Windows could switch processes inside GetMessage, which is the function you call on Windows to wait for something interesting to happen. | |

This includes reading or writing files, receiving characters from a terminal... processes do "system calls" and, as many operations take some time, such as waiting until a character is received, or that a block is read form a disk, this gives the opportunity for the OS to schedule another task. | |
