Have you contacted their customer support? I'm not saying that be be a wise ass, I'm just wondering how well they support the product they sell. Registry cleaners are dangerous to use, as you found out, because it is easy to get rid of stuff that THEY tell you is "bad" when in fact it is registry entries that your OS needs to run correctly.

Have you tried to start your computer in safe mode? If you haven't then try. While you are in safe mode try to restore your computer to a configuration BEFORE you installed PC cleaner. If that doesn't work, let us know and we'll try something else.

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.


It's possible your "purchase" has modified your registry beyond repair with the only option being a format and clean install of your operating system.

As I've said many times, registry cleaners, tune-up programs, and so-called "optimizers" are the current snake-oil of the internet. There are countless free programs like this and apparently some paid ones, as well.

Do not be deceived. They promise performance you can only dream about....but only deliver a bill ($39.95 in this case!) and a computer that is worse off than it was to begin with.

What is sad is that "trusted" PC review sites get paid to "review" these products and give them glowing reviews. of course the more the product advertises on the reviewing site or the bigger the cut that the "reviewing" site gets from sales linked from them, the "better" the review.

It's not unlike McAfee and Norton paying computer manufacturers to install their "trial" software............

Or, what I see more commonly is this: one of these "products" have a "Certified by so-and-so" logo on their website trying to convince you it is legit (usually ones like Microsoft, Forbes, Wall Street Journal, Newsweek, CNET, Softpedia, etc..), but never actually have a link to the "review". And of course, searching for the reviews on the websites of those trusted companies comes up empty (I wonder why... :huh: ).
