Yesterday,

                I ran CCleaner and the Registry Cleaner picked up a couple of strange file extensions. They are .16385_none_6079f415110c0210_hosts_d78df635 and .C7483456-A289-439d-8115-601632D005A0.

    I've been running SpyBot 2.2 the last couple of days. Additional utilities I run are, Emsisoft Emergency Kit, TDK Killer

and Tweaking. Additionally, HP Support had me remove KB971033 last night due a licensing pop-up issue. I have an HP Pavillion DV8T 1200 Series Laptop with a Windows SP1 Operating System. Any help would be appreciated. Thank you in advance.

Hello! BC forum does not recommend the registry cleaner in CCleaner! BC does not recommend any registry cleaner. I know you can save the deleted items, but best not to mess with registry cleaners IMHO!!

Just for the record and anyone who reads this topic in future.

Bleeping Computer's position on cleaners and optimizers

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

With all due respect, I'd appreciate a comment regarding my basic question pertaining to an

unknown file extension, not the pros or cons of a registry cleaner. Time for breakfast.

On the other hand, other references to .C7483456-A289-439d-8115-601632D005A0 indicate that it's a  Windows Vista validation update file.
 
It could be the same in Windows 7, but I found no references to it for Win 7.
 
donetao, your first link sends me to a page that has no information on .C7483456-A289-439d-8115-601632D005A0
 
The first entry on the page is something about felony arrests in Los Angeles County in 2002. The ones after it also don't mention .C7483456-A289-439d-8115-601632D005A0
 
CCCleaner will list the PROBLEM and DATA. What did those say regarding the entries you are asking about?
