I ran Wise Care after running KC Cleaner and had 388 MB of Invalid Files plus 39 Invalid Registry Entries that KC Cleaner missed. The most I've ever had left over after running Win Utilities was 42 Invalid Files that Wise Care found. Plus every time I run KC Files it also removed some privacy extensions that must be reactivated when I start Firefox again. This isn't such a great cleaner after all.

Wow! my C hard drive space went from 4 GB to 50 GB of free space.
All I selected was to delete cookies and internet cache.

I would prefer to see what its going to delete first but there might be an option for this.

Good job KCleaner.

NEVER delete without inspecting first.

KCleaner once deleted an entire hard drive on me, Windows and all -- ooops!

How does one even quantify the efficiency of a "hard disk cleaner" let alone make such a claim like "The most efficient Hard Disk cleaner." Are there any comprehensive independant studies that Kyle can produce to support his outlandish claim and quantify what it means to be an efficient hard disk cleaner?

Is it not so efficient on Solid State Drives (They are not "disks" as nothing disk shaped in them.)
I bet it is just another of those meaningless marketing lies that is all to common nowadays.

The comment is a joke, based on the advertisement up front:

"... KCleaner is designed to be the most efficient Hard Disk cleaner, tracking every useless byte in order to give you all the resources you may need for your documents, music, pictures, movies ..."

More importantly, anyone can try it and use it and see if they like it rather, than ask others if they will like it.

Always good to have backups and try new things.

I like to know HOW MUCH was cleaned out. Wise Care and Win Utilities give that information after a cleaning. Would be nice if this cleaner would also tell us exactly how much was cleaned out. Otherwise, it's OK......I guess.....really don't know.

I was particularly interested in KCleaner because of a problem I've been having...

Windows 10 cumulative updates usually grow Windows footprint by about 2-3 GB. Windows Disk Cleanup or Storage Sense should get rid of most of that added bulk, but for the last couple few months it hasn't always worked -- some updates Disk Cleanup only worked on one or 2 of the copies of win10 on our devices & VMs, other times only one or two didn't work. After the next win10 update, e.g. September's 2nd cumulative update, Disk Cleanup would usually work to get rid of the garbage from the current & previous update.

What I found is that KCleaner looks like it would be better cleaning out the 2 Windows temp folders than WIn10's 2 built-in solutions, but it isn't as comprehensive as Cleanmgr+, which offered to clear out an additional 20 MB in a win10 VM where Disk Cleanup did not work last Patch Tuesday. Neither would/could do anything about the update bloat I was trying to get rid of.

neowin[.]net/news/cleanmgr-125825

That said, I use the privacy mode in web browsers so there's no need to run an app just to cleanup afterward. sammie posted that: "KCleaner offers what CCleaner does". Partially... e.g. I've used CCleaner to uninstall some of win10's Store apps that win10 itself doesn't provide an uninstall for.

You can find anything on your hard drives based on size with an easy details list using WinDirStat. I would say WinDirStat is one of my favorite free software programs out there for any computer.

I only use the Windows 10 inbuilt cleaning system now. I have found it unnecessary to use any additional ones at all.

Reply   |   Comment by Niv  –  26 days ago  –  Did you find this comment useful? yes | no (+5)

Niv,

Aside from Disk Cleanup not reliably cleaning up leftover win10 update files for the last few months, win10's built-in solutions seem to leave an awful lot behind in Windows 2 temp folders. Also, if you're trying to shrink Windows footprint, don't forget about the possible hibernation file and accumulated System Restore data, each of which can be several GB.

Reply   |   Comment by mike  –  26 days ago  –  Did you find this comment useful? yes | no (+7)

Niv, For others.... As in: Disk cleanup in Windows 10. In the search box on the taskbar, type disk cleanup, and select Disk Cleanup from the list of results. Select the drive you want to clean up, and then select OK

Too unpredictable for me. And I would expect also for others. No instructions could I find. Thought to give it a try and to be ultra cautious at first. Glad I was. So In settings I cleared all ticks and then selected just my recycle bin thinking that must be safe. Clicked on clean and expected a confirmatory window but it just seemed to immediately start deleting files. (Maybe I clicked twice just feeling my way in) I watched for a minute or so then a window popped up saying something like "you need administrators permission to delete this file" and indicated a file on my C drive NOT IN THE RECYCLE BIN was attempting to be deleted. This seemed to hold up the the Kclean program (Thank God). Not sure what to do I immediately went to task manager and ended the program. Take heed of the unfriendly warning. "Powerful ...Use with care". Not till there are proper instructions Thanks

D Murphy, Yes, God saved you from being damaged by the KCleaner. But, sadly, the time He spent doing that meant others across had to left without His help - with disastrous results.

Reply   |   Comment by petrop  –  26 days ago  –  Did you find this comment useful? yes | no (+1)

D Murphy,

1 - Click [ Simulate ] first to see what will be deleted

2 - tick or untick offerings in the results

3 - click [ Clean ] to actually clean.

It's just poor design intended to be one-click for the thoughtless and impatient who do not want to know minutiae.

There's nothing wrong with 2 or 3 clicks to make a program actually do it's final task, and is much safer.

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.

I used a cleaner awhile back that was giveawayoftheday and it ate my saved passwords too. I don't consider those useless files and had to go back and get my passwords and reset most of them and had to even change some because they don't want you to use a password you have used previously etc. So, I am wanting to know if this cleaner also might do that... If so I don't and won't even try it. I will await an answer before I proceed myself, Thank you...

