[ Wise Disk Cleaner and Glary utilities ],

KCleaner finds things the others you mention do not, AND the pro version can clean automatically in the background.

dadams, RK is NO LONGER present

.
[ dadams ],

No, not the GOTD version, but clean your system of RK and other tagalongs periodically anyway.

Erica,
Last I knew the clap and other STD's were free ! Complain or not?

Nigel, NOPE!

Your fault for not checking the person out or using protection in the first place.

Abdul Shakir, please copy/paste both name and code as provided

Robert, since Piriform (developer of Ccleaner) was purchased by Avast Software, it's known to have spyware/security issues. I've removed it from all of my machines after using it for YEARS. BleachBit and others that are known to still be "clean" are free, but why not try this freebie out? Just sayin'.....

Robert, just saying and from what I have read. Did you read this to?

https://www.ghacks.net/2018/08/01/ccleaner-5-45-dont-install/

https://forum.piriform.com/topic/52532-how-much-does-version-546-spy-on-you/

https://thehackernews.com/2018/04/ccleaner-malware-attack.html

I wonder if it's wise to use CCleaner anymore after reading those articles?

.
ROTF LMAO at [ Robert ], wanna-be trademark attorney / ambulance chaser with zero references and zero clients.

French KCSoftwares and KCleaner have been around since EARLY 2000s.

English Piriform registered CCleaner trademark in the LATE 2000s in territorial US.

Being descriptive, Piriform has no exclusive use of any [ ?cleaner ] pattern.

Any user of both products can testify to them being completely different in every presentation, process. and productive result.

Also consider web searches for these existing products:

ACleaner
BCleaner
DCleaner
eCleaner
FCleaner
GCleaner
HCleaner
iCleaner
JCleaner
LCleaner
MCleaner
nCleaner
QCleaner
RCleaner
SCleaner
TCleaner
uCleaner
VCleaner
WCleaner
xCleaner
Z-Cleaner

frank,
To sue Robert, KCleaner would have to make all their code public to make their case. Considering the similarities between CCleaner and KCleaner (including the name), ANY lines of code that were identical would cause them to lose their case AND CCleaner would then have an iron clad case against KCleaner that KCleaner proved for them. Do you think they want to risk all that for Robert's comment? I think not!

Robert, keep using CCleaner then I have both Kcleaner cleared 376.37 meg more than ccleaner did with the same settings

But go ahead set yourself up with a possible slander suite (also in America against your laws) Have a great day ;)

.
[ Susan ],

No, to sue over trademark does not require releasing code, just like Coke can sue someone for using the trademark "Coke" without permission, but does not have to divulge the formula for Coke.

You're thinking design patent or copyright, totally different issues, and KCleaner and CCleaner are nothing alike anyway ... and neither has any patent or copyright registrations to sue over.

Richard, please copy/paste both name and code as provided

[ Richard ],

The free version just has a nag at exit, but works the same, no need to register.
.

Richard,The code works fine registered fine on all my pc's and all supported OS's Make sure you don't have any spaces at the beginning and end of both username and key ;)

James R Baxter, Of course. So?

James R Baxter,
WELL that's a PLUS........I used CC for years and THEN some updates changed it all and every time I use it, it DELETES or ELIMINATES some of my Camera, Scanner, and HP printer Programs AND ALL MY SITE SAVED PASSWORDS, some of which I DON'T know anymore.
Then it's ""install or register" them again....couple hours down the drain.....
I've clicked every box at some point to make it quit........that don't work either.
Maybe I'll see if I can install this and give it a try.........

Bazzr,
It's called wipe your hard drives of useless junk that could slow down the performance of your computer and, or, browsers.

.
[ frank ],

[ Bazzr ] is afraid it might wipe a hard drive.

I know that it did wipe one of mine.

An earlier version cleaned my entire drive of all files not in use, including my documents and Windows stuff,

... but that was only once,

... and I should have noticed it was about to clean 100 GB of content, and not clicked [ Clean ], but instead exited and rebooted,

... this has not happened in recent versions,

... but ALWAYS select [ Simulate ] first, and inspect the results, before selecting [ Clean ].
.

Robert, finds more junk file + has an automatic background cleaning

Robert,
See what I said above about CC..............

