Type
Description
use by more than one application. If the specified files are moved
or deleted, the references may become invalid.
Help files The registry contains information about which
folder contains the
help files for a given application. If the specified help files have
been moved or deleted, this part of the registry may contain
incorrect entries.
Fonts The fonts that are installed in Windows are registered in a special
part of the
registry. Errors in this part of the registry should be
corrected in any case, because Windows will unsuccessfully
attempt to load the corresponding fonts every time the system is
started.
Installed programs In the Control Panel, the "Programs and
Features" entry in Vista
("Add and Remove Programs" in older versions of Windows) lists
the programs that you can remove from your system. This list is
generated from a special part of the registry, which can also
sometimes contain errors.
System extensions
The registry contains references to system extensions such as
audio and video codecs or Internet Explorer add-
ons that enhance
the functionality of media player programs and Internet Explorer.
References to these system extensions can become inv
alid if the
extensions are moved or deleted.
Windows Firewall The Windows Firewall stores information about which applications
can accept incoming network connections. When such
applications are moved or deleted, the corresponding information
can also be removed.
Program settings Every program installed on your system can store
program-specific information, such as data or program
paths, in the registry. These entries may not always be
correct and are sometimes left behind by a failed or
manual uninstall process.
Database driver Database drivers and data sources can be installed or
registered in the registry. They are sometimes needed by
programs even if your computer isn't used primarily as a
database server. These entries may not always be correct
and are sometimes left behind by a failed or manual
uninstall process.
As you can see, deleted files can leave behind many "ghosts" in the registry. TuneUp
RegistryCleaner finds the orphaned entries and can selectively delete them.
Explanations can be provided for every single problem, if desired. For this, simply click one
of the listed problem categories under the Categories bar.
