There are two types of "resetting". There is the "factory reset" where you restore the computer to the condition it had when it left the factory. That does in fact remove all the work you have done to it since it has been in your possession. That is only for the direst conditions. The second "resetting" is one I have been urging people to do and that has been recommended for computers since they have been around but it requires some preparatory work on the computer owners part. Most computers in recent use have the ability to save their settings into a removable storage device. The CS3 has a USB port where a thumb drive can be inserted. There is a procedure to store the existing settings on it which is recommended by most experienced computer users. It should be done on a regular basis and before any updates. No one should ever recommend that you "reset" your CS3 without telling you the consequences of a "factory reset" or telling you about the proper way to do it. The second method is often referred to as a "restore" as it restores the computer to an earlier condition.