Ivan, Yes, accept that CCleaner now collects your data and sends it back to them. I had pro+ and uninstalled it because my data is none of their business.

glnman, My good heavens, what next, thanks for the info, is there no privacy left in this world, I doubt it, not with the way the Government is going, I do not trust them or many software makers, So now, I thank you and I shall now get rid of Ccleaner. Your quite right, it is none of their business about your data, life, or information personally about you. Who do they think they are, "Facebook" who is under investigation I might add for using personal information of the people who is it and then they lie to you and say they do not. Go over to https://www.eff.org/ and read all about it, Electronic Foundation Order, they exist for our rights and privacy. Again, thank you.

mjjohnah, Hi good point, but I still took it out, often times I find out, even though they say you can turn it off, it does nothing at all and still sends info back. So I removed it anyway. It is getting to the point it is not worth having a computer, cell phone among other things, so much for the USA Constitution for freedom and privacy that Trump has totally destroyed sorry did not mean to become political but that is about what it comes down too. I think I will move to Mexico, that should upset him.. :)

Ivan, what relevance is AOMEI Backerupper Pro to the discussion?

Are you not simply trying to sell something else by dropping it into the conversation?

Bob, never made a mistake, or hit a wrong key? Bob get off!

Bob,

"You think that you would spell better and ...."

After reading that attempt at a sentence, I am surprised that you are criticising another's grammer!!!

glnman, Use a two way firewall and you won't have anything leave your computer that you don't ok first
I use Private Firewall.

ilikefree, how are you getting Private Firewall to work on windows 10? The update removed it, and now I can't get it to re-install. I feel so unprotected without it.

Susan, Right on.

ilikefree, I'm aware of this. I use a VPN, OpenDNS, a hardware firewall and a software firewall and an antivirus/antimalware program. Before I retired I built and repaired computers so I'm somewhat familiar with the problems associated with internet privacy.

Mardel, thanks nice review !

Mardel,
Thank you for the useful info but why does GOTD make it so annoying to click on a link?

Mardel, Is KCleaner a worthy alternative to CCleaner?

The biggest downfall to KCleaner is that its filled with bloat ware that can cause troubles during install. While KCleaner and the folks behind it use this as a way to provide freeware, it can be a nightmare to uninstall. KCleaner offers what CCleaner does, in a less visual format. For some users, CCleaner’s easier to use format could be what draws them to it rather KCleaner. It’s up to you which title would be better for your PC. KCleaner is just one alternative that lives up to the hype when compared to CCleaner.

.
[ Check the facts ],

Yes, [ Relevant Knowledge ] must be removed after installing certain versions of KCSoftwares.

Use the Zip portable versions insead.
.

Check the facts, WRONG, no sponsors, 100% clean software and installer.

I was talking about the kcleaner portable version, obviously.
It removes the folder on exit.

I forgot windows disk cleanup: 31.3MB and 50.4MB (with cleanup system files).

xilolee, I do not trust products by "WISE" , just thought I'd let you know , oh I have never had a low result as implied from Crap Cleaner .

Hi mjjohnah. :-)

I'm using their programs without problems since years and I'm a (volunteer and not paid) moderator on their forum.
I'm trying to bring to their attention all bugs in their programs and hopefully they're always better.
Like you saw, I'm constantly doing comparisons with other software.
Anyway, every software could have bugs and problems, even the ones developed by microsoft, therefore doing a "full system image" AND a "complete backup of important files" is always recommended before trying "disk cleaners" or "registry cleaners" or "windows tweakers" and so forth...

mjjohnah, I like the Wise Disk cleaner actually, can secure delete cache and recycle bin. Very configurable.

Henry, Scary thought, thanks for the heads up.

Henry, yes it does, just enable "expert mode" then "Simulation"

Kyle Katarn, thanks, but that is really "logical" and "user friendly" on such important feature, no wonder Henry couldn't notice it.

Yanco, ok, i'll make it easier

I agree as I would not want a program to delete something valuable on my hard drive. There is no way of knowing what I want to keep.

Hi Bob. :-)

I think Kyle intention was to keep the program simple and user-friendly, for beginners.
Intermediate and advanced users can switch the program to expert mode (because they're not beginners).

.
[ Henry ],

ALWAYS select [ Simulate ] first, and inspect the results, before selecting [ Clean ].

NEVER select [ Start ].

xilolee, exactly !
