After SUSE is installed and throughout its use, you will need to modify, customize, and tweak your installation just like you needed to with Windows, or whatever other operating system you are familiar with. Modifications and trying new things is the best way to familiarize yourself with your new operating system.
In SUSE, there are three major places where you can customize your system. There are countless other ways, but the three easiest and most common are YaST, the KDE Control Center (assuming you are using KDE), and the "Configure Desktop" tool.
Many tasks can be accomplished in several of these places, in fact, most of YaST is avaialble through the KDE Control Center. I still recommend opening YaST itself to perform a YaST task because you'll only need to enter your root password once and the interface seems a little simpler.
Linux also uses text files called config files to control various aspects of the software. Accessing these files directly is one of the things that makes Linux great, however it can also make things more complicated for new users; so I suggest sticking with the GUI tools until they are more comfortable using Linux.
In this following section, I am going to list some of the most common tasks new SUSE Linux users will want to perform to configure their computer the way they want it, then try to point out where these tasks can be accomplished. In nearly each case there are multiple places where each task can be accomplished, not to mention modifying the files themselves; but I'm not going to get into that now.
Later in this section, I'm going do describe a few other "adventures" that I have found myself in and share them as suggestions and experiences. While some of these things may not be your "cup of tea", some may get you on the right track for something you are trying to accomplish. As always, remember to back up your data frequently to ensure that minor headaches don't become tragedies.
