NOTE: Recent press about CCleaner indicates it may represent a privacy concern.

CCleaner is a feature-rich system optimization and privacy tool. The program cleans unused, temporary and log files from your system, as well as traces of online activities such as Internet history and flash cookies. The program contains startup controls for Windows, major internet browsers and context menu entries. Includes a separate registry cleaner, duplicate search, system restore tool and can wipe both deleted files and drive free space for security.

A 64-bit version is available (within the folder). Monitoring functions are only available in the pro version.

Additional cleaner rules can be using an unofficial set of community-developed set. It should be noted that many of these rules are alpha and the developers will not provide support for these rules, a thread in the users forum is dedicated to supporting the add-on rules.

Alternatively, ccPortable is also available.

CCleaner is a GREAT utility, but still has one serious flaw. After all this time, it STILL does not wipe file NAMES along with file content.

AMITZ 2007-10-02 12:58

Yep, still no filename wiping. Is this because it supports all flavors of Windoze? How about an XP only version?

Still One Problem Remaining . . . 2007-11-11 09:01

CCleaner now wipes file names, but unfortunately it does not wipe files in the Recycle Bin. I deleted a file to the recycle bin, ran CCleaner and was able to recover the file and it was 'good as new.' CCleaner does seem to wipe files from folders, as it should. Other than this 'serious flaw', CCleaner is one fantastic utility.

a 2007-11-13 08:44

execellant file cleaning, been using it since it first came out, you can make it even smaller in size by deleting all the lang-xxxx.dll files that is if you only need english (looses about 678 kb's.), otherwise might wanna look into language codes and keep the one you need if still you want to decrease the size.

a 2007-11-13 08:47

can also delete unicows.dll, if you know you wont be using any windows older than xp. so its around 815 kbs vs. 1.71 mbs

Shodan 2007-11-27 06:03

The latest release of CCleaner - 2.03.532 - seems to have corrected the Recycle Bin wiping issue that was in previous versions running on Vista. If you have not tried this little gem, you are really missing something. Especially if you have enough computer knowledge to edit the winapp2.ini file and make it to what YOU want it to. THANKS for a fantastic tool ! ! !

j_sk 2007-11-29 08:10

I've been using CCleaner once a week for almost one year, I'm on Vista Premium since 9 monthes, and it has always wiped filenames and recycle bin.
I mean, no problem.

iVo 2008-01-17 05:01

Cool app. Just pack the *.exe and *.dll files with upx or other exe packer to save some space. :)

bjv16 2008-01-20 13:12

When it is used portably and set to save settings to an ini file, it will delete the registry keys of any version that is installed on the computer running it, if it is installed.

Shodan 2008-03-29 10:59

Sorry, I erred on my last comment. Prior to the latest releases, CCleaner failed to delete the index.dat file on Vista at bootup - not the Recycle Bin. As j_sk wrote, it has always worked on the Recycle Bin. Now the index.dat file is also erased beyond recovery at bootup.

ravinder 2008-04-01 19:20

CCleaner is a GREAT utility, but still has one serious flaw. After all this time, it STILL does not wipe file NAMES along with file content.

Neyon 2008-07-29 09:23

By far the best cleaner. Never had any problem!!!

Mike 2009-08-20 18:06

Great program. I've been using it for years and have had no problems. I strongly recommend it.

Mark 2010-01-27 12:47

Good portable, but which of the lang files (which isn't English) can be deleted? The language files are all labelled 'lang-1025.dll, lang-1026.dll' etc. Could save 900 KB by removing the unused ones. Cheers.

Billy Bob 2010-01-28 19:50

Delete the whole lang directory and you will have English, and remove all the other languages

Mark 2010-04-27 00:29

Is it just me or does CCleaner not compress under upx anymore, I used to do it but can't now.

Does anyone know a way round this.

joeytrippin 2010-08-26 14:27

Just installed the newest version of the ccleaner (v2.35.1219) and now I cannot uninstall programs? Any clues what the problem is? (I have restarted the computer)

Paul Regan 2010-09-02 21:04

Your portable version does not appear to plug into the Portable Apps application, which is looking for a *.paf.exe file. Could you please go the last mile and make this great app truely portable?

webfork 2010-09-02 22:18

Paul: you will need to contact the developers of CCleaner or PortableApps about converting the program to a PAF-compatible format.

