10. TuneUp RegistryDefrag
The module TuneUp RegistryDefrag is only available for Windows
95/98/Me and can not be loaded under Windows 2000/XP. This is why
the module is only mentioned at the end of this manual in its own
chapter – it's only useful for users of older Windows versions.
Any new program you install and any new hardware you add registers
itself in the Windows 95/98/Me registry. The registry grows and grows
and because of its size Windows requires longer to find single keys
within it. This slows down your computer.
When programs are uninstalled or the registry is cleaned, many keys are
removed; however the registry size doesn't decrease. This is because the
space the key required is still there, it just isn't in use. TuneUp
RegistryDefrag can remove these unused gaps in the registry so that the
registry's size decreases. This is done by creating a new registry file
containing all existing keys in the correct order and then replacing the
old registry with the new one automatically during the next reboot. With
this small trick, the overall performance of Windows can be improved.
