I'm using AVG 2013 Free and I also scan with Malwarebytes free once a week. I let AVG pc analyzer run this morning and it shows I have 749 registry errors and also 21,789 junk files that it rated both as very severe problems. I read in the past not to clean my registry but I would like to remove those junk files and also clean my registry. Is there a safe and good program or manual method to do this. I'm still using Windows XP (service pak 3). Hoping to build a windows 7 system soon when finances allow. Merry Christmas everyone.

Bleeping Computer DOES NOT recommend the use of registry cleaners/optimizers for several reasons:
  • Registry cleaners are extremely powerful applications that can damage the registry by using aggressive cleaning routines and cause your computer to become unbootable.

    The Windows registry is a central repository (database) for storing configuration data, user settings and machine-dependent settings, and options for the operating system. It contains information and settings for all hardware, software, users, and preferences. Whenever a user makes changes to settings, file associations, system policies, or installed software, the changes are reflected and stored in this repository. The registry is a crucial component because it is where Windows "remembers" all this information, how it works together, how Windows boots the system and what files it uses when it does. The registry is also a vulnerable subsystem, in that relatively small changes done incorrectly can render the system inoperable. For a more detailed explanation, read Understanding The Registry.
  • Not all registry cleaners are created equal. There are a number of them available but they do not all work entirely the same way. Each vendor uses different criteria as to what constitutes a "bad entry". One cleaner may find entries on your system that will not cause problems when removed, another may not find the same entries, and still another may want to remove entries required for a program to work.
  • Not all registry cleaners create a backup of the registry before making changes. If the changes prevent the system from booting up, then there is no backup available to restore it in order to regain functionality. A backup of the registry is essential BEFORE making any changes to the registry.
  • Improperly removing registry entries can hamper malware disinfection and make the removal process more difficult if your computer becomes infected. For example, removing malware related registry entries before the infection is properly identified can contribute to system instability and even make the malware undetectable to removal tools.
  • The usefulness of cleaning the registry is highly overrated and can be dangerous. In most cases, using a cleaner to remove obsolete, invalid, and erroneous entries does not affect system performance but it can result in "unpredictable results".

Unless you have a particular problem that requires a registry edit to correct it, I would suggest you leave the registry alone. Using registry cleaning tools unnecessarily or incorrectly could lead to disastrous effects on your operating system such as preventing it from ever starting again. For routine use, the benefits to your computer are negligible while the potential risks are great.Louis

The last time I used any Registry Cleaner / Checker, I had well over 500 "Bad Files" installed, but most were just unused programs and add-ons

I have 749 registry errors and also 21,789 junk files that it rated both as very severe problems.

At least 90% of these are "Minor" cleanup items that can be solved with Windows built in tools.
Go - Start > Programs > Accessories > System Tools > and run Disk Clean-up then Disk Defragmenter.

Next -
Please download AdwCleaner by Xplode onto your desktop.
If you are prompted, please disable your Antivirus - Information (temp disable) HERE
Close all open programs and internet browsers.
Double click on AdwCleaner.exe to run the tool.
Click on Search.
Please post the content of that logfile with your next answer.
You can find the logfile at C:\AdwCleaner[S1].txt as well.

Finally -
To clean out more of your temporary internet files and temp files.
Download TFC by OldTimer from http://www.bleepingcomputer.com/download/tfc/ to your desktop.

Double-click TFC.exe to run it.
Note: If you are running on Vista / Windows7, right-click on the file and choose Run As Administrator
TFC will close all programs when run, so make sure you have saved all your work before you begin.* Click the Start button to begin the cleaning process.
* Depending on how often you clean temp files, execution time should be anywhere from a few seconds to a minute or two.
* Please let TFC run uninterrupted until it is finished.Once TFC is finished it should restart your computer. If it does not, please manually restart the computer yourself to ensure a complete cleaning.

Thank You -

OK, TFC ran for almost 40 minutes and removed a ton of stuff. Very Cool!! I do use the Tools menu in IE and internet options to delete temp files like once a week but obviously that is not doing much. Thanks very much for the TFC referral.

Hi, Just as a follow up I did some informal testing where I took fresh installs of XP.
Then I ran registry repair and cleaner type programs. On a fresh install of XP where nothing had been installed and then uninstalled and it had not been connected to the internet, Those programs found errors.

Seeing that they found errors in a new install of XP I decided they were useless.
The ratio for chance of damage to benefit made me decide not to use them.

Hope that helps
