Registry Cleaners might get you in trouble

Be very careful if you want to use a registry cleaner if you have products like AutoCAD, AutoCAD Architecture or the like installed. These programs are quite sensitive to the problems that some registry cleaners create for them. It can lead to that some functions no longer works or even that you cannot start the application. Sometimes you can repair the installation and sometimes you even have to reinstall the application to get it working again.

Some examples of registry cleaners that have resulted in these problems are:

  • Abexo Free Registry Cleaner
  • Eusing Free Registry Cleaner
  • Norton SystemWorks
  • Registry Mechanic
  • Microsoft RegClean utility

Some Autodesk Knowledge Base document that deals with these problems:

Another mentioning is in this blogpost No Properties in your AutoCAD Properties Manager? Perhaps it was an Overzealous Registry Cleaner.

Some advices if you still want to use a registry cleaner.

  • If possible backup the registry so you can restore or undo the changes it if any problem shows.
  • To avoid this problem, it is recommended that you configure your registry cleaner so that it does not scan Active X Com Sections and Active X Com Sub Key Sections

    I dont agree with you when you overlook the importance of registry cleaner. There is no question that a problem can be caused by invalid references in registry, which can cause multiple problems such as pc crash,slow performance etc. Now one needs to find & remove those invalid references. Finding them manually & repairing can be a duanting task. Here, comes the role of a windows registry cleaner. So my vote will go with those software. Sorry Author about not agreeing with you.

    There are plenty of windows registry cleaner in market. but the best one for me is RegBooster(

    The plus points of the software are:
    - easy to use.
    - quick scanning to find errors & repairing them.
    - ignore list(does not find/count that entry as an error on next search)
    - registry defragmentation
    - registry backup
    - manage startup
    - excellent look & feel.

    You can download it from:

    I agree that registry cleaners can be useful and I myself have used them several times.

    I just wanted to warn about some trouble you might run into if you are not cautious. Many novice users run the registry cleaner and then cannot get for example AutoCAD to run correctly and may spend days trying to reinstall, etc.

    Thanks for the tip about RegBooster.

    I agreed with you, registry cleaner user must backup their system before repairing, some registry cleaner provides ignore list, if you encounter any problem just restore the repair and manually add the key list. However, commercial registry cleaner should have solve this kind of problem or why do we still pay them for?