ArnaudNime 2010-09-23 18:28

Take care ! CCleaner doesn't work any more after compression with upx2.0.7

yorap 2010-09-25 15:56

same here
CCleaner doesn't work any more after compression with upx2.0.7
CCleaner introduced TLS callbacks

Wizzer at Colour4Free 2011-01-14 12:21

I have tried out UPX compression on all portable versions since 2.27. None of them run after compression. Version 2.27 is the last that can be UPX compressed and still run. You can find it on the site

freakazoid 2011-01-31 05:09

To save space delete the x64 version and delete the /lang/ folder (if your first language is English), if you do this your CCleaner folder should be 2.1 MB now.

Ralph 2011-02-21 00:51

Great tutorial on how to add entries in "Winapp2.ini":


Magibon 2011-04-04 19:28

the link for "list of unofficial programs" is not working.


the_watcher 2011-04-26 16:39

i was ready to update the post with the correct link to the "list...". guinness did it first :)
always one step ahead :)


Technomancer 2011-04-27 17:29

I've used CCleaner since I first found it a few years ago. It gets better every time they bring out a new version and it's safe and easy to use.

I've made a couple of donations to them and if you REALLY like it it helps them to develop it further.


zak_711 2011-05-26 16:22

The list of unofficial programs works only with installed programs; f.e. cleaninig opera portable requires manual entry of relative paths


Emka 2011-05-27 04:08

Oh, what do I have to add to winapp2.ini so that it cleans portable Opera just as thouroughly as an installed one?


zak_711 2011-05-27 15:13

I use the "brutal way"; as they don't know ( in C Cleaner forum ), I run opera.exe; then you can see ....


Tripod 2011-06-16 12:23

Superfluous language dll's in /lang (currently totalling 1.26MB):

To follow up on this further: as per message posted at piriform forums below (url munged by this site's posting script, reconstruct manually from the visible), it seems that English (GB) and English (USA) at least are built into ccleaner.exe itself as these two are listed by respective decimal numbers in the page quoted below but do not appear in the /lang subdirectory of ccleaner; so if you want only these languages just delete all the lang-*.dll's...

Posted 12 May 2011 - 02:50 PM
Look at the "Decimal" column.
English is included into the program.


juvera 2011-11-04 01:01

CC is possibly a great tool, but it does not clean LSO-cookies.
I believe there are LSO-cookie killers around, some even portable, but to the best of my knowledge you can create your own portable LSO-cookie killer. Here is how:

Step 1: On your desktop create a text-file. I named mine: nolso.txt

Step 2: Copy these 2 lines in your file:
rd /s /q C:\Users\XXX\AppData\Roaming\Adobe
rd /s /q C:\Users\XXX\AppData\Roaming\Macromedia

You must replace XXX with the name of the user logged in.

Notes: rd means remove directory. /s means: remove recursively subfolders, /q means do not ask for confirmation.

Step 3: Save your file

Step 4: Rename the file nolso.bat

Step 5: Run it every time you want to get rid of these respawning cookies.

Comments and additions are welcome!
How can you know when you are doing the right thing right!


dany 2011-11-04 02:44

1. CCleaner does remove LSO's. Under Application > Multimedia and make sure you tick Flash Player. Go on the internet and get some LSO's, visit youtube or something. Scan with CCleaner. The results should show 'Multimedia - Flash Player' entries. Right click and choose 'view detailed results'. There are your LSO's.
2. You are removing way more than just the LSO's in your bat there...


juvera 2011-11-04 03:50

@Dany, Thank you Dany. I double checked: CCleaner does not remove these folders on my system (Win7). I do not know why, but I believe you.
My bat removes the two folders that are re/created at the moment I enter the web sites using these technologies (date/time match). Therefore my conclusion is that these folders are used only by the LSO web sites, and it does not harm my system to delete them.


dany 2011-11-04 12:53

@juvera win7 x64 here and well, um, the LSO's get removed on my machine... weird, maybe a permissions issue.
It won't cripple your system, but afaik that's also the location where Adobe stores the update logs and certificates etc... since CC works for me, I let CC handle it all.
Use the variable %APPDATA% in your batch, much cleaner and also 'portable' in a way. It expands to C:\Users\XXX\AppData\Roaming

Ruby 2012-02-23 19:52

In the [ How to extract ] it says to [ Launch CCleaner.exe (or CCleaner64.exe for 64-bit) ] however, launching 'CCleaner.exe' will run a OS/System check and launch the correct 'bitness' (i.e. CCleaner64 for 64bit).
So, if you use a launcher; just assign 'CCleaner.exe' and make sure both CCleaner.exe and CCleaner64.exe are in the same folder.


guinness 2012-02-23 21:15

Thanks for the tip, I was using a custom launcher but seems this isn't required anymore.


