paw51, I must advise you to no longer use Ccleaner's registry cleaner. Cleaning out your junk files is a good idea, but registry cleaning can be useless at best and disastrous at worst (examples include failure to boot and blue screens).

Please read bleeping computer's policy on registry cleaners:

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.

ComboFix is a tool used in malware situations and,  Please read the comments by quietman7 at http://www.bleepingcomputer.com/forums/t/362516/combofix-wont-run-on-xp/?p=2029852 .


ComboFix is not something used for any other purpose, it is not used troubleshoot system problems...it's only use in for infected systems..


If you have malware on your system, let me know and I will move this topic to the proper forum for that situation.  The Win 7 forum does not handle malware siuations at all.


If you are talking about other types of system tools...yiou need to specify that.
