Well, Crap. I don't know whether to thank hazelnut or curse her. Here is all the Operating system info, although it is irrelevant at this point. When I created a new user account and switched to it, the problem went away. That means that I have to delete my original account and make ALL the changes to the new account to make it look and operate the way I want. Crap!!! Too much work!!! Anyway I will be able to continue to use CCleaner with my computer operating the way I want Edition: Windows 10 Home Version: 20H2 Installed On: 2/‎18/‎2021 OS Build: 19042.1466 Experience: Windows Feature Experience Pack 120.2212.3920.0 Thanks for everyone's Help with this.

I also want to point out that a problem is never reported until the first person reports it.

I can see where there could be a conflict between a setting on my computer and the running of CCleaner it seems obvious that there is. But, the way I see it the Microsoft settings are working and the third party CCleaner software is somehow messing up the inactivity timer or blocking the trigger that turns on the screensaver after the inactivity timer counts 3 minutes. What in the running of CCleaner could do that regardless of all these configuration changes that have been tried so far.

Hazelnut, As I posted before I am using the blank screen screensaver. I have not upgraded since the Free Microsoft upgrade to WIN 10 several years ago. I am the only user of this computer and have admin rights assigned to the user account. If there IS a problem with ANY setting I have made on the computer, I would like someone to explain to me why the screensaver works consistently ALL the time, WHENEVER I use the computer, the activity timer ALWAYS turns on the blank screensaver as long as I DO NOT use CCleaner.

Well, I am running a custom clean and not health check, and no, I have not run registry cleaner in months. Since my last post I uninstalled CCleaner, changed my power settings to balanced and windows default settings and then reinstalled CCleaner with default settings. I rebooted and waited to see if the activity timer would start my screen saver at the 3 minute mark and it did. I then ran a custom clean with CCleaner at it's default settings and waited for my screen saver to come on and it never did. I don't understand why the screensaver activity timer would be changed by running a custom clean with CCleaner either, but it seems that it does.

Not using third party software to manage my power settings. But, I tried adding the temp folder to CCleaners exclude list. It did not make a difference as I suspected. If that was the problem, it seems to me that when I unchecked every single box in CCcleaner it would not clean anything including temp folders and files. I am curious as to why you seem so reluctant to conclude that it is CCleaner that is causing the problem. If I do not use CCleaner, the screen saver comes on after 3 minutes of inactivity as it is set for and is supposed to do. Only if and when I run CCleaner does the screen saver not time out due to inactivity. If it was one of the check boxes in CCleaner that I had checked that was the problem, then I would think that when I unchecked ALL the boxes, the screen saver would have timed out due to inactivity after running CCleaner with NO boxes checked. I can only conclude based on this evidence that there is a conflict between CCleaner and the screen saver/power settings that I am using. The only options I see left is to either stop using CCleaner, reset the Screensaver every time after using CCleaner or to try going to another configuration in my power settings, but since I don't really want to change my power settings, I guess that I will have to decide if I want to continue using CCleaner, to try some other cleaner.

When I said that I had restored the default settings I meant that I had clicked on the button that says restore default options for this plan. I just checked and all settings have remained the same as I had set them. As for the hard disk setting, there is a never setting, so it seem stupid to have 0 do the same thing, but whatever. Anyway I have it set to not shut off for over a week, so that should not be an issue. As for the hibernate setting, are you saying that the advanced settings box does not really set it? Also, If it is a power setting causing the problem and not CCleaner, why does the screen timeout setting continue to work as long as I do not run CCleaner?

Thanks again for trying to help with this. I had already done what you suggested, however I went back into my power settings and restored the defaults to the high performance plan as you suggested. I then went back into the advanced settings and changed everything to never shut off which is what I want, even though Microsoft does not want that. It kept changing the disk shutdown to 0 minutes from the never that I had set, so I changed the time to over 10K minutes. It also did not like that I changed the hibernate sleep setting to never but eventually took it. When I was finished I closed everything, restarted the computer and went back to make sure nothing changed. I waited for 3 minutes and the screensaver setting kicked in and the screen went blank. I then ran CCleaner and the screensaver never timed out. Again, there seems to me to be a bug in the CCleaner software.

Thanks for replying. I was aware that Windows keeps breaking my power settings with their updates. However, this seems to be specific to running CCleaner. Each and every time I run CCleaner if I want the screen saver to work I have to go to that specific setting and hit the ok button or the screen will never time out. I have tried unchecking all the boxes on CCleaner and still have the problem. I am thinking now that it is a bug in the CCleaner software.

Whenever I run CCleaner, it breaks my screen timeout setting. I don't know if this is because of any changes I made to the settings in CCleaner or if it is a default setting. There ate 2 ways that I have discovered to fix this. One is to go back to the screensaver setting, which I have set to a blank screen and 3 minute timeout, and click on the ok button. then 3 minutes later it will go to a blank screen. the other way is of course to restart the computer. So, it seem to me that CCleaner is cleaning something that is involved in this setting. Is there some setting in CCleaner that I can change to fix this?
