer first time when installing. If you don't do that then it won't run for a non-admin user. I've not tried to replicate it again on 21H2 but I assume it will be the same. It appears that running CCleaner initially from within the installer is setting something 'extra' that doesn't get set if you don't run it that one time from the installer. (And of course you always have admin permissions to use the installer, so also for that first run of CCleaner from it). Why it should be doing that I have no idea, from your own observations it must be tied to the folder permissions somehow. I'll point it to the staff for the attention of the developers. Of course an easy fix would seem to be having it always run from the installer rather than giving the option not to. Many other software installers do that as standard and alway open the newly installed app. Please let us know if runing CCleaner initially from the installer, also cures the issue for you like it does for me. (I've thought of another couple of things to try/test later, but that's more for my own interest and shouldn't add much to the above if anything).

If you are sure that it's a HDD then it will be fine to defrag it. (TBH defragging shouldn't harm a modern SSD either, but it won't realy do anything other than use up some of its write cycles unecessarily. Modern SSDs have many more write cycles that the early ones did).

Thanks for all that. Knew I shouldn't have deleted the non-admin account yet, LOL. I'll set one up again and install CCleaner free on it and see what I can from there. I'll probably do it on the 22H2 machine but that won't be until tomorrow now, I'm currently on my second pint in the pub. Just to note that it doesn't matter if it's the slim or standard installer, both install the same CCleaner. I was previously aware of the permission changes to the CCleaner folder, and had asked the staff about it because I sometimes want to manually edit files in there as part of testing things. I wasn't aware of it causing any problems with running CCleaner itself though, so if it is then it should be fixed even if it's only affecting a few people. Of course it may be a 22H2 problem, but you say it was the same on 21H2 so maybe not. Just another question- which antivirus are you using if not just Windows? If it's a 3rd party AV then what version is it at?.

First results. I created a non-admin user account on my 21H2 machine and logged into it. As you can see from this screenshot CCleaner v6.05 ran and cleaned sucessfully. Both Health Check and Custom Clean worked as normal. To show it's a standard account it wouldn't run the Perfomance Optimiser, that's as expected because you need to be an Admin to do that. I'll try the same on a 22H2 machine later. PS. After doing the above I deliberately created some more Junk, ran Edge, etc, in the standard account. Switching back to the Admin account and running CCleaner from there with 'All users' selected cleaned the standard account as it should.

The change of access rights for the CCleaner folder(s) affects Admin accounts also, but maybe not to the same extent as a non-admin account. I believe that it was done as a security measure. I wasn't aware though that it could affect the normal running of CCleaner in a non-admin account, that hasn't been reported before. I note that you have the recent upgrade to 22H2 so am wondering if that may have something to do with it. Could you run from the user account when you had your previous Windows version? I assume that you are installing CCleaner in the Admin account? If you have a CCleaner Pro licence you can clean other user accounts from an Admin account. (or at least you should be able to). I'll have a play (do some testing) later when I get time, I'll need to set up one or more non-admin accounts on this machine. If I don't find anything on this 21H2 machine I do have another laptop with 22H2, so may have to do things twice.

Simply move your cursor slowly up and down across the line below it and when the cursor turns to a double up/down arrow click and hold your mouse button then drag the window to the size you want it to be. Once you have the size you want showing then do the same again only this time at the line above it to move the whole drive map up or down the page. The panes above with the drives, and below with the Status, will resize themselves to suit where you position it.
