Before installing an Operating System for a System Unit, one must adhere to the fact that not all machines are the same and that will include software and hardware compatibilities. Aside from that, we as computer hardware servicing technicians should be able to establish a strong background in the proper procedure of installing and operating system. In some occasion, a computer technician is satisfied with the plain installation as long as it works fine. As a responsible computer hardware servicing technician, one must consider to use utilities, ensure data security is met and the computer should be properly optimized to make an ease of use for the client. We will be listing down the things a computer technician should do or check upon when installing an operating system.
