Comments on AthTek Registry Cleaner 2.0

Thank you for voting!
Please add a comment explaining the reason behind your vote.

I have used registry cleaners forever. Never had an aggressive cleaner like this one before. I know.....you say don't clean the registry. With a paragon backup image always I feel comfortable trying new software. I am on here everyday like a lot others looking for something better to use in my tool box. I download and uninstall hundreds of programs during a years time. Someone on here suggested Revo Uninstaller....well run a search (Everything-free) for files left over and you will find them even after running Revo. Today's took out a file that was needed to start my PC. Some of you righteous folks will say be careful and select only those you feel comfortable deleting. I have no way of determining which of the 1600 files this program found that is safe to delete. How much time is consumed going over that many individual files? Luckily last known good configuration corrected the problem. I used restore the registry option in AthTek . Uninstalled AthTek with Revo. Deleted files left over that Revo missed. Life is good.

Wise Registry Cleaner (Free version) has never caused any problems to my PC after cleaning. You can do backup and restore the registry.
You can choose to delete old backups.

Wise Registry Cleaner (Free version) is one of the best I have ever used. Not overly aggressive. Excellent user interface.

As I stated earlier that I would repost if I encountered problems. Yes, I did. The invalid entries that were found were not all invalid, and some personal settings had been changed too! It also mysteriously put small locks on all my folders, etc. Consequently I withdraw my thumbs up to a Big THUMBS DOWN! And I apologize to any that may have installed program from my recommendation.

Works faster and eliminates a lot of errors that AthTek 1.2 x64 wouldn't remove. This is one of the best reg tools I've found. But no reg cleaner should be used by people not proficient in understanding what is OK and what is not OK to remove. That's most users. BTW AthTek makes security tools the the Los Angeles Sheriff's Department uses for forensics. i.e NetWalk. (my job)

Why do so many reviewers read a post here and follow the leader by posting "Me too!" instead of trying this? Seriously, so many comments from people who haven't used this or even read the help or the publishers website. This is good software for the right user. Not everyone should use this. Only if you need and truly understand what it does and does not do.
I dislke seeing software slammed as "bad" when many comments show that people just read one comment and decided to "follow the leader". I guess more for me. Thank you GOTD and AthTek. And thank you #41 Mike for your post. Very good summary.

I clean too much.This cleaner with a nice layout found many entries not detected by CCleaner on my Vista laptop, but deleted a serial of one application, returned another to demo and made my Sony Vegas Movie Studio to abort on launch.The restore option of AthTec registry cleaner did not correct the Sony Vegas Movie Studio problem, something Vistas system restore did.
I guess too much and too deep registry cleaning will inhibit install of some advanced copy protected software like Movie Studio as this program (handshaking online etc.)on my laptop only would install from a new admin. account with a fresh registry when I bought it.Aftter transferring documents etc. from the original admin. account and hereafter deleting the old admin. account reinstall of Windows was avoided.

@mike (#40 & #41):
You have posted the most sensible, logical comments in the entire thread, thanks.

ERUNT is one of those un-glamorous tools which don't get a lot of publicity, but it is exceptionally useful, and should be a part of any computer user's security arsenal. I use it religiously 2x per month.

And you were the only one to point out that the uninstall part of Revo Uninstaller Free (a very good program, btw) is, in effect, CLEANING the registry when it asks you if you want to remove entries left by the just-uninstalled program. It is making educated guesses at what to remove, and usually, its suggestions are spot-on, but Revo CAN make (and HAS made, in my case) mistakes.

The only way to avoid this situation is to use a "before & after" snapshot tool when installing new software. In this method, the tool compares what the registry looks like before the new software is installed with what it looks like after, and logs the differences. Then, if that software is later uninstalled, the tools knows EXACTLY what was added to the registry, and can remove it if necessary. Programs which utilize this method are REVO Uninstaller Pro (which mike mentioned) and Ashampoo's Uninstaller 4, a paid program, and the one which I use.

There is a downside to doing it this way-- it can be a slight pain in the neck. Installing any new program takes a bit longer, and requires patience and discipline on the part of the user (something which many people might not have!). However, the result is that even after installing and uninstalling hundreds of programs, there is very little extraneous matter left behind in the registry.

