1.     What is registry?

Registry is a
system-defined database which is used by an Operating System to store all the
information needed to configure the Windows settings for 1 or more users,
applications and hardware devices.  Information
contained in registry includes users profiles, application installed on the
computer, types of documents that could be created, setting of properties sheet
for each application folder and icon, existing hardware in the system, and all
the ports that are being used.

Why registry cleaner is important?

When using the
computer, users like you may have experienced quite a number of problems
relating the registry issues that may result in severe consequences such as error
message pop-up, noticeably slow performance of a system or even system crash...The
reasons leading to these problems, however, are mainly caused by missing or
invalid registry key(s) from the Windows registry.

Usually, when
any particular application is uninstalled from Windows, it is recommended that
you should use Add or Remove Programs feature
to proceed. However, if you delete any program manually without using this
function, you might mistakenly move away the registry key in the OS or even
leave behind the orphaned registry key. This, of course, will cause the problem
of missing/ invalid registry entries. Other actions involving include deletion
of startup program, installation of software embedded with spy-ware or changes
in hardwareetc

And because of
the above reasons, cleaning Windows registry has become an essential and crucial
action that you need to implement regularly. Do it timely or you will have to
bear a miserable ending of losing all important data due to the system
breakdown.

3. Can I delete the registry by myself?

The answer is No. When you attempt to remove the registry by your own, the risk that you may remove the valid registry is high because without the software, it is not easy to determine which registry belongs to which application. Therefore this may cause the system to crash or the software malfunction.
