Yes it is an admin user.

Yes I have read this, and it does not sound like the same issue I am having. This thread is from 2022, and it can't be the same CCleaner version as I am running This user's PC is running Win 11 Pro 64 bit, version 21H2, and my PC is running Windows 10 Home 64-bit 22H2 which is what came on it (never been upgraded) The CCleaner freeze on my PC never ends; I have left CCleaner open for hours, and it remains frozen until I end it with Task Manager My PC does not become unstable after ending CCleaner with Task Manager and continues to run just fine I don't see any resolution in that thread

I also uninstalled CCleaner with Revo Uninstaller Free, restarted the PC, reinstalled CCleaner Slim Build, and the problem persists. The GUI is still totally frozen.

I did not reinstall the Slim build but reinstalled the standard version from https://www.ccleaner.com/ccleaner/download/standard. What is the slim build? Does it have all the functionality of the standard version?

Yes, all three PC are running CCleaner 6.16, Windows 10 Home 22H2, and Trend Micro Maximum Security version 17.7.1951 with the latest updates. I have done the manual Trend updates. I have tried disabling Trend Micro to install, uninstall, reinstall, and run CCleaner all to no avail. I don't believe Trend Micro is the problem in this case.

Ok will do, thanks.

I have uninstalled, redownloaded, and reinstalled with same results. According to the link below, there is a command line /debug switch, but I have not tried that yet. I have tried these command line switches, and they do put me on the correct tab, but I cannot do anythning. The /cleaner switch still drops me on the Health Check screen because I haven't been able to change it to Custom Clean. /CLEANER (Opens Health Check or Custom Clean depending on which you have set as default) /REGISTRY /TOOLS /OPTIONS

I downloaded CCleaner at https://www.ccleaner.com/ccleaner/download/standard. I cannot access the GUI at all. There is no way to change the options. Yes I waited until it finished cleaning from running /auto from command line before trying to click the interface. It doesn't provide status while cleaning. The GUI is stuck just like the orignal screenshot. The icon in the system tray indicates it is cleaning, but I see nothing in the main GUI other than what I originally posted. I would like to get CCleaner installed and working on this PC. Is there any debug information I can provide?

I downloaded and installed the most recent version 6.16. This is the version that will not run. I did not previously have CClenaer installed on this PC. I am not running any other firewall. I did click the flashing tray icon while auto cleaning, and it did the exact same thing. It was frozen, and I could not click anywhere in the application.

Do you have any suggestions?

Running CCleaner64.exe /auto from the command line seems to work, but I can't do anything in the GUI, and I have no idea what has been cleaned if anything.

I can't click anything in the CCleaner window I posted. Yes, I can click on CCleaner in Task Manager and end task. I am running Windows 10 Home 22H2. Yes, I have rebooted. I have Trend Micro Maximum Security version 17.7.1951 installed disabling it does not resolve the issue. I have three other PCs running Trend Micro Maximum Security version 17.7.1951 and have no issue running CCleaner.

Again, I can't click anything on this window. I can't go to settings to change the home screen to custom clean. It is totally frozen. If there is a registry setting, I will be glad to try changing that to custom clean if you can provide the details.

CCleaner freezes on startup. I can't click anything. I have let it sit like this for 30 minutes or so, and nothing happens. I have run the Windows 10 disk cleanup utility. Any idea what is happening?
