CCleaner very slow startup time on my Windows 10 Pro x64 DELL laptop.

Hello @Melchior,

It could possibly be to do with the settings. Maybe when you updated CCleaner, it reversed to default some of the settings that you had previously changed.

When I set mine up many years ago, I made a note of ALL the settings once I have finished amending them, along with screenshots, so as I could always check them against the current .ini / .cfg file. I did remove some of the CookiesToSave from the .ini file.

If you did something similar, then perhaps you could check to see if that is the case for you.

Just a thought.

I hope this helps.

hmm.. probably not I store the settings in an .ini file per settings...
I checked ... settings seem fine..

Nothing that I know of that would effect the CCleaner startup time...

OK, it was just a thought.

My CCleaner 5.78 takes 8 seconds to start. I just... deal with it.
It's not like I have to start it more than once or twice a day.

It may be CCleaner fighting with my Firewall?
These items are all blocked...

Mine is NOT lightening fast either, which doesn't bother me, but there again, I am on a 12 year old Laptop.

I execute CCleaner from within my Disk Cleanup Batch Script that I wrote, and I have Scripted a full 60 seconds for it to complete before it moves on to the next command. I just run the Batch Script once a week, or whenever I feel like it.

@Ghot

Add these to your hosts file.

Latest CCleaner Version Released

Note: Changes to hosts file may not take effect until internet is disconnected then re-connected.

EDIT: Also if you are using winapp2.ini then you might need to trim it.

@Melchior

Try a clean install of the program. Uninstall it and reboot then if found delete:

C:\Program Files\CCleaner

Then download and install a fresh copy.

Good call. I added these...

Delay is gone.

Panda power... to the rescue.


For anyone else... the HOSTS file is here...
C:\Windows\System32\drivers\etc

Right click the HOSTS file choose: Properties and UNcheck the Read Only box.
Open the HOSTS file with Notepad.
Copy/paste those lines at the top, UNDER the last # sign.
Choose File > Save ...at the top
Close Notepad and then right click HOSTS, choose: Properties and REcheck the Read Only box.

The hosts file advice was for Ghot. It was not intended for you. I only suggested that you try a clean install of Ccleaner but you might make a backup copy of the settings .ini file first. I've had issues in the past a few times where a clean install of the program fixed it.