Thanks Giveawayoftheday and AthTek Software. Thus far after installing on laptop, windows 7 home 64 bit, the reg cleaner found 864 invalid entries. Of course I backed up my whole reg separately before I had it clean the invalid entries. I must say, I have seen a better performance overall, and I opened up and ran all my installed software flawlessly. Therefore, I give it a thumbs up. I might add that I too use Glary Pro Utilities and today's giveaway the day, AthTek Software certainly found many more invalid entries than Glary had! If before the giveaway expires I encounter anything differently, then by all means I will repost my findings.

#29: "Fake awards…… suspicious.
“Registry cleaners” …. snake oil."

Purely FWIW, there are 2 cautions I'd add to any discussions of alleged fake awards &/or company info... the 1st is that many people tend to think solely in terms of the west, but the world is really a pretty big place. :) Now I didn't see any advertised awards on the AthTek page linked up top so I can't offer any specifics, but generally speaking the sort of sites that offer awards also have regional sites, different language sites etc., & those often are more-or-less separate entities, with reviews & awards not shared between them. An award from the China version of a site is no less valid when it's not carried over to the US version. Does that mean every award every company lists is legit? Not at all. But I've found by checking out these regional sites that sometimes when a company's blasted for fake awards the person doing the blasting never checked those other sites. :)

Use whatever criteria you're comfortable with when choosing whether or not to try out whatever app, but realize that you may lose out when passing up any opportunity, so maybe try to set that criteria as fairly as you can for your benefit -- not just theirs. :) As far as providing a physical address, maybe it's stupid not to, maybe not providing an address increases sales -- I've no idea, but I have seen anti-China [or anti *Any* country] bias. Personally I give an awful lot of weight to the GOTD team's judgement -- this is what they do after all, providing GOTD offers from reputable companies. Besides being good at what they do, it's simply not in their own best interests to showcase a bad company nor it's wares.

The 2nd caution I'd humbly add is to be as realistic & practical as you can when deciding what companies you'll deal with, applying a good dose of skepticism, *no matter who they are*, for your own protection. Effective Sales & Marketing is by definition not just misleading but deceptive. Many's the time I've seen a comment blasting the company behind a GOTD offer, only to then read them extolling the virtues of another, often American or European company that's known to be 10 or 20 times worse -- they're just much better at the deception part. That's the main reason I don't pay attention to awards, real or otherwise, since they can most often be bought, same as positive magazine reviews.


As far as registry cleaners being snake oil, I believe that's all in the marketing -- they are what they are, a sometimes useful tool. Very, very few companies or products live up to their claims entirely, & companies selling registry cleaners & system optimizers are usually really great examples of over-hyping your product. You might [or might not] give AthTek a *little bit* of a pass because it seems they could use someone more skilled at English, e.g. "...it can find more registry entries than any other registry cleaner" -- I'm assuming "entries" should be "errors", though undoubtedly that would still be unprovable hype.

Registry cleaners can help or harm -- they're a double-edged sword. They can't do as good a job as a live person editing the registry, but they don't require knowledge or skill & they're quite a bit faster than manually wading through, deleting hundred or thousands of registry entries. Because they're not a live person they don't *know* anything, but rely on hard & fast rules that aren't as efficient and don't allow for everything software coders might stick in the registry, which is where or how they often break things if/when they do break something. That said, if you've got a good backup [& I don't mean the one built into any reg cleaner], the most trying something like AthTek Registry Cleaner can cost you is the time it takes to restore that backup. Some people do report registry cleaners have helped -- enough people that I don't believe it's solely placebo effect. But if you're not prepared to spend the time/effort creating that backup, *& learning, being able to restore it*, IMHO you should stay far away from this sort of thing.

"If you’re running Vista or Win7 you do not need to EVER defrag your registry. EVER."

