98Lite settings
When installing or Optimising with 98Lite, the following are the only options you must leave/install to run your PC for Audio only:
1. DOS command files - some applications/drivers may need this
2. Multimedia>DirectX Media & ActiveMovie - This is a definate requirement for DirectX components e.g. plug-ins etc
3. Multimedia>DirectX - A fundamental requirement of lots of applications/plug-ins
4. System tools>Application Compatability (Windows ME Only) - May help with software compatability
5. System tools>Disk Defragmenter - You may not want to install this if you are going to use a 3rd party defragmenter such as Diskeeper or Speeddisk
6. System tools>Scandisk - It is highly reccomended that you install this since Windows access to it will have to entirely disabled if you don't
Apart from those, you can remove/disable installation of everything else - this will lead to a very lean Windows installation which will be nice and stable (comparatively at least).
Remember to defrag after installation before you do anything else...