SYSTEM 2012-02-24 12:38

Thanks Ruby. :) I have edited the extraction instructions.

juvera 2012-05-26 21:33

This version of CCleaner seems to have cleaned the Flash cookies on my machine!
But FireFox Addon: Better Privacy 1.68 did not!


juvera 2012-05-28 19:11

Sad update on the cleaning capabilities of CCleaner.

Yesterday I was triumphant, because I had the impression that CCleaner had cleaned my computer from persistent cookies.
That was based on a test on Youtube immediately after running CCleaner: the videos I watched last Fall had at last disappeared from the right pane. But today, the cookies have had
enough time to be resurrected, either from a steganographic code in a png file or from a marketing firm that is keeping track of what I am doing on my computer.

CCleaner cleans some of the cookies, but to be efficient a cleaning tool should be able to clean the THIRTEEN locations where persistent cookies can be stored (, otherwise the cookies are re-spawned.


TP109 2012-05-30 09:11


Good info


shodan816 2012-06-26 11:04

At least one problem remains in the latest version - V3.20.1750. If you COPY either your SendTo menu or your Program Files menu (or any part of it) to a TEMP folder and then delete the copy from there to the Recycle.Bin, CCleaner will delete the folder contents (the *.lnk files) but not those folders themselves. Looking in Windows Explorer, it APPEARS that CCleaner deleted them, but viewing them through a superior file manager such as XYplorer, or better yet from the Command Line, you will see those folders still exist.


Shadeclan 2012-09-14 19:02

Can't live without this app. I don't know how many problems I've fixed, with others' computers as well as my own, just by running CCleaner once.


guinness 2012-09-26 12:40 has just push the 1000 programs mark for cleaning additional applications that CCleaner doesn't.

Mixture 2014-09-29 00:14

Version 4.18.4844 acts too differently from version 4.7.4808. I definitely do not need Active Computer Monitoring. When I clean my browser history with CCleaner, I cleaning it manually, not when someone else tells me to. There's far too much interference in my life from other humans. I am staying with version 4.7.4808.


__philippe 2014-09-29 13:39

Turns out CCleaner 4.18.4844 "Active System Monitoring" can be turned off, after all:

1. Open CCleaner, then click Options > Monitoring
2. Disable System Monitoring by unticking the box next to "Enable System Monitoring"
3. Disable Active Monitoring by unticking the box next to "Enable Active Monitoring",
and click Yes when the confirmation box appears

See here for an ongoing discussion about "Active System Monitoring" usage:




Mixture 2014-09-29 14:57

__philippe, thank you very much. Thank God for disable switches in this software. Too bad I can't do the same thing to the NSA and the EPA!


Napiophelios 2014-11-26 00:25

This is terrible;
CCleaner wont let you resize its window but so small
and when you maximize the window, it covers the taskbar
so its actually going full screen.

tiles media links..I hate it.
I think I just stopped updating one of my faves.
I am certainly removing my vote..not that it would matter.


webfork 2014-11-26 01:35

Napiophelios: I can resize the window ok and I'm not having any trouble with the taskbar being covered up full screen. The tiles aren't great but the social media junk is pretty far down (options - about). I'm not sure I see the problem. Is there something different with the 64-bit version?


Wolfghost 2014-11-26 01:52

Nope works great with resize window in 64bit.
But GUI is terrible !! Hope we can switc back to good 7 style in future!!


Napiophelios 2014-11-26 17:04

well I am using a little Asus netbook and I have never had it act like this before this update.

I imagine the tiles arent resizable so they have to have so much room to look pretty I guess

it still sucks
even if its just happening to me :)


joby_toss 2014-11-26 17:58

@Naphiopelios: no, my friend, you're not alone in this. I'm also having trouble with CCleaner's maximized state. Because of my PowerPro bar, CCleaner's window goes off-screen. I do consider this a bug, because none of my other apps behave like this, not even CCleaner version 4.

The last version of CCleaner which doesn't use the abominable Windows 10 flat style GUI is 4.19 (4.19.4867). I voted it down, I have zero tolerance for flat ugliness.


misan 2016-04-12 14:45

@smaragdus : It is bearable.


Billo255 2016-04-27 03:00

Not sure if it's just me but the link to download CCleaner bounces me from page to page on the Piriform site. Pressing the "download" buttons takes me to a different page. Even when I got to the download page that gave me the option to download the portable version that button just redirected me to another page. At some point it takes me back to the original page it redirected from but when I click to download it offers the installable version and not the portable version.

Any way to bypass all the redirects (assuming I'm not the only one having this problem." ?


Billo255 2016-04-27 03:03

Nevermind. After 5 tries (and not sure what I did) it gave me the portable version to save rather than the .exe version.