No, & you don't *Need* to do lots of things, whether we're talking about eating your veggies to practicing defensive driving. But like changing your car's engine oil & filter more often than the max interval recommended by the manufacturer, it can help make things last longer, run better. Windows registry is stored in files -- those files have to be read -- opening & reading a smaller file takes less time than a larger one... you can verify that using Notepad. Now with the registry you're talking about an awful lot of entries to make a noticeable difference in the file size, & on current hardware it will likely take a pretty large increase in the size of the registry before you start noticing a slow down, but eventually it can accumulate enough size to make a difference. That's why there's registry cleaning & cleaners in the 1st place.

As far as defrag goes, there's the physical files that can be defragged like any others -- Page Defrag -> http://technet.microsoft.com/en-us/sysinternals/bb897426 -- Ultra Defrag -> http://ultradefrag.sourceforge.net/en/index.html . As a database the registry can also accumulate dead space -- maybe think of opening a new text file in Notepad, typing your 1st name, holding down the space key for several seconds, then typing your last name... delete all those spaces & the file's smaller. They're older apps, but ERUNT & NTREGOPT [included with ERUNT or avail. separately] work in win7 [see the note to read the FAQ] -> http://www.larshederer.homepage.t-online.de/erunt/ . NTREGOPT simply writes a copy of Window's registry without the empty spaces, then swaps it for the live copy of the registry on re-boot. It'll usually make the registry files physically smaller. Neither defrag process will change the registry contents, so neither will fix anything -- Windows will read the registry just as well before & after, but after it'll hopefully do that reading just a bit faster.

#14: "BUT the program backs-up the registry automatically before starting unless turned off manually, so any problems can be easily repaired by restoring the old Registry."

Please be careful... As Allen reported [#23], he couldn't get into Windows at all -- if you can't get into Windows there's no way to run any registry cleaner so how will you restore that app's registry backup? You can restore an ERUNT registry backup or something like a Paragon disk/partition image backup from a boot CD/DVD/USB device.

Also note, I used to see this frequently on-line a few years back, & some people still talk about backing up their registry by exporting it to a file(s) using Regedit. That will work with registry keys -- It Won't Work With The Entire Registry -- you'll get your exported registry all right, but you can't merge it with the registry to put things back. Parts of the registry are in use when Windows is running, & those parts can't be replaced or changed unless you get out of Windows -- that's one reason for a restart after some installs &/or updates. BUT, you can't merge a .reg file into the registry unless Windows is running, making your full Regedit backup useless.

* * *

#23: " I tried using a registry cleaner/defrag auslogics on my win7x64 system as soon as I Clicked ok to reboot it tossed my computer into a loop and it took me 3 weeks (Thanks to My BEAUTIFUL Wife for all her searching and hard work) to get it figured out. I have since discovered you do not mess with the registry in win 7 I do use ccleaner to clean it and that is it. And I use an uninstaller whenever I uninstall a program. Windows 7 seems to defrag the registry on its own from things I have read."

Everyone should backup their system regularly, especially before messing with the registry, & it's a good idea in win7 to both do an ERUNT backup & set a restore point as restoring either might be a bit quicker than restoring a backup. I'd choose the restore point 1st, but you can restore the ERUNT backup even if Windows won't start. I'm Not trying to say Told Ya So or anything like that, but it is a very good example of why everyone should back up -- instead of 3 weeks it would have taken maybe 3 minutes to restore an ERUNT backup, maybe 10 minutes to 1/2 an hour for the average system to restore a Paragon disk/partition image backup. As far as the win7 registry defrag goes, whenever I run NTREGOPT the registry gets smaller, so if win7 does defrag, it certainly doesn't do the best job of it.

#36: "Use Revo to uninstall something, and you won’t need any ‘registry cleaner’ to come along some time later and start finding stuff which turns out not to have anything to do with whatever you may have uninstalled earlier."

From the Revo site... Revo Pro: "...To remove a program completely, and without leaving a trace, you can monitor all system changes made during its installation, and then use that information to uninstall it..." The freeware version is a registry cleaner, essentially the same thing as today's GOTD.

The longer windows has been installed, the more programs have been installed/uninstalled, the more the outdated entries accumulate in the registry. This has no great detrimental effect on the actual functioning of your computer once a program is running, BUT - it does slow down windows startup when the entire registry is read, and it can slow down individual programs loading as windows reads their data from a bloated registry.

