What is Windows Registry?
The Windows registry is a central hierarchical
database in Windows used to store information necessary
to configure the system for one or more users, applications,
and hardware devices. The registry contains information
that is constantly referred during operation, such as
profiles for each user, the applications installed on
the computer and the types of documents each can create
property sheet settings for folders and application
icons, what hardware exists on the system; and which
ports are being used. Windows registry is a vital part
of Windows, if it is damaged; your whole system may
be corrupted and cannot be used.
Why
would you need to use Registry Cleaner?
| There
are several reasons why you might need to repair
your registry. Here are just a few: |
- Viruses: Many viruses attack
through the registry by creating or modifying
keys. Unless you have a thorough knowledge of
your system and registry keys or specific direction
from a technical expert on how to search for
these infected keys, it is very dangerous to
try to edit the registry on your own. Any damage
done to the registry at this point would require
either a reinstallation of the registry from
backup or a reinstallation of Windows. Either
way, there will be some information lost.
- Tracking programs: Programs
that install themselves through Internet pages
and track your Internet usage to transmit data
back to their hosts usually have registry keys
associated with them. Some have multiple keys,
under multiple program names or in multiple
folders, within the registry. In order to fully
eradicate the program from your computer, you
must delete all of its associated registry keys.
This can be very tricky.
- Uninstalled programs: If
you have recently uninstalled programs without
going through the official uninstall program
(or if the program did not have an uninstall
feature and you deleted it) there may be some
keys remaining in the registry. Without removing
these keys you may encounter errors, as Windows
will try to operate based upon the keys. In
order to fully uninstall the program, you will
need to remove the associated keys.

| These
are only a few of the reasons you may need to repair
your registry. If you encounter registry errors
for reasons other than this, try repairing the registry. |
