I used to buy a computer with an operating system, and I came with an operating system instruction manual. You can learn to operate the computer with the instruction manual. The MS DOS instruction manual that was given to me more than twenty years ago was taken back and quickly read.
At that time, to buy a computer, you have to ask the computer store to install the machine, and after the computer store installs the machine, it will generally forget to give the information attached to the floppy disk program to the user. If anyone's computer is broken, please go to deal with it, generally there is no driver, you have to ask the computer store where the machine was originally installed.
Maintaining a computer more than twenty years ago was a technical job. For example, if the network card does not work, it is likely that the address or port conflict, you have to specify the address or port yourself. Is it also necessary to set the interrupt, I forgot.
Now buy Windows, there is nothing, only send the registration code, not even the CD. However, the current computer is also easy to use, and it is not mentally retarded to play and fly. Microsoft's contribution to this is enormous.