I have always been satisfied with CCleaner. It is small, quick, free, backs up the registry, and after scanning displays a list of what it considers unnecessary entries, and removes nothing til you tell it to.

@ post 32, Peter: QUOTE: 'You would think there would be some benefits to PROPERLY cleaning a registry after all the installs and uninstalls some of us do. . .'

Yes. There are. And that's what the always-free Revo Uninstaller is there for. Because if anyone is installing and uninstalling on so frequent a basis, what on earth are they doing, leaving unneeded entries and files/folders on their computers until after uninstalling??

Use Revo to uninstall something, and you won't need any 'registry cleaner' to come along some time later and start finding stuff which turns out not to have anything to do with whatever you may have uninstalled earlier. That way, you won't have to wonder about the what-does-this-mean issues you raised. Revo, and the occasional -- very, very, very occasional -- feather-dusting with the always-free CCleaner's own in-built registry cleaner -- and that's it. Job done.

For the average PC user, using registry cleaners is asking for trouble. Without knowing what is okay to remove, you risk breaking programs so that they no longer work correctly. Besides, with modern registries, unless you install and uninstall a lot of programs, you really have no need to worry about it.

@Berlin-Fun*54 (#9):
I think I got the same. Installation ends with a completely black screen (you call it splashscreen). From there everything is frozen, everythin stops.

After closing the cleaner I see an error under the blackscreen:
Security stops the installer from closing the black IE-window.

Ofcourse I will not tamper with my security settings, end of story, no cleaner for me until Athtek fixes this problem.

Suddenly CCleaner is finding a lot more entries. Installed
"Do not Track Me" - maybe it is cleaning up their junk?

You would think there would be some benefits to PROPERLY cleaning a registry after all the installs and uninstalls some of us do, but which areas should be cleaned, and which definitely to avoid changing:

Missing Shared DLLs
Unused File Extentions
Active X and Class Issues
Type Libraries
Application Paths
Help Files
Obsolete Software
Run at Startup
Start Menu Ordering
MUI Cache
Sound Events
Windows Services
Can anyone give me an informed opinion?

With morning coffee at the table I fire up the system to GOTD's site first. I saw AthTek Registry Cleaner and knew it was going to be an interesting comment day :) Correct. As mentioned above, none of the cleaners know what is truly an error based on your unknown configuration. Empty reg keys are my favorite; they are not errors, simply not in current use. Many would point to ongoing projects specific to only one app and not function without the designated key.

Fake awards...... suspicious.
"Registry cleaners" .... snake oil.

If you're running Vista or Win7 you do not need to EVER defrag your registry. EVER. Xp..... maybe once in the lifetime of your machine. Maybe. For 99.999% of people these kind of programs are like land mines. One false step and you're toast. All for illusionary and transient (best possible case) gains. Voted down due to the nature of the program and I almost NEVER do that. Just getting tired of fixing peoples machines after these little gems.

@18. I too settled for Revo uninstaller coupled with CCleaner after varying success with other Registry Cleaners over the years.
Both are controllable and gentle, though Revo is pretty thorough if given its head.
I get very few problems, and those I do get normally show up directly after installing some new software.
Incidentally, Revo has several times shifted Malware progs that others have had to download Log producing software (to be sent to online Experts).
I'm not associated with Revo, CCleaner nor any other software, I just speak as I find.
Both are free.

It auto runs a backup initially and wants to run a backup every time windows starts? (or, is that every time you open the program? Hard to be sure when there are a decent amount of typos and it's evidently a non native English speaking development team. (Which I don't have a bad time about, but I do want to know straight forward what I am agreeing to with automatic operations.)

Registry instead of registration, please rerun &'s! AthTek (after you register) I know nitpicking, but it all adds up to more and more confusion and stronger question of confidence in the program.

Coupled with the award confusion and then considering it a reg cleaner which the reg can render a computer dead and needing a windows reinstall... eh, some of you are more trusting than I am. :)

Trying to be fair I tried 3 registry cleaners
I first went into Regedit... exported and backed up my registry to desktop.

