Insight from Denmark, Part 1: Portable registry cleaners

Hello there and welcome here. My name is Peter and I live in Denmark. This is, of course, my first post on dotTech.

I learned of Ashraf via Giveaway of the Day and have followed his blog,, for a long time. I work with computers doing maintenance and/or troubleshooting on a daily basis and figured I could pass on some personal knowledge to my fellow dotTechies.

Today, I will discuss 3 portable programs I use to clean computers:

  • CCleaner
  • Glary Utilities
  • Wise Registry Cleaner

It was difficult at first when I first started to use registry cleaners. I did not know anything about the registry but I did know if you make any false moves in there (i.e. delete the wrong things), you may have to reinstall the software (or even your whole OS) that was damaged in the registry. However, everyday my computer was getting slower and slower so I was forced to think in new ways and learn about the registry, because I need my computer – without it I am lost.

So, after trying several different things to try to speed up my computer, I decided to learn about the registry and how to clean it.

First I started with CCleaner…

…because many sites I surfed mentioned CCleaner as a safe and reliable cleaner. At the beginning I would delete only the TEMP files (temporary files). However, after a while, when I had the time to look at every entry in the registry CCleaner was asking me to delete, I gained the courage to clean more than just TEMP files. From my experience, I learned a lot  about the significant entries; I could trace them all, or nearly all, to what they do and what program program they belong to.

In my time experimenting with many different registry cleaners, I discovered many registry cleaners come with an explanation on why you can delete the entry, and they categorize them in temporary files, missing references, unused extensions etc.:

After I played around with many registry cleaners, commercial ones and free ones, I could see that the trials of the commercial registry cleaners you only can delete 10-20 entries at a time even though they find about 2-900 deletable entries. The problem was, I was helping other with their computers around the same time I was experimenting with registry cleaners, so my need dictated something less restrictive. There I went searching for something safe and reliable, yet simple and free to use everywhere. In the end, I found the 3 free (portable) registry cleaners that fit my needs and can work well for you too.


As I already mentioned, CCleaner was the first program I used for registry cleaning, and I have stuck with it, because it is free, and safe.

CCleaner is so reliable, with CCleaner I usually just delete the suggestions it makes without giving it a thought.

However, I would like to say something for the TEMP files cleaning: it can help a program to run again by fixing, for example, error messages. However, at the same time, think twice about delete TEMP files because deleting TEMP files for a program that needs the TEMP files may cause issues because sometimes TEMP files store user data and such (think browser cookies and cache as an example).

Glary Utilities

At first I thought Glary Utilities is the same as Ccleaner, but after studying the suggestions of Glary Utilities, in terms of cleaning the registry, I could see that Glary Utilities finds different errors than CCleaner but is also safe to use. Because Glary Utilties is portable it was easy to test it on other machines without leaving any trace on the computer that the program has been there, and that is a thing I like very much. Remember, you do not want to spend time to install and then uninstall a registry cleaner.

Wise Registry Cleaner

Initially I used the installer version, not portable verison, of Wise Registry Cleaner, because at the time I did not know there is a portable version of Wise Registry Cleaner. However I am glad I used Wise Registry Cleaner, even though I had to install it, because it found around 400 entries to delete (safely) the first time I ran it, and it had a good explanation for what each entry is, what it is for, and what category it belongs to. If you do not know many things about registry try to scan your computer with this software, highlight individual entries, and see on the bottom of the window what it is for a file and why you can delete it; this way you can learn a lot about registry and registry cleaners. Of course if you scanned your computer for learning purposes only, you can always choose to not delete anything, closing the program after you read all the info. With Wise Registry Cleaner, only the registry entries which are “safe” to delete are checked for deleting by default; however you can always manually check the other entries there are a lot of possibilities here if you want to go further.

I use all three programs I just mentioned to clean my computer and others. One of the biggest reasons I find them all so useful is all three have portable versions so you can have them on a USB stick and clean computer after computer without having to install anything. The other main reason I have used these three is because I have had any problems after cleaning computers with them if I use the safe/default mode of course.

You can use them separately or together. Together they clean better, because in one way or another they each find different errors on the computer as they search in different ways.

Personally, I categorize them in  the following 3 steps:

  1. Surface cleaning – CCleaner (TEMPORARY files (choose the files you want to delete) and registry files)
  2. Middle phase cleaning – Glary Utilities  (at default settings)
  3. Deep cleaning – Wise Registry Cleaner (delete the safe ones (they are marked safe) registry files)

Steps 2 and 3 I only do once a month maximum, but CCleaner I use several times during the week.

Note: I did hear that some people have problems using Ccleaner to clean Office 2003 temporary files. However, other people tell me that CCleaner helped them fix a damaged Office 2003 by deleting those temporary files, so unless you have a damaged Office 2003, you can choose to not delete those temporary files with Ccleaner.

That’s it, I am very happy with these programs and find them useful and hope you can find them useful too. I have made many computers run much better, If not as new.

See you in the next article :O).

  • I have never used registry cleaner because I heart the software will delete some important files. i hope there would be other ways to clean and speed up  my computer.

  • @Ashraf:

    Thanks, was forgetting how it is a jungle out there with the apps :Oo

  • @Ashraf: Thanks Ashraf.

    I thought that’s what happened.

    @Steve: I deleted his comment which is why you can’t see it =P.

    @Peter and @Shi: : I would be careful with Wise Disk Cleaner. My experience says it is not good. Check it out at

  • @Shi:
    Thanks for the feedback, now I am getting curios about wise disk cleaner, I know you can get it as portable version too :O). Have a nice sunday

    Thanks, now I start to understand what he is writing about, I will report about you problems with the site to Ashraf. Have a nice time over there

  • @Peter:

    Hmmm…Peter, that’s strange???

