Hello,

I was going through a cleaning process of my computer and was following some directions on wikihow. One of the directions given was to download PC Tools Registry Mechanic. It scanned my registry and found 162 errors in my system. The original scan netted over 200, but the tool repaired some of them. The problems range from low to High Priority, and seem to be in the registry..all having something to do with the HKEY files being 'missing or invalid'. It also says that my system health is 'low'. That's all I know. I scanned with Trend Micro, my antivirus software, regularly...as well as with MalwareBytes, and just now, I downloaded Ad-Aware and its scans netted nothing. What is wrong with my computer and how can I fix it? Do I have deep hidden issues? I need help...thanks!

Hello,

What issues were you experiencing that led you to clean your computer? What sort of cleaning? Maintenance type or infection type? As for the "problems" Registry Mechanic found, they likely aren't problems at all. In fact "fixing" these problems could very well cause some programs to malfunction or even the computer itself. I recall borking one of my programs by using a registry cleaner. Fortunately, I had backed up all the keys and was able to restore them.

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.Orange Blossom :thumbsup:
