Tweaking.com - Registry Compressor v1.1.0

Registry Compressor rebuilds the registry to new files to make the registry smaller and faster.

The Windows Registry is a hierarchical database that stores
configuration settings and options on Microsoft Windows operating
systems.

Just like databases the registry can become bloated and large when
there has been a lot of additions and deletions from the registry. When
this happens the system can become slower and use more CPU as
programs and the operating system take longer to read and write to the
registry, just like any other database.

This program does NOT remove or add anything to the registry. What it
does is it rebuilds the registry to new files, when this happens all the
overhead is gone and the registry is smaller and faster.
