Cleaning the Registry
In the following chapters, you will find out why it is important to do so and how you can use the TuneUp
Registry Cleaner tool to clean the registry:
All modifications to your system will be monitored by TuneUp Rescue Center and can be undone if
necessary.
Cleaning the Registry - Introduction
The registry is the heart of a Windows system. It is where Windows continuously stores entries (values and keys).
If, for example, you start a program, Windows doesn't call this up directly, but opens it using a key in the registry
that was created when the program was installed. These entries must be deleted from the registry when this
program is uninstalled, because it is no longer needed. Unfortunately, Windows doesn't always delete these
entries properly, which is why a great many invalid entries build up over time.
These entries aren't just created when programs are installed, but also through lots of other everyday tasks. For
example, the history list of recently used documents in the Start menu works using the entries in the registry.
These references become invalid when you move or delete a document. Since Windows doesn't regularly clean
up the registry, we recommend you do it regularly using TuneUp Registry Cleaner.
By cleaning Your registry regularly your whole system and all your programs will be more stable. This is why this
is one of the functions that TuneUp Utilities can also run regularly as part of the Automatic Maintenance.
Before cleanup can take place, the registry must be checked for problems. You can then either fix them all at
once or one by one.
