10june2025 ccleaner free v 6.36.11508 64bit freezes after its finished doing a clean this has happened a few time in last week or 2 ..why ? I have to restart my win11 laptop because the ccleaner window covers most of my desktop icons so I cant click any of them, the ccleaner window goes a duller colour than usual but can not be closed
Is this about 5 seconds after doing a Custom Clean?
There is a current bug (its been happening for a month or more) where the CCleaner Free window will go grey for a second or two after a Custom Clean.
It is there for longer on some machines than others, but only for a second at most - nobody else has reported it freezing altogether.
When it freezes on you then how long are you giving it before restarting?
Rather than doing a full restart:
Can you not use the ‘X’ at the top-right of the CCleaner Window to close it?
If not, then in task manager can you right-click CCleaner and ‘end-task’.
i can not click the X at top right to close the screen when it goes wrong, it has happened tp me about 4 or 5 times in last week or so , it doesnt happen every time but as you can imagine it is extremely annoying as i have to restart my laptop or i cant do much. i always give it at least a minute or 2 before i realise its not trying to say pump out some annoying advert for some other ccleaner service
support on facebook or x told me to unistall it and reinstall so i did hoping i would get a slightly newer version when i reinstalled it but sadly i had the latest versrion so i have reinstalled the same flawed software, if it happens again i will try take a screenshot
i have tried task manager and that does not close it, also on other days when i have used ccleaner i want to fully close it to save on memory etc , but again windows11 will not let me end the task in task manager, ive also tried to kill ccleaner in process lasso software i use but again ccleaner or windows will not let us end ccleaner..why is that ?? i do not want it running all the time when i am not using it
If you are using any of these they will keep CCleaner running in the background:
- Options>Smart Cleaning.*
- Options>Updates>Keep CCleaner updated automatically.*
- Performance Optimiser - (If you have put anything to sleep).
*Those first 2 will also prompt Windows to put a CCleaner icon in the System Tray.
However Task Manager should be able to end the first 2 when told to, and PO does not normally show in Task Manager.
What does Task manager say, if anything, when it won’t let you End Task on CCleaner?
As you are the only one reporting this ‘freezing’ behaviour then can we ask:
You say that you have Windows 11, is that 24H2?
What Make/model is your computer?
Are you running any AntiVirus other than the built in Windows Security?
