Basic Knowledge of Windows
Registry and Registry Cleaner
What is the Windows
The Windows Registry is the place on your PC where Windows
stores information it might need to retrieve later. For example,
when you open an application or change a system setting, the
information is stored in the Windows registry. The registry contains
profiles for each user, the applications installed on the computer
and the types of documents they create, what hardware exists on the
system, and the resources being used. The Windows registry consists
of registry hives.
Why should I clean my registry?
Over time, the Windows Registry can begin to contain information
that's no longer valid or no longer useful. Maybe you uninstalled an
application without using the Add or Remove Programs function in the
Control Panel, or perhaps an object or file in the registry got
moved. Eventually this orphaned or misplaced information accumulates
and begins to clog your registry, potentially slowing down your
system and causing error messages and system crashes. You might also
notice that your PC's startup process is slower than it used to be.
Cleaning your registry with a reliable registry cleaner is the
easiest way to help avoid these common problems.
Can't I just delete registry items on my own?
We don't recommend trying to remove registry items on your own.
It's often difficult to determine which items correspond to which
applications, and by attempting to remove items yourself, you might
accidentally remove a valid registry item, causing software crashes
and errors. CleanMyPC Registry Cleaner is a safe and effective tool
to clean your Windows Registry.
What if the registry cleaner removes something I need in my
Don't worry. Our registry cleaner has two layers of backup
function which will help in this situation. Layer 1, it has a full
registry backup/restore function. You can create a full system
registry backup with our registry cleaner. If you need restore the
registry some times later, you can just use the full registry
restore function to restore it. Layer 2, our registry cleaner will
create a registry backup each time it makes changes to your registry
after the scanning/fixing. If you found any problem in your system
after cleaning, you can just undo the changes (with the undo changes
function in our product) to roll back the changes.
How often should I
clean my registry with CleanMyPC Registry Cleaner?
We recommend a complete registry scan/clean with our registry
cleaner once per week.