1. CCleaner
Found 7 entries to be removed. (Did not clean)

2. Regseeker (have used for years and never lost a needed file)
Found 160 (Did not clean)

3. AthTek
Found 789
cleaned all 789 entries.

5. Ran all three again after restart.

CCleaner -4
AthTek -233

@sim1 Thankyou sim1 for this reminder.
Forgot about MS RegClean. Before Vista I used Regclean before I did any other PC maintainance, and never got into trouble. So I tried I again. Microsoft discourages use of Regclean, and it can't be downloaded there. ( Google the latest -1997!!- version 4.1a Build 7364.1 ).
So I tested this oldtimer, and yes it finds a lot (hopefully junk...;-)
For routine maintaince I use CCleaner, weed out the lot myself with regedit and recently I have used GAOTD-offerings Wise Care and Advanced Registry Doctor Pro, wisely - as wisely as I can = never do anything automatic.
This is the downside of Regclean: it won't let you review what it finds. SO - be careful, use system restore pionts etc etc while experimenting with good ol' Regclean.
But I must say one again: it really does seem too work...

After using it found about 1000 registry errors...but once rebooting my system I performed another scan and guess what? It found again 1000 errors....LOL...it looks like even the registry errors are FAKE!

So it would be nice if the developer wrote a couple of lines to explain us such a weird and suspicious behaviour of his app!!

For anyone tempted to DL this and install, do note the developer's own words:

It wins in extreme scanning breadth and depth, so that it can find more registry entries than any other registry cleaner.

What that means, is: its scanning engine has been programmed by the developer to go into your computer with a high-pressure hose rather than a feather duster.

You're not signing up to a little light dusting, the kind of thing which would, for instance, easily tidy up that pesky MRU list. You're signing up to a full-scale assault on registry entries which the programmer -- someone you don't know, someone who has never heard of you and certainly hasn't the foggiest notion how your particular machine is configured -- which this unknown programmer *thinks* needs cleaning up.

Never mind whether you can 'restore' the registry afterwards. (Though actually, you should mind: restores aren't guaranteed to work.) Never mind that you can create a Restore Point in Windows and roll back to it. (Though you should mind: System Restore is anything but the certainty so many claim it to be.)

I ran this cleaner last year when it first appeared on GAOTD. Its scan results were hugely impressive. Because they were impressively huge. I couldn't see half the errors it had identified because the GUI couldn't display 'em. But the number of 'found errors' was sufficient for me not to go any further and uninstall there and then.

If I am going to go anywhere near my computer's registry, then as with all delicate and precious objects, I'll do so with a feather duster. Or rather, two feather dusters. One is called Revo Uninstaller, which is so well known it really should need no explaining here and which, because it's free, ought to be on everyone's computer:


The other duster is Piriform's CCleaner,


because its registry cleaning function has proved over time to be as light and as carefully considered as it gets.

Today's developer seemingly operates in a quite different world, where the amassing of huge numbers of errors-that-may-not-be-errors, as well as the flaunting of awards-that-may-not-be-awards, go hand in hand.

On which basis, I can't for the life of me fathom why anyone would want to go anywhere near AthTek Registry Cleaner 2.0. Thanks, GAOTD, but definitely, no thanks.

warning!!! if you use SSD installed OS it is not recommended to use registry cleaners and even more dangerous to use defrag feature on such devices.

No proper About information on this company's website and Contact is only by webform. Sorry Athtek, companies that do not say who they are or provide proper contact information aren't getting on my system.

According to their webpage it requires 2 GB hard drive space for installation. A little bloated,maybe???

