1. To prevent data loss, backup your data files frequently.
I know how important my log is to me. If my computer should decide to go crazy when it is writing data, I don’t want to lose my work. Therefore I always make a copy of the year I was last working on, so I only can lose what I have just entered.
2. Remove unneeded Inits, Control Panels and Extensions.
Do this to lessen the chance of conflicts with the system.
