TuneUp Registry Defrag
Every new program and every new hardware component enters itself in the registry,
creating keys and values. Over time, the central Windows database gets larger and larger.
The larger the registry becomes, the longer the system needs to find specific information,
and this makes Windows slower.
When you remove the software or the hardware component, these keys and values are
usually deleted, but the registry doesn't get any smaller. Why? The space that was
occupied by a deleted key is still in the registry, even if it is no longer used. Sooner or later,
your registry looks like Swiss cheese with lots of holes. It can be 13 MB large, but only
contain 9 MB of information. This slows your system down and wastes space, both on your
hard drive and in the memory.

Analyzing the registry
, however, can also compress the registry, making it
considerably smaller. This also contributes to increasing the performance of Windows. The
module analyzes the old registry and from it creates an entirely new version that contains
only the valid data in the correct order. Once this step is complete, the old registry is
deleted and automatically replaced with the new one when the system restarts.
TuneUp Registry Defrag begins by showing you how heavily fragmented your registry is.