So, yes, there are potential dangers to using a Registry cleaner, yes it may do more harm than good. BUT the program backs-up the registry automatically before starting unless turned off manually, so any problems can be easily repaired by restoring the old Registry.
@Roger: You are very ill-informed about the registry. As someone who manually edits the registry quite often, there are a number of things that you should know about the Registry:
1) The registry has a set amount of space allocated to it at the front (Fastest) part of the drive. The default settings give it a bit of space to grow, but if you never clean it you will end up having part of your registry on the end (Slow) part of the drive, that will slow down your system significantly. True, it is better to change the registry allocation in the first place, but still, cleaning it reduces size, speeding up the system, mostly not BOOT time, but file access time, etc.
2) Have you ever installed a large Font pack on your computer? Most people know someone who has, it can bring a brand-new, top-of-the-line computer to a crawl. Why? because every Font must load into RAM at boot, & must stay there. The same with the registry. The larger the registry, the less usable RAM you have. Plus the excess fonts take up space in the Registry.
3) Excess registry entries are referenced ALL THE TIME by the system. If you have a System directory entry, it takes 1/100th of a second every time you open, save or run anything. Now imagine you have 100 System directory entries. that is an extra second it takes to do anything. Then you have the entries that point to things that do not exist. Every one of them will search a stack for each system directory if it does not find it where it says it is, then it will refresh the directory tree to make sure it has an up-to-date one. That significantly slows the system EVERY TIME that part of the registry is accessed.
4) No, Cleaning the registry is NOT going to cause a significant speed-up for most users, You will likely never notice the difference, but your hardware will work a little less & will therefore last longer. You can also avoid those pesky Compatibility errors that sometimes pop up when you KNOW it is compatible. Those are usually Registry-based problems.
If you are looking at "Boot time" as the definition of "Running faster" then yes, you are correct, but a well maintained registry does a lot to improve performance.
Now, that being said, I have run this program on a computer that has a significant amount of registry junk. Found 86,000 faults. I went through a good many of them & checked them, The only true concerns I had were with the Uninstaller Entries. I checked, & every one of the 'Errors' it reported are NOT Errors & should not be deleted. I then continued to run the program again as a different Administrator account, It returned 15,000 errors, Meaning it looks at the User-level registry as well, Again, Uninstall entries were the only real concern, with a few minor concerns with some of the 'Settings' category entries that I was uncertain about & was too much monotony to investigate further. I do NOT like how it cannot be run for a Non-Administrator account on the User Registry only, as that is where most of the Registry problems tend to occur & I hate making them Admins, even temporarily. With all that said & done, I would still recommend Comodo (Which is free) over this.

Even reputable registry cleaners can be dangerous and cause problems. How much worse to use an unknown one from a company which posts fake awards. I think GOTD should be more selective and vet the software a little more and not allow companies with fake awards.

Forget about big thumbs down ratio. Forget about all negative comments. Download and install this Gem and use it. Then all of you beleived through your hearts that why I praise this good written software. I have used so many registry cleaners-Actually I am addict of using the registry cleaners-Sorry for my poor grammer.

I am a little skeptic (paranoid, perhaps?) about using third party software which attacks internals. Prima facie, I have not found any need to use Registry Cleaner, since the improvement that you may feel is generally illusional!

I will let this pass. Thank you.

The fact that they are promoting it in this way:
"It wins in extreme scanning breadth and depth, so that it can find more registry entries than any other registry cleaner." is a real danger signal.
Amount of entries found is NOT a valid measurement of registry cleaner effectiveness in my experience, and in fact, can be an indicator of potential registry problems being caused by the cleaner.

Have fun!

Do you really want to "clean" your REGISTRY with some software that "clean"?

The app in unable to make changes to a non-Administrator account. Do the developers not realize there are user-level registry entries that are kinda important to be able to edit for the idiot-level users?

There is no need to ever clean the registry no matter how much you use your computer. Over time lots of errors will accumulate in the registry - but there is absolutely no need to ever clean them.

More than 99% of so call registry errors are completely harmless and it pointless removing them.

It is exceptionally rare indeed for cleaning the registry to make your computer run faster or to fix any problems.

There is a good chance you could cause harm to your system by using today's giveaway.

I am done using registry cleaners. The only time I used a cleaner was a disaster. Only one time I needed to use a registry cleaner to install a program that xp refused to install and all I did of the 200 suggestion I deleted only one registry line and left the others and the pc is working fine. The last thing I need an aggressive cleaner. Also is registry cleaner something that you need a "regular automatic operation"

Microsoft RegClean is still my best choice.

AthTek might want to change the wording of their product description. Some people might find their use of the phrase 'final solution' rather offensive.