DrPseudo: Idk about KCleaner, but CCleaner is a great free program and you can choose what you want it to clean. As long as you don't check the box to remove "saved passwords" it won't remove them.

Reply   |   Comment by Grammie  –  26 days ago  –  Did you find this comment useful? yes | no (+14)

DrPseudo,

KCleaner did not eat your saved passwords.

Maybe it cleared your cache where copies of passwords are saved for auto use in web browsers.

If you do not know your passwords, that's your responsibility.

If you use a web browser that can sync ( Chrome, Firefox, Opera ), there's your passwords.

At least now you know how to scrub your computer if you want to give it away, or let someone else use it, or if you fear it might get compromised by public intrusion ( say, before traveling and using it in public ).

It seems to me that every day, almost without fail, someone wil ask a question based entirely on their own inability or unwillingness to read the instructions in the first place
If people weren't made to feel just a mite embarrassed in asking, the comments section would become very boring indeed. Why they able to read the answer in the comments section but not in the original 'Read- me' is beyond me.

Neil H, Thanks to Perry Smith and William for the help and support.

I was in a rush to go out this morning and didn't mention that I had also tried 'GiveawayoftheDay' in the 'Name' field, I didn't mention that I was also drinking tea, just in case someone shouted that I should be drinking coffee! There are a lot of other facts that 'landfill' is ignorant of too, can't imagine that their life is much fun from the reaction my comment brought from them! I tried my name and the email as possible alternatives. I had also tried re-installing the software and used all of those possible entries in the 'Name' field. I didn't mention that either. After the third re-install the software registered OK.

For landfill's information, I did read the .txt file, thoroughly, more than once, while wearing some glasses that came from Specsavers, they are new and work just fine. I am literate and computer literate, I first programmed computers +30 years ago. You may be interested to read a definition of 'landfill' - "Landfill is the disposal of waste which cannot be reused, recycled or recovered, into or onto land. It forms the lowest aspect of the European Waste Framework Directive’s waste hierarchy." - https://www.sepa.org.uk/regulations/waste/landfill/

Having a bad day as part of the lowest aspect of the waste hierarchy?

Reply   |   Comment by Terry I  –  26 days ago  –  Did you find this comment useful? yes | no (0)

Terry I, I'd say PROBABLY because they do not extract the zip contents unless they have to and there is NO sticky short FAQ added to the top of the comments section so everyone sees the bare essential instruction to read the readme.txt on every giveaway... and if you have not read the readme.txt and have ANY questions about the giveaway installation or activation/registration read the readme.txt before posting any comments in the comments section and include a checkbox when posting a comment to assert you have read the readme.txt file as a subtle reminder.

There is no justification for belittling a new visitor for being inexperienced and maybe lazy out of ones own impatience or lazyness. It is bad for ones own reputation and bad for the site to not welcome new users! But to be honest landfill was not that rude and not very insulting or brutal, just a little direct and impatient in my opinion, but not the best ambasador for this site.

If people were made to feel a mite embarressed by their asking a simple question for their first time then I would not blame them if they thought "sod this I did not come here to be abused!" And never come back.

Now if they kept asking the same question every day and the answers were always in the readme.txt file or in the description above or a sticky post by GAOTD or the vendor then I would hope the moderator would view the users regular spamming with the same question as spam and stop letting the users spam post out into the public since the person must know the answer by then. Remember not all giveaway activation problems are solved by reading the readme.txt file. Sometimes it may be the vendors own activation mechanisim failing in some way not covered in the readme.txt Or lack of license email arriving from GAOTD site due to GAOTD inadequatly granulated unsubscribe systems where if you unsubscribe from any one email you received you unsubscribe from everything even if you want to receive other things but say not the emailed newsletter or no more email notifications to one particular comment thread... Readme.txt is NOT the answer to everything and likely never will be... and if it ever is it will be too long a read for most people to go through as it will end up longer than many EULA that are too lnog for most to bother reading and are blindly accepted without a second thought by most people.

Liright47, all junk cleaners are suitable for use on SSDs. In general, you can use a SSD exactly as you would use a hard drive. The only exception to this, is that there is no need to ever manually defrag them. It's important to note, that unlike what many people claim, it is safe to a defrag a SSD. However, because of the way that they work, any performance gains will most likely very minimal at best.

Reply   |   Comment by Roger  –  26 days ago  –  Did you find this comment useful? yes | no (+2)

Liright47, Yes and you won't suffer for that. But it's not necesarily bad for them either but ONLY if the program does not EVER delete any files that will be recreated by windows after it has finished since that just increases the total number of writes to the drive for no good reason. For example if it deleted the hiberfil.sys file without disabling hibernate or hybrid-sleep it would get re-written by the system, same for swapfile.sys or pagefile.sys etc. I would hope the program does not touch those files but cannot say as I wouldn't run it on any of my ssytems unless someone paid me to ... I'd then try it in a virtual machine but not on a real computer.

Personally I would not use this type of program on any of my machines and only would go about cleaning things manually I wanted to clean if space was getting tight in any way. Generally speaking SSD based machines are far less prone to slowing down as space gets consumed, and files fragment, due to the lack of mechanical seek time that magnetic hard drives suffer so there is not such an apparent need to do much about it until it becomes a free space issue... and in that respect it is better to move as much of those temporrary files that can be safely cleaned to other non-system drive partitions to save mussing up the system drive and avoidable writes the the system SSD letter.