    When I went to click on the stenlysimpson link in my post, (for reference) nothing happened, but it works when I clicked on the link to my comment in your post.

    Stenly’s post #15330 seems? to be missing.

    Maybe you should ask Ashraf about it.

    Anyway, stenly’s provided link had an independent researcher? perform tests on 5 or 6 cleaners, and one always seem to mysteriously rise to the top, or nearly so.

    Then at the end of the testing there was a bottom banner asking the viewer to purchase this mysterious front-runner.

    Now I don’t know about Denmark, but let me give you some insight from America.

    If it looks like a duck, walks like a duck, sounds like a duck, and smells like a duck. Then it is a duck.

    Stenly’s link was a spam link, and I fell for it, thinking that with the caliber of users here at dotTech, that something like this wouldn’t happen, but I was woefully mistaken. :(

    Also use cc cleaner, and have not had any probs. with these three apps.

  • @Ron:

    Hi Ron,

    I’ve tried the programs on Windows Vista and
    xp / Proffessional / home center, the computers has been
    ranging from laptops to HP desktop. I’m running
    with XP Professional computer / 1000 MHz CPU / 512
    MB RAM.
    System Restore points do not work on my computer
    if I get too many points ?, that I have discover on
    another occasion. (windows write there is to many
    restore points, please select another day??)

    Here’s how the program works before they delete
    what you have chosen:

    CCleaner: allows you to make a backup of the
    registry files you delete.

    Glary Utilities: creates an automatic backup of deleted
    registry files.

    Wise Registry Cleaner:
    When you first start the program suggests the
    create a system restore point or a full backup
    the registry.
    When you delete something it makes a backup of it.
    Have a good Saturday

  • @Muhammad:
    Hi Muhammad

    Try Advanced System Care
    free and if you like it and want more
    opportunities, buy the Professional version: O)
    Have a nice time over there

  • jumbi

    Although the subject is covered enough from previous articles (except wise cleaner info), let me also congratulate you for your time to create this presentation in a style similar to Ashraf’s “easy reading” !

    This is certainly going to be useful to new readers.

    I do wonder what will be the subject of
    “Insight from Denmark, Part 2” ?!?

    P.S. From , there is also Wise Disk Cleaner. Your comments on that or anyone else who have tested it?

    Also, many readers above have suggested other registry cleaners which are NOT portable, so its out of subject and not comparable…

  • Jyo

    @uno: Wait, are you saying portable registry cleaners are bad?

  • PeterB

    Hi Peter.
    Since you are Peter from Denmark, like me, I will call myself PeterB.
    I have not tested to see if my best 2 free registry cleaners are portable after installation.

    I use these free cleaners.
    1. AML Free Registry Cleaner
    2. Eusing Free Registry Cleaner

    They seem to find more than Advanced System Care (only tested free edition), CCleaner, Registry Help, EasyCleaner, Wise Registry Cleaner.

    So far I have found those 2 safe to use (I use xp pro 32bit). They can create backups of the changes you made also. Check them out.

    For Registry backup, I use windows restore, but also I have found regbak from . Very nice and simpel and it’s free.


  • uno

    Great idea! Portable Registry Cleaners… so you can damage any PCs you see! ;)

  • Hello Peter :D

    Greetings from Canada & Welcome to our neck of the woods aka Ash Country :lol:

    Congrats on your 1st article. Very useful & pertinent!!
    Being bombarded w so much skewed/bad tech information on the Tubes, we are soooooo darn confused its just maddening!!! !!! :twisted:
    We need all the help & insight possible, thats why we rely so much on Ash’s advice!

    So, looking forward to Part: 2, 3, 4, … ;)

    See you around

    BTW I love your blog!

  • Mr. Fred

    Also,…. instead of Glary Utilities,…. use Iobit’s Advanced System Care 3.3.4 … CCleaner is VERY good ! …. & so is A.S.C. 3.3.4

  • Mr. Fred

    I am still a fairly NEW… & .. IGNORANT…. computer user,… but you really need to check out EasyCleaner for registry cleaning (The only caveat is….. do NOT use the “Duplicate Files” tool) all other parts work…. VERY well,…. and in a little over A year,… it has NEVER caused ANY problems in my registry. If you use ERUNT first,… you will have a good copy of your registry to…. VERY EASILY,… Re-install your registry if you should ever have ANY problems.

  • Bob

    Have you documented that cleaning the registry really does make any difference in the speed at which the computer performs operations?

  • Hans

    Hai Peter congratulations for your first Article.

    To speed up my windows XP computer, I am using CCleaners, Advance System Care, Ashammpo WinOptimizer 5, Tune up Utilities 2008 dan Eusing Free Registry, Ashampoo PowerUp XP Platinum 2 (all of them are freebis / promotional items).
    All of the software (i think especially Ashampoo products) give my computer power to run faster.
    I wanna to try Glary Utilities and Wise Registry Cleaner as you mention above.

    Anyway thanks to you for sharing your info.

  • Guest

    Congratulations on your first article, Peter.
    But it would be wise to use the international versions for screenshots, so everyone can read what it says, and not just Danes. Not that it’s a problem for me, because I’m actually a Dane too.

    Oh, well, it’s your first article, so you will get more experienced as you continue to write and read comments.

  • SKYC

    Thank You Peter for your effort.

    I like the portability angle.
    Nicely presented.

    Thumbs Up!


  • Ron

    Greetings Peter!

    Very nice job on the article. I do have a couple of questions.
    1) What operating system/computer did you test with?
    2) Did you set a system restore point so you could go back to the same conditions every time?

    With kind regards,
    Ron Moore

  • Muhammad

    thanks Ashraf

    what about Advanced Systemcare Professoinal?
