Adjusting Your Application Priorities
Since the introduction of the multitasking processor, operating systems have
been able to run multiple programs at once using the new task switching and
segmentation features provided by the CPU. These new technologies made it
possible for operating systems such as Windows to be created. Even though
PCs today are able to multitask, they still really can do only one thing at a time
per CPU core. For the operating system to support running dozens of
applications at once, it has to slice up all the available processing time and give each
application a turn. Although this is starting to change for consumers with the
introduction of multi-core processors, each core can still do only one thing at a
time. Previously this was possible only on expensive multiprocessor
configurations typically found in servers.
Operating systems use a variety of techniques to determine which application
gets the next available time slot to use the CPU. One of the factors that determines
this for Windows 8 is the priority level at which the application is running.
Every application that runs on your computer has a priority level attached to
its runtime information. By default, the operating system starts each application
